### ABSTRACT

The family Spinturnicidae (Oudemans, 1902) comprises hematophagous mites found exclusively on bats. In this article, we present DNA barcodes (mitochondrial Cytochrome c Oxidase I) for 71 specimens morphologically assigned to six spinturnicid species from 34 bat specimens (11 species) obtained from 10 caves and one forest fragment in karst areas from Minas Gerais state, southeast Brazil. A visual guide with diagnostic characters for *Periglischrus acutisternus* Machado-Allison, 1964, *P. caligus* Kolenati, 1857, *P. herrerai* Machado-Allison, 1965, *P. iheringi* Oudemans, 1902, *P. paravargasi* Herrin & Tipton, 1975, *P. torrealbai* Machado-Allison, 1965 is provided. Along DNA barcode data, photo-documentation of vouchering material of each individual sequenced have been deposited at BOLD (Barcoding of Life Data System v4) database. *Periglischrus herrerai*, *P. caligus* and *P. paravargasi* are reported for the first time in Minas Gerais state, extending their distribution ranges.

### Introduction

The cosmopolitan family Spinturnicidae (Oudemans, 1902) includes hematophagous mites found exclusively as ectoparasites on bats. Their life cycle comprises five stages, all occurring on the host: egg, larva, protonymph, deutonymph, and adult. Of these, the egg and larval stages occur inside the pregnant female (Rudnick 1960), nymphs and adults mostly inhabit the plagiopatagium of bats (Almeida *et al.* 2015).

Currently, Spinturnicidae comprises 12 genera and 110 species (Beron 2020). Among genera, five occur across Americas, associated more or less specifically with four bat families: *Cameronieta* Machado-Allison, 1965b with Mormoopidae; *Periglischrus* Kolenati, 1857 with Phyllostomidae; *Spinturnix* Von Heyden, 1826, a cosmopolitan genus, with Vespertilionidae bats, *Paraspinturnix* Rudnick, 1960, a monotypic genus, associated with the anal orifice of bats belonging to the genus *Myotis* (Vespertilionidae); and *Mesoperiglischrus* Dusbábek, 1968 associated with Natalidae (Dusbábek 1968; Herrin and Tipton 1975; Morales-Malacara 2001; Von Heyden 1826.). Except for *Paraspinturnix*, all of these genera are recorded from Brazil

(Kolenati 1857; Oudemans 1902, 1903; Rudnick 1960; Confalonieri 1976; Gettinger and Gribel 1989; Azevedo et al. 2002; Almeida et al. 2007, 2011, 2015, 2016a, 2016b, 2018; Dantas-Torres et al. 2009; Silva et al. 2009, 2017; Silva and Graciolli 2013; Moras et al. 2013; Lourenço et al. 2016; Bezerra and Bocchiglieri 2018; Lourenço et al. 2020; Vidal et al. 2021).

*Periglischrus* includes 26 species recorded from Neotropics (Morales-Malacara and López-Ortega 2023). Some closely related species are similar enough to make accurate identification difficult. Some authors proposed species groups (e.g., *acutisternus* species group proposed by Morales-Malacara 2001) according to morphological similarity and affinity to their Phyllostomidae bat hosts. Host specificity ranges from monoxenous (a single host species), stenoxenous (a single host genus) to oligoxenous (occur in two or more host genera of the same family) (Herrin and Tipton 1975; Morales-Malacara 2001).

Thus far, fourteen species have been recorded in Brazil (Almeida et al. 2016b; Silva et al. 2017; Lourenço et al. 2020): *Periglichrus acutisternus* Machado-Allison, 1964, *P. caligus* Kolenati, 1857, *P. herrerai* Machado-Allison, 1965a, *P. hopkinsi* Machado-Allison, 1965a, *P. iheringi* Oudemans, 1902, *P. micronycteridis* Furman, 1966, *P. ojastii* Machado-Allison, 1964, *P. paracutisternus* Machado-Allison & Antequera, 1971, *P. paravargasi* Herrin & Tipton, 1975, *P. parvus* Machado-Allison, 1964, *P. ramirezi* Machado-Allison & Antequera, 1971, *P. tonatii* Herrin & Tipton, 1975, *P. torrealbai* Machado-Allison, 1965a, and *P. vargasi* Hoffmann, 1944 (Hoffmann 1944).

Because some *Periglischrus* species are similar enough to make morphological identification difficult (Morales-Malacara 2001) or show extensive intraspecific phenotypic variation related to host species (Almeida et al. 2018; Morales-Malacara et al. 2018, 2020; Zamora-Mejías et al. 2022), the inclusion of molecular data and careful specimen documentation is useful to make identification and occurrence ranges more reliable and reproducible.

The convergence of different methodologies, such as biological or breeding studies, morphometrics and statistical analyses, and molecular tools with traditional taxonomy is a desirable scenario (Łaydanowicz and Makol 2010; Dabert et al. 2011), conducted as part of an integrative taxonomic approach (Knowles and Carstens 2007; Schlick-Steiner et al. 2010).

Herewith, we generated and made available DNA barcoding sequences and high-resolution photographs in the BOLD (Barcoding of Life Data System v4) database (Ratnasingham and Hebert 2007) of six species of *Periglischrus* collected on 11 bat species obtained from Minas Gerais state and provided a visual guide to the diagnostic characters useful to their identification.

# Material and methods

## Specimen sampling, preservation and licenses

We examined a total of 81 specimens, consisting of males, females and nymphs from Minas Gerais state, Brazil. Of these, seventy-one individuals of *Periglischrus* had the cytochrome c oxidase subunit I (COI) gene successfully sequenced. Collection Numbers, BOLD IDs, BOLD Bin, instar/sex, host details, locality, coordinates and GenBank accession numbers are provided in Table 1. Localities are summarized in the map at Figure 1.

Mites were removed from their live bat hosts in the field by careful examination of these animals, using fine pincers and alcohol-soaked brushes, and immediately preserved in 96% ethanol, refrigerated in the field, and stored at -20 °C upon arrival. Bats were collected under ICMBio license SISBIO 71120-4, authorized by the Instituto Estadual de Florestas do Estado de Minas Gerais (IEF 009/2020), in accordance with the precepts of the ethics committee for animal use in research “Comissão de Ética no Uso de Animais (CEUA)” of Universidade Federal de Minas Gerais (UFMG), protocol number 50/2020. Access to the genetic heritage from Brazilian mites was registered in SisGen (register number: A054674).

## DNA extraction, mounting, mites ID, photo-vouchers and collection

Genomic DNA was extracted from single specimens using Chelex based solution Instagene® (BIORAD) incubated for 30 min at 54 °C, followed by 8 min at 100 °C. The solution was spun and approximately 170 µL of supernatant was obtained for PCR reactions. Exoskeletons recovered from extraction were mounted on permanent microscope slides using Hoyer's medium (Walter and Krantz 2009) for morphology examination and kept as voucher material.

Identification and photo-documentation of vouchers were performed using a Leica DM 750 optical microscope with an ICC50 W digital camera attached. Besides, mites identification followed the keys proposed by Herrin and Tipton (1975) and Morales-Malacara (2001), supplemented by original description and re-descriptions, such as Furman (1966), Machado-Allison (1964, 1965a,1965b), Machado-Allison and Antequera (1971), Morales-Malacara et al. (2018), Rudnick (1960), Almeida et al. (2018). The nomenclature for idiosomal chaetotaxy follows Evans (1968) and Domrow (1972), leg chaetotaxy follows Evans (1963). All measurements are in micrometers.

The voucher materials are deposited at the Acarological Collection, Centro de Coleções Taxonômicas, Instituto de Ciências Biológicas, Universidade Federal de Minas Gerais, Belo Horizonte City. Collection acronym: UFMG AC. The map was prepared using QGIS 3.22.1 (https://www.qgis.org/ko/site/).

## PCR, sequencing and chromatogram checking

The amplification of mitochondrial cytochrome c oxidase subunit I (COI) fragment of ~1200 bp was conducted using the primers and protocols described by Klimov *et al.* (2018). Amplifications were performed in 20 µL of final volume, with Platinum Taq DNA Polymerase (Invitrogen) in a Mastercycler nexus (Eppendorf) thermocycler. The master mix for initial PCR contained 2.0 µL of PCR buffer (1X), 1.4 µL MgCl2 (50 mM), 1.4 µL of dNTP (10 mM each) and 0.8 µL of each oligonucleotide primer (10uM), to which 7–10 µL of genomic DNA was added or alternatively 0.5 µL of parent PCR products. All PCR products found positive in 1% agarose gel electrophoresis were purified using the Ampure® (Agencourt) kit and sequenced using a 3730 DNA Analyzer and BigDyeTM Terminator v3.1 (Applied Biosystems) according to the manufacturer's protocol, employing M13 forward and reverse primers.

Forward and reverse chromatograms were checked, edited and assembled into contigs using software ChromasPro 1.41 (Technelysium Pty Ltd). All sequences generated for this study were compared with available mites sequences using the BLAST feature (https://blast.ncbi.nlm.nih.gov/Blast.cgi) (Altschul *et al.* 1997) and deposited in GenBank database (Table 1).

## Alignment and phylogenetic inference

After preliminary automatic alignment with the aid of the MUSCLE software (Edgar 2004) sequences had their extremities trimmed and checked for the maintenance of the reading frame in the program MEGA 7.0 (Kumar *et al.* 2016). All sequences were uploaded into BOLD (Project-SPIN: DNA barcode library for Spinturnicidae mites from Brazil) database that assigned Barcode Index Number (BIN) (Ratnasingham and Hebert 2013). Pairwise mean interspecific and intraspecific p-distances values were calculated in MEGA 7.0. Haplotypes were identified employing DnaSP V. 6. and the alignment filtered from redundant sequences. The best-fitting models of nucleotide substitutions were found in ModelFinder (Kalyaanamoorthy *et al.* 2017) using Bayesian information criterion (BIC) as implemented in IQTree (Nguyen *et al.* 2015). This algorithm tests best fit models for each partition and the best partitioning scheme. The partitions taken into account were codon positions (1st, 2nd and 3rd).

Maximum likelihood (ML) tree was obtained in IQTree, with support being estimated using UltraFast Bootstrap (UFBoot) and SH-like approximate likelihood ratio test (SH-aLRT) was calculated in IQTree with 1,000 replicates. The bayesian inference (BI) was run on Beast v. 2.4.6 (Bouckaert *et al.* 2014). The analyses were run for $3 \times 10^8$ generations, sampled every $3 \times 10^4$ generations, under the Yule tree model. Convergence check using Tracer v.1.6.0 (Rambaut *et al.* 2014). The resulting trees are summarized using the software TreeAnnotator v1.8.4 (Drummond *et al.* 2012), with a 10% burnin, on the maximum clade credibility tree displaying the median heights for the tree nodes. Leading to an ultrametric bayesian tree.

Finally, two methods of putative species delimitation were performed: the Bayesian implementation of the Generalized Mixed Yule Coalescent algorithm (bGMYC) model (Reid and Carstens 2012) was used to delimit putative species belonging to different haplotypes following Costa *et al.* (2019) and Gomes-Almeida *et al.* (2023); and *Assemble Species by Automatic Partitioning* (ASAP) analysis (Puillandre *et al.* 2021), based on genetic distance calculated between DNA sequences and ranked by their ASAP-scores, was performed without the outgroup, with default settings and Kimura K80 substitution model (ts/tv=2.0) through the web-server accessible at via the webserver (https://bioinfo.mnhn.fr/abi/public/asap/asapweb.html), using fasta files for locus COI as input file.
## PCR, sequencing and chromatogram checking

The amplification of mitochondrial cytochrome c oxidase subunit I (COI) fragment of ~1200 bp was conducted using the primers and protocols described by Klimov *et al.* (2018). Amplifications were performed in 20 µL of final volume, with Platinum Taq DNA Polymerase (Invitrogen) in a Mastercycler nexus (Eppendorf) thermocycler. The master mix for initial PCR contained 2.0 µL of PCR buffer (1X), 1.4 µL MgCl2 (50 mM), 1.4 µL of dNTP (10 mM each) and 0.8 µL of each oligonucleotide primer (10uM), to which 7–10 µL of genomic DNA was added or alternatively 0.5 µL of parent PCR products. All PCR products found positive in 1% agarose gel electrophoresis were purified using the Ampure® (Agencourt) kit and sequenced using a 3730 DNA Analyzer and BigDyeTM Terminator v3.1 (Applied Biosystems) according to the manufacturer's protocol, employing M13 forward and reverse primers.

Forward and reverse chromatograms were checked, edited and assembled into contigs using software ChromasPro 1.41 (Technelysium Pty Ltd). All sequences generated for this study were compared with available mites sequences using the BLAST feature (https://blast.ncbi.nlm.nih.gov/Blast.cgi) (Altschul *et al.* 1997) and deposited in GenBank database (Table 1).

## Alignment and phylogenetic inference

After preliminary automatic alignment with the aid of the MUSCLE software (Edgar 2004) sequences had their extremities trimmed and checked for the maintenance of the reading frame in the program MEGA 7.0 (Kumar *et al.* 2016). All sequences were uploaded into BOLD (Project-SPIN: DNA barcode library for Spinturnicidae mites from Brazil) database that assigned Barcode Index Number (BIN) (Ratnasingham and Hebert 2013). Pairwise mean interspecific and intraspecific p-distances values were calculated in MEGA 7.0. Haplotypes were identified employing DnaSP V. 6. and the alignment filtered from redundant sequences. The best-fitting models of nucleotide substitutions were found in ModelFinder (Kalyaanamoorthy *et al.* 2017) using Bayesian information criterion (BIC) as implemented in IQTree (Nguyen *et al.* 2015). This algorithm tests best fit models for each partition and the best partitioning scheme. The partitions taken into account were codon positions (1st, 2nd and 3rd).

Maximum likelihood (ML) tree was obtained in IQTree, with support being estimated using UltraFast Bootstrap (UFBoot) and SH-like approximate likelihood ratio test (SH-aLRT) was calculated in IQTree with 1,000 replicates. The bayesian inference (BI) was run on Beast v. 2.4.6 (Bouckaert *et al.* 2014). The analyses were run for $3 \times 10^8$ generations, sampled every $3 \times 10^4$ generations, under the Yule tree model. Convergence check using Tracer v.1.6.0 (Rambaut *et al.* 2014). The resulting trees are summarized using the software TreeAnnotator v1.8.4 (Drummond *et al.* 2012), with a 10% burnin, on the maximum clade credibility tree displaying the median heights for the tree nodes. Leading to an ultrametric bayesian tree.

Finally, two methods of putative species delimitation were performed: the Bayesian implementation of the Generalized Mixed Yule Coalescent algorithm (bGMYC) model (Reid and Carstens 2012) was used to delimit putative species belonging to different haplotypes following Costa *et al.* (2019) and Gomes-Almeida *et al.* (2023); and *Assemble Species by Automatic Partitioning* (ASAP) analysis (Puillandre *et al.* 2021), based on genetic distance calculated between DNA sequences and ranked by their ASAP-scores, was performed without the outgroup, with default settings and Kimura K80 substitution model (ts/tv=2.0) through the web-server accessible at via the webserver (https://bioinfo.mnhn.fr/abi/public/asap/asapweb.html), using fasta files for locus COI as input file.

# Results

## Molecular analyses

We obtained 71 COI sequences of *Periglischrus* mite specimens morphologically assigned to six species, collected from 11 species of bats from Minas Gerais state. Sequences ranged from 657 to 953bp due to poor chromatogram quality due to repeated bases or mixed trace signals (multiple peaks) on their extremities. Among the 71 sequences, trimmed to 654 bp, 61 different haplotypes were identified. Intraspecific mean p-distances among sequences varied from 0.0006 (0.06%) in *P. herrerai* (n= 5) to 0.0322 (3.22%) in *P. torrealbai* (n= 6), among *Periglischrus* species, interspecific p-distances varied from 0.1255 (12.55%, *P. herrerai* x *P. caligus*) and 0.1833 (18.33%, *P. caligus* x *P. acutisternus*). Pairwise mean intraspecific and interspecific p-distances are summarized in Table 2.

ModelFinder chose as best partition/model according to Bayesian information criterion (BIC) the first, second and third codon positions merged in a single partition under the model TIM+F+I+G4. Bayesian Inference and Maximum Likelihood phylogenetic inference resulted in six groups of *Periglischrus* species with clades that are highly supported, corroborating the previous morphological identification of the mites (Table 3; Figure 2; Supplementary figure 1-2). Eight BINs were identified by BOLD, five created from our data and three that matched existing BINs (Supplementary Figure 3). For bGMYC analyses, identified 10 species, with posterior probability being p < 0.95 (Figure 2), while the best partition provided by ASAP identified six hypothetical species that match six morphological species delimitations, observed a barcode gap of about 8-14% at the threshold distance of 10.57% (K80; 2.0) which has the best ASAP-score (1.50) within the available molecular data (Supplementary figure 3).

Below, we provide an annotated list reporting the six species of *Periglischrus* mites found, along with information on their distribution, host, COX1 barcode sequence data, and high-resolution photographs of diagnostic characters. All localities in Minas Gerais state, Brazil. Coordinates are given in WGS-84 format.

Maranhão, Paraná and São Paulo (Confalonieri 1976), Minas Gerais (Confalonieri 1976 and present study), Rio de Janeiro (Lourenço et al. 2016); Mato Grosso do Sul (Silva et al. 2017).

**Differential diagnosis** — *Female:* large, idiosoma length less than 2.000 µm (n=3, 1.167–1.352, 1.279) (Figure 3A); dorsal opisthonotal area with four pairs of minute setae (Figure 3D); sternal plate has a flask-shaped with a narrow, subtriangular, median sclerotized projection at the anterior end of the plate (Figure 3E–F); distal posteroventral (*pv*) setae on tibia–tarsus I, genu–tarsus II and distal anteroventral (*av*) seta on genu-tibia II and tibia III are short, blunt and peg-like; and posteroventral (*pv*) setae of femur and genu I-II robust with finely serrated on entire surface (Figure 3H and K). *Male:* Smaller than female (n=3, 492–558, 518); has distinctly longer sternogenital (*St1-St4*) setae, extending almost to level of second pair of setae and second-fourth pairs of sternal setae extending beyond bases of adjacent posterior setae (Figure 4C); seven pairs of setae on intercoxal IV and one pair of minute setae posterior to sternogenital plate; ventral setae on legs I-II mostly normal, setiform, and slender, however, some may be enlarged, spinelike (Figure 4D–F); large dorsal setae of tarsi III–IV coarsely barbed or serrated (Figure 4K and N); proximal anterodorsal (*ad*) seta of femur–tibia I and genu IV medium to large in size (Machado-Allison 1964; Furman 1966; Herrin and Tipton 1975; Morales-Malacara 2001).

*Nymphs:* similar to males with regard to above features, except by ontogenetic differences: Protonymph is smaller and less sclerotized than deutonymphs and adults; peritreme is short, over coxa III; four pairs of proteronotal setae, usually lack *Pn5* seta; sternal shield plate not completely developed and lacks *St4* and genital seta; anal-intercoxal plate not completely developed but smaller than in deutonymphs and male; intercoxal IV area with five pairs of setae, including adanal pair. Deutonymph female and male are smaller and less sclerotized than adults; peritreme with a long and narrow extension anteriorly; pair of proteronotal setae as adults; sternal shield plate not completely developed but *St4* and genital setae are present and off shield; anal-intercoxal plate not completely developed but smaller than in male (Deunff *et al.* 2011).

**Remarks** — This species is stenoxenous on bats of the genus *Phyllostomus* (Herrin and Tipton 1975), found here on bats *Ph. discolor* and *Ph. hastatus*. The record on *Ph. discolor* from Minas Gerais state is new to science. Individuals obtained in this study match the original description and re-descriptions (Machado-Allison 1964; Herrin and Tipton 1975; Furman 1966). This species often co-occurs with smaller *P. torrealbai* Machado-Allison, 1965a, males and nymphs of which may be misidentified as *P. acutisternus* due to the similar size, presence of some distinctly enlarged ventral setae of legs I and II, large dorsal setae of tarsi III–IV coarsely barbed or serrated; males with long sternogenital setae and intercoxal IV area bearing seven pairs of setae. *P. acutisternus*, however, has some ventral setae on legs I and II spinelike (instead of blunt and fusiform) and proximal anterodorsal (*ad*) seta of femur–tibia I and genu IV medium to large in size (instead of always small) (Herrin and Tipton 1975).

In our bGMYC species delimitation analyses (Figure 2) *P. acutisternus* is represented by three haplotypes (8, 9 and 10) out of three sequences. Haplotypes 9 and 10 were recovered as a single species with large posterior probability (pp. >95%), whereas haplotype 8 was associated with a lower posterior probability (pp. 76%).

**Differential diagnosis** — *Females*: first pair of dorsal proteronotal setae minute and on the anterolateral margin of the dorsal plate, while the other proteronotal setae large and off the plate (Figure 11C); sternal plate pear shaped (Figure 11E-F); proximal anterodorsal seta of femur II minute and proximal posterodorsal seta of femur II medium sized (Figure 11J); posteroventral (*pv*) seta of femur-tibia IV straight and bladelike (Figure 11M-N). *Male*: intercoxa IV area with eight pairs of setae, first pair of setae posterior to sternal plate short to minute; sternogenital setae long, first pair extending to or beyond level of second pair of setae (Figure 12C); proximal antero- and posterodorsal setae of femur IV long, subequal in length (Figure 12L) (Herrin and Tipton 1975). *Nymphs*: similar to males with regard to above features,
except by ontogenetic differences (Deunff *et al.* 2011) (Figure 13A–N). Deutonymph female has 13 pairs setae on intercoxal IV area, including adanal pair, and five pairs of hysteronotal setae (one pair poststigmal setae and four pairs opisthosomal setae) and plus one unpaired seta on caudal dorsum. Deutonymph male has eight pairs setae on intercoxal IV area, including adanal pair, two pairs hysteronotal setae (one pair poststigmal setae and one pair opisthosomal setae) and plus one unpaired seta on caudal dorsum (similar to adult male). Protonymph has pairs of hysteronotal setae and caudal dorsum similar to deutonymph male.

**Remarks** — This is the first record of *P. iheringi* on bats *Ar. planirostris, Ca. perspicillata, Ch. doriae* and *Pl. lineatus* from Minas Gerais. The species is oligoxenous, associated with numerous phyllostomid bats, especially with Sternodermatini bats (Herrin and Tipton 1975), and closely related to *P. ojastii* Machado-Allison, 1964. They share pronounced shoulders on the anterolateral outline of the dorsal plate and similarly shaped sternal and sternogenital plates, and posteroventral setae of femur-tibia IV are straight and bladelike in females (Herrin and Tipton 1975; Morales-Malacara 2001). They may be distinguished by the presence of a small central pair of foveae in *P. iheringi* associated with a longitudinal medial keel, the end of which is joined with the anterocentral unpaired fovea, such that it looks like an arrow (vs. absent in *P. ojastii*), *Pnl* are very small (vs. *Pnl-Pn5*). In both sexes distance between the first and second pairs is distinctly greater than that between the second and third (vs. *P. ojastii* the distance between the first and second pairs of podosomal setae is distinctly less than the distance between the second and third pairs). Morphological characters of examined specimens match original description and re-descriptions (Rudnick 1960; Herrin and Tipton 1975; Furman 1966).

In our bGMYC species delimitation analyses (Figure 2), 25 haplotypes (5, 38 to 61) out of 29 sequences from individuals morphologically assigned to *P. iheringi* were recovered split into three well supported species (pp >95%). The first putative species hereinafter referred to as *P. iheringi* A includes haplotypes 5, 46 to 61 and the second, as *P. iheringi* B, includes haplotypes 44 to 45 and third, as *P. iheringi* C includes haplotypes 38 to 45.

On other hand, the posterior probability of including all mites identified morphologically as *P. iheringi* in a single species is less than 50%, suggesting *P. iheringi* as a species complex. Interesting, when we turn to hosts: *P. iheringi* A was found on *Artibeus planirostris Artibeus lituratus* and *Carollia perspicillata*; *P. iheringi* B was found on *Artibeus planirostris* and *Art. lituratus*; and *P. iheringi* C was found on *Art. lituratus, Platyrhinus lineatus and Chiroderma doriae*. Hence, all clades of *P. iheringi* were found on *Artibeus lituratus*.

**Differential diagnosis** — *Female:* dorsal plate distinctive ornamentation with numerous small darker circular areas, some larger irregularly shaped lighter areas, and very small circular pores or setal bases. (Figure 14C); dorsal opisthosoma with six pairs of setae, first pair behind level of coxa IV rather large; next three pairs medium sized; last two pairs (posteriomost) small to minute (Figure 14D); sternal plates subpentagonal, distinctly longer than wide, with longer anterior end border that narrows abruptly, forming narrow anterior projection (Figure 14E-F); posterolateral setae of femur to tibia IV greatly inflated, with slender recurved end (Figure 14M-N). *Male:* sternogenital setae are long, the setae *St1* extending posterior to or slightly beyond the level of the first pair of pores; intercoxal IV area with seven pairs of setae plus one pairs of subterminal adanal setae; first pair posterior to sternogenital plate minute, and coxa II with setae *pv* long (length at least equal to the width of coxa II) (Herrin and Tipton 1975; Morales-Malacara 2001). *Nymphs:* similar to males with regard to above features, except by ontogenetic differences (Deunff *et al.* 2011) (Figure 16A-N). Deutonymph female has 13 pairs setae on intercoxal IV area, including adanal pair, and seven pairs of hysteronotal setae (one pair poststigma! setae and six pairs opisthosomal setae) and plus one unpaired seta on caudal dorsum. Protonymph has two pairs hysteronotal setae (one pair poststigma! setae and one pair opisthosomal setae) and plus one unpaired seta on caudal dorsum (similar to adult male).

**Remarks** — *P. paravargasi* is reported for the first time from Minas Gerais state. This species seems to be monoxenous, exclusive to *Anoura caudifer*. Examined specimens match those of the original description and re-descriptions (Herrin and Tipton 1975; Morales-Malacara 2001). In our bGMYC species delimitation analyses (Figure 2), *Periglischrus paravargasi* led to five haplotypes (31-35) out five sequences and was recovered as a single species with pp. >95%.

**Differential diagnosis** — *Female*: small, idiosoma length up to 779 µm (Figure 17A); dorsal opisthosoma with 4-5 pairs of minute setae (Figure 17D); sternal plate broadly pear shaped; five pairs of ventral body setae (metasternal setae, genital setae, and three pairs of ventral opisthosomal setae posterior to the sternal plate) expanded basally but with acute tips (Figure 17E-F); certain ventral setae of legs I and II short and spinelike to peglike in both sexes. Ventral setae on trochanters I–II, femora I–II, genua II, and one posteroventral seta of each tarsi III short, enlarged and peglike. *Setae pv* on femur-genu IV inflated and bladelike rather than setiform and recurved. *Male*: sternogenital setae long, with first pair extending well beyond level of first pair of pores and the second through fourth sternogenital setae longer, extending beyond bases of adjacent posterior setae; some setae of ventral intercoxa IV area enlarged and expanded basally; many ventral setae of legs I and II distinctly enlarged, blunt and fusiform; large dorsal setae of tarsi III–IV coarsely barbed or serrated; proximal anterodorsal (*ad*) seta of femur-tibia I and genu IV always small. *Nymphs*: similar to males with regard to above features, except by ontogenetic differences (Deunff et al. 2011) (Figure 19A–N).

**Remarks** — This is the first record of *P. torrealbai* on bats *Ph. discolor* and *T. bidens* to Minas Gerais state. This is a stenoxenous species, associated with the phyllostomine bats *Phyllostomus* and *Tonatia*, and the smallest species associated with genus *Phyllostomus* Lacépède, 1799 (the other are *P. acutisternus* and *P. grandisoma* Herrin & Tipton, 1975) (Herrin and Tipton 1975; Almeida *et al.* 2018). Morphological characters match original description and re-descriptions (Machado-Allison 1965a; Furman 1966; Herrin and Tipton 1975; Almeida *et al.* 2018).

In our bGMYC species delimitation (Figure 2), *Periglischrus torrealbai* is represented by six haplotypes (1–4 and 6–7) out of six sequences and recovered as two putative species with pp. >95%: *P. torrealbai* A (7) from *Tonatia bidens* and *P. torrealbai* B (1 to 4 and 6) from *Phyllostomus hastatus* and *Ph. discolor*. This result is in part consistent with results of Almeida *et al.* (2018), who showed that *P. torrealbai* morphology varies on a morphometric basis among the host bat species *P. discolor*, *P. hastatus* and *T. bidens* with three morphologically distinct species with host specificity, and suggests that *P. torrealbai* includes at least two distinct species of *Periglischrus*, one with *Phyllostomus* and *Tonatia* genus.

Discussion

The sequenced COI fragment provided a confident range of >10% for interspecific divergence indicates that there is sufficient genetic differentiation among species to reliably distinguish them using this molecular marker. The maximum likelihood (ML) analysis showed consistency with morphological identification of *Periglischrus* species based on descriptions, redescriptions and taxonomic keys (Machado-Allison 1964, 1965a; Furman 1966; Herrin and Tipton 1975; Morales-Malcara 2001). The nodes were supported by high bootstrap values (100%) further strengthening the confidence in the accuracy of species identification based on DNA barcoding.

Species clustering and delimitation by BINs, ASAP and bGMYC yielded distinct but partially consistent results. For ASAP analysis identified a barcode gap and supported the six species, matching the morphological identification, while BINs supported eight species, as it subdivided *P. acutisternus* and *P. torrealbai*. In contrast, bGMYC identified at least 10 putative species, as it subdivided *P. acutisternus* and *P. torrealbai* into two species each (concordant with BINs), and further subdivided *P. iheringi* into three species.

The observed subdivisions within *P. acutisternus*, *P. torrealbai*, and particularly *P. iheringi* suggest that BINs and bGMYC oversplit these species, something previously observed (Gomes-Almeida *et al.* 2023). The co-occurrence of putative species in the same locations and even on the same host allows us to discard geographic barriers as a cause for the genetic structure observed today. Instead, the observed genetic structure may be explained by past vicariance

Instead, the observed genetic structure may be explained by past vicariance
events caused by host shifts and a recent re-encounter in the case of *P. iheringi* A, B and C sampled in the same host. Nevertheless, to test these hypotheses more specimens and genes, especially nuclear genes, must be analyzed.

On a positive note, genetic barcoding has proved to be a valuable and effective tool to unravel genetic diversity and aid in the identification of *Periglischrus* mite species. Moreover, this approach has enabled reliable identification of immature stages. Notably, our study reports *Periglischrus caligus*, *P. herrerai* and *P. paravargasi* for the first time from Minas Gerais, extending their distribution ranges.

## Morphological character-based taxonomy

Herrin and Tipton (1975) assigned species to groups based mainly on sternal plate outline, size and location of the proteronotal setae, and size of proximal dorsal setae on femur I-IV. However, Morales-Malacara (2001) later added new morphological characters of the idiosoma to the type-based taxonomy of *Periglischrus*, and renamed and re-defined these species groups and subgroups. Herewith, the species recorded are classified in six species groups according to Morales-Malacara 2001.

*Periglischrus acutisternus* is a member of *acutisternus* species group, alongside with *P. tonatii* Herrin & Tipton, 1975, *P. paracutisternus* Machado-Allison & Antequera, 1971, *P. dusbabeki* Machado-Allison & Antequera, 1971, and *P. steresotrichus* Morales-Malacara & Juste, 2002 (Morales-Malacara and Juste 2002). They share female sternal plates with a distinct anterior median projection, subtriangular or elongated in shape, distinct constriction anterior to first sternal setae, and the anterolateral corners of sternogenital plate are weakly defined and long sternogenital setae (Morales-Malacara 2001). Herrin and Tipton (1975) called it subgroup B from Group I, and included *P. grandisoma* Herrin & Tipton, 1975 too. To them, the subgroup is based on the presence of a medium-sized to prominent mediodistal lobe on the palpal tibia in addition to above mentioned similarity in female sternal plate shape.

*Periglischrus torrealbai* belongs to the *torrealbai* species-group, that also comprises *P. paratorrealbai* Herrin & Tipton, 1975 and *P. eurysternus* Morales-Malacara & Juste, 2002. According to Herrin and Tipton (1975) and Morales-Malacara (2001), they share broad pear-shaped sternal plate with a somewhat narrow or broadly rounded anterior border, some enlarged ventral hysterosomal setae, proteronotal and poststigmal setae very small in females and males, and sternogenital plate with rounded lateral borders.

*Periglischrus caligus* is closely related to *P. leptosternus* Morales-Malacara & López-Ortega, 2001 from *caligus* species group (Morales-Malacara 2001). They share the dark foveae pattern on dorsal plate and a sternal plate with a subpentagonal outline and a pointed anterior border, and males with a small sternogenital plate with weakly sclerotised anterolateral borders and small sternogenital setae (Morales-Malacara 2001). Herrin and Tipton (1975) previously included *P. caligus* in subgroup A from group II (*P. paracaligus* Herrin and Tipton, 1975, *P. paravargasi* and *P. vargasi*) due to their morphological similarity (all dorsal proteronotal setae large, long, stout, with first and second pairs apart from each other by a distance larger than second and third pairs; proximal anterodorsal (ad) seta of femur–tibia I, and tibia II small to minute), and host associations (genera *Glossophoga* (*P. caligus*), *Leptonycteris* (*P. paracaligus*) and *Anoura* (*P. paravargasi* and *P. vargasi*)). Meanwhile, Morales-Malacara 2001 indicated *P. caligus* from *caligus* species group and included the other species (*P. paracaligus*, *P. paravargasi* and *P. vargasi*) from *vargasi* species-group, along with *P. empheresotrichus* Morales-Malacara, Castaño-Meneses & Klompen, 2020, and *P. calcariflexus* Morales-Malacara & López-Ortega, 2023.

*Periglischrus paravarvagi* is a member of *vargasi* species-group, along *P. vargasi*, *P. paracaligus*, *P. calcariflexus*, and *P. empheresotrichus*. The group share a sigilla or foveal arrangement, unique scale-like interfoveal ornamentation pattern on dorsal plate, long proteronotal setae and a subpentagonal sternal plate with anterior subtriangular border on female, and males sternogenital plate usually with unsclerotized anterolateral corners, with medium or
events caused by host shifts and a recent re-encounter in the case of *P. iheringi* A, B and C sampled in the same host. Nevertheless, to test these hypotheses more specimens and genes, especially nuclear genes, must be analyzed.

They share female sternal plates with a distinct anterior median projection, subtriangular or elongated in shape, distinct constriction anterior to first sternal setae, and the anterolateral corners of sternogenital plate are weakly defined and long sternogenital setae (Morales-Malacara 2001).

To them, the subgroup is based on the presence of a medium-sized to prominent mediodistal lobe on the palpal tibia in addition to above mentioned similarity in female sternal plate shape.

*Periglischrus torrealbai* belongs to the *torrealbai* species-group, that also comprises *P. paratorrealbai* Herrin & Tipton, 1975 and *P. eurysternus* Morales-Malacara & Juste, 2002. According to Herrin and Tipton (1975) and Morales-Malacara (2001), they share broad pear-shaped sternal plate with a somewhat narrow or broadly rounded anterior border, some enlarged ventral hysterosomal setae, proteronotal and poststigmal setae very small in females and males, and sternogenital plate with rounded lateral borders.

*Periglischrus caligus* is closely related to *P. leptosternus* Morales-Malacara & López-Ortega, 2001 from *caligus* species group (Morales-Malacara 2001). They share the dark foveae pattern on dorsal plate and a sternal plate with a subpentagonal outline and a pointed anterior border, and males with a small sternogenital plate with weakly sclerotised anterolateral borders and small sternogenital setae (Morales-Malacara 2001). Herrin and Tipton (1975) previously included *P. caligus* in subgroup A from group II (*P. paracaligus* Herrin and Tipton, 1975, *P. paravargasi* and *P. vargasi*) due to their morphological similarity (all dorsal proteronotal setae large, long, stout, with first and second pairs apart from each other by a distance larger than second and third pairs; proximal anterodorsal (ad) seta of femur–tibia I, and tibia II small to minute), and host associations (genera *Glossophoga* (*P. caligus*), *Leptonycteris* (*P. paracaligus*) and *Anoura* (*P. paravargasi* and *P. vargasi*)). Meanwhile, Morales-Malacara 2001 indicated *P. caligus* from *caligus* species group and included the other species (*P. paracaligus*, *P. paravargasi* and *P. vargasi*) from *vargasi* species-group, along with *P. empheresotrichus* Morales-Malacara, Castaño-Meneses & Klompen, 2020, and *P. calcariflexus* Morales-Malacara & López-Ortega, 2023.

*Periglischrus paravarvagi* is a member of *vargasi* species-group, along *P. vargasi*, *P. paracaligus*, *P. calcariflexus*, and *P. empheresotrichus*. The group share a sigilla or foveal arrangement, unique scale-like interfoveal ornamentation pattern on dorsal plate, long proteronotal setae and a subpentagonal sternal plate with anterior subtriangular border on female, and males sternogenital plate usually with unsclerotized anterolateral corners, with medium or
moderately long sized sternal setae (Morales-Malacara 2001). Additionally, this species-group
is associated with three genera of Glossophagini bats: *Anoura*, *Monophyllus*, and *Leptonycteris*
(Morales-Malacara *et al.* 2020; Morales-Malacara and López-Ortega 2023).

*Periglischrus herrerai* is a member of *hopkinsi* species-group, similar to *P. hopkinsi* Machado-Allison, 1965a in having sternal plates with a subpentagonal outline and a subtri-angular anterior border. A small cross-shaped crack on the dorsal plate occurs in males of *P. herrerai*, and both sexes of *P. hopkinsi* (Morales-Malacara 2001), and males of *P. herrerai* have a unique reticulated sternogenital shield. Furthermore, sharing the distance between *Pn1-Pn2* ≤ *Pn2-Pn3* and proximal anterodorsal (ad) setae of tibia II large (Herrin and Tipton 1975). *P. herrerai* is associated with bats of the genus *Desmodus*, while *P. hopkinsi* is associated with the Glossophagini bat *Lionycteris spurelli* and *Lonchophylla robusta* (Herrin and Tipton 1975).

*Periglischrus iheringi* belongs to *iheringi* species-group, along *P. ojastii* Machado-Allison, 1964, sharing the pronounced shoulders on anterolateral dorsal plate and sternal and sternogen-ital plates similarly shaped (Herrin and Tipton 1975; Morales-Malacara 2001). Nevertheless, *P. iheringi* females have *Pn1* minute to other setae and on dorsal plate (vs. subequal in length to the other setae and off dorsal plate), and both sexes with distances between *Pn1-Pn2* > *Pn2-Pn3* (vs. *Pn1-Pn2* < *Pn2-Pn3*) (Herrin and Tipton 1975). Herrin and Tipton (1975) also grouped these two species (their group III), along with *P. ramirezi* Machado-Allison & Antequera, 1971, based on the shape of the sternal plate (especially *P. ojastii* and *P. iheringi*) and males with 7-8 pairs of setae on intercoxal area IV and sternogenital setae longer, *St1* seta extending posteriorly to or beyond level *St2* setae bases or just beyond first pair of pores. On the other hand, Morales-Malacara (2001) categorized *P. ramirezi* from *delfinadoae* species-group, along with *P. delfinadoae* Dusbábek, 1967, still belonging to *acutisternus*-clade. This placement occurred despite limited morphological similarities and its association with a different bat clade. *P. delfinadoae* is associated to stenodermatini bats and *P. ramirezi* to macrotine bats.

Herrin and Tipton (1975) also grouped these two species (their group III), along with *P. ramirezi* Machado-Allison & Antequera, 1971, based on the shape of the sternal plate (especially *P. ojastii* and *P. iheringi*) and males with 7-8 pairs of setae on intercoxal area IV and sternogenital setae longer, *St1* seta extending posteriorly to or beyond level *St2* setae bases or just beyond first pair of pores. On the other hand, Morales-Malacara (2001) categorized *P. ramirezi* from *delfinadoae* species-group, along with *P. delfinadoae* Dusbábek, 1967, still belonging to *acutisternus*-clade. This placement occurred despite limited morphological similarities and its association with a different bat clade. *P. delfinadoae* is associated to stenodermatini bats and *P. ramirezi* to macrotine bats.
