Optimizing Decellularization of Bovine Ovarian Tissue: Toward a Transplantable Artificial Ovary Scaffold with Minimized Residual Toxicity and Preserved Extracellular Matrix Morphology
Authors: León-Félix Cecibel M. , Maranhão Andrea Q. , Amorim Christiani A. , Lucci Carolina M.
Published: March 2024

Introduction: The decellularized extracellular matrix (dECM) from ovarian tissue could be the best scaffold for the development of a transplantable artificial ovary. Typically, dECM from ovarian tissue has been obtained using sodium dodecyl sulfate (SDS), at a concentration of 1% for 24 h. However, SDS can leave residues in the tissue, which may be toxic to the seeded cells. This study aimed to obtain dECM from bovine ovarian tissue using SDS and NaOH at a minimum concentration in the shortest incubation time. Methods: The respective SDS and NaOH concentrations investigated were 1% and 0.2 m; 0.5% and 0.1 m; 0.1% and 0.02 m; and 0.05% and 0.01 m, with 24-, 12-, and 6-h incubation periods. After the incubation time, the tissue was washed in 50 mL of distilled water for 6 h. Results: Histological analysis confirmed decellularization and showed the conservation of collagen fibers in all samples following treatment. Furthermore, the lowest SDS and NaOH concentrations that showed no DNA remaining during electrophoresis analysis were 0.1% and 0.02 m when incubated for 24 and 12 h. DNA quantification resulted in <0.2 ng DNA/mg ovarian tissue using these protocols. Additionally, the coculture of dECM (obtained by 0.1% SDS and 0.02 m NaOH for 12 h) with ovarian cells showed that there was no toxic effect for the cells for up to 72 h. Conclusion: The protocol involving 0.1% SDS and 0.02 m NaOH for 12-h incubation decellularizes bovine ovarian tissue, generating a dECM that preserves the native ECM morphology and is nontoxic to ovarian cells.
Melanocytic Nevus of the Superior Conjunctival Fornix: A Case Report
Authors: Adetunji Modupe O. , Cummings Thomas J. , Materin Miguel A. , Maniar Arpita S.
Published: March 2024

Introduction: Conjunctival nevi are benign tumors that are commonly located at the nasal or temporal limbus and rarely in the fornix or tarsus. We report a case of a patient presenting with a solitary compound cystic nevus of the conjunctival fornix in the background of bilateral complexion-associated melanosis. Case Presentation: A 71-year-old African-American female was referred for evaluation of an incidentally noted melanocytic lesion of the right conjunctival fornix. The patient underwent an excisional biopsy, revealing histological features consistent with a compound cystic nevus. Conclusion: This finding is noteworthy due to the rarity of conjunctival nevi originating in the fornix. The case underscores the importance of excisional biopsy in evaluating conjunctival forniceal melanocytic lesions to exclude malignant melanoma, a critical consideration for prognosis.
Corpo e experiência histórico-social no cinema brasileiro (2014-2021)
Authors: Costa Júnior Edson Pereira da
Published: March 2024

O artigo argumenta que certo cinema brasileiro independente (2014-2021) investe na mediação somática da experiência histórico-social. Observa-se que filmes realizados ou protagonizados por sujeitos alvos de desigualdades de raça, classe e gênero mobilizam o corpo em duas frentes. De um lado, como signo cumulativo de processos de determinação dos sujeitos. De outro, como matriz de resistências produzidas por experiências performadas, seja nas epistemes que transmitem, seja nas identidades que deslocam. O duplo atributo político é discutido a partir das análises de O verbo se fez carne (2019), de Ziel Karapotó, e Vaga carne (2019), de Grace Passô e Ricardo Alves Jr.
Associations of Circulating Vascular Cell Adhesion Molecule‐1 and Intercellular Adhesion Molecule‐1 With Long‐Term Cardiac Function

Published: March 2024

Background

Although VCAM‐1 (vascular cell adhesion molecule‐1) and ICAM‐1 (intercellular adhesion molecule‐1) have been associated with incident heart failure with preserved ejection fraction (HFpEF) and atrial fibrillation (AF), the associations of VCAM‐1 and ICAM‐1 with sensitive measures of cardiac structure/function are unclear. The objective of this study is to evaluate associations between VCAM‐1, ICAM‐1, and measures of cardiac structure and function as potential pathways through which cellular adhesion molecules promote HFpEF and AF risk.

Methods and Results

In MESA (Multi‐Ethnic Study of Atherosclerosis), we evaluated the associations of circulating VCAM‐1 and ICAM‐1 at examination 2 (2002–2004) with measures of cardiac structure/function on cardiac magnetic resonance imaging at examination 5 (2010–2011) after multivariable adjustment. Mediation analysis of left atrial (LA) strain on the association between VCAM‐1 or ICAM‐1 and AF or HFpEF was also performed. Overall, 2304 individuals (63±10 years; 47% men) with VCAM‐1 or ICAM‐1, cardiac magnetic resonance imaging, and covariate data were included in analysis. Higher VCAM‐1 and ICAM‐1 were associated with lower LA peak longitudinal strain and worse global circumferential left ventricular strain but were not associated with left ventricular myocardial scar or interstitial fibrosis. Lower LA peak longitudinal strain mediated 8% (95% CI, 2–30) of the relationship between VCAM‐1 and HFpEF and 9% (95% CI, 2–21) of the relationship between VCAM‐1 and AF.

Conclusions

Higher VCAM‐1 and ICAM‐1 were associated with lower LA function and left ventricular systolic function but were not associated with myocardial scar or interstitial fibrosis. VCAM‐1 and ICAM‐1 may promote HFpEF and AF risk through impaired LA reservoir function.
Urban Transit Infrastructure and Inequality
Authors: Lee Kwok Hao , Tan Brandon Joel
Published: March 2024

We propose a quantitative spatial model featuring heterogeneous worker groups and their travel to consume non-tradable goods and services. We consider the opening of the Downtown Line (DTL) in Singapore, which connected regions where high-income households have residential amenities to where non-traded sectors are productive. Leveraging transit farecard data, we show that high-income workers saw large welfare gains but low-income workers gained little. Everyone enjoyed improved access to consumption opportunities, but low-income jobs in non-tradables moved to less attractive workplaces. Abstracting from consumption travel understates the disparate impact across worker groups three-fold.
Parkinsonia aculeata L. recorded as alien species in natural habitats of Egypt: Potential for naturalization, invasion or utilization!
Authors: HALMY MARWA WASEEM A. , YASIEN ASMAA AHMED , SHEDED MOHAMED GABR
Published: March 2024

Parkinsonia aculeata L. is native to South America and was recorded for the first time in Egypt in the wild. It was recorded in vegetation survey of Elephantine Island in Aswan Governorate in 2020, then it was recorded in Dakhla Oasis in the Western Desert in 2023. The species identity was confirmed by a comparative macromorphological study between the collected specimens and herbarium specimens from other countries, and live specimens cultivated in Antoniades Botanic Garden in Alexandria. The occurrence of this species in the natural habitats of Egypt represents an important disjunction of the biogeographic relevance and raises concerns. The species may cause negative impacts to native species, outcompeting species of the same functional group, or can increase fire hazards in the invaded areas. Taking into consideration that the species has already been naturalized in some countries, its further expansion in Egypt is a possibility. It is of great concern to monitor and control the spread of the species in Egypt and possibly promote an early eradication. Notes on the habitat in which the species has been recorded and its invasive status in Egypt and surrounding nations are discussed.

A taxonomic review of the genus Myrmelachista (Hymenoptera: Formicidae) in Costa Rica
Authors: LONGINO JOHN T.
Published: March 2024

The Costa Rican fauna of the genus Myrmelachista is reviewed. Myrmelachista is a poorly-known lineage of Neotropical arboreal ants. Although a few are conspicuous surface foragers, the majority have cryptic habits, nesting in live stems of plants and rarely foraging on the surface. Fourteen species are reported, of which the following ten are described as new: M. flavocotea, flavoguarea, haberi, joycei, lauroatlantica, lauropacifica, longiceps, meganaranja, nigrocotea, and osa. Myrmelachista costaricensis Wheeler is synonymized under M. plebecula Menozzi, and M. zeledoni thiemi is synonymized under zeledoni. The enigmatic M. cooperi, previously known from a single alate queen, is rediscovered and the worker and male described. Keys to workers, queens, and males are provided. Myrmelachista species have either 9 or 10-segmented antennae, with most of the 9-segmented forms concentrated in Central America and the Caribbean, and the 10segmented forms concentrated in South America. The taxonomic status of all the 9-segmented forms is discussed.
A new species of the genus Centrolene (Amphibia: Anura: Centrolenidae) from Ecuador with comments on the taxonomy and biogeography of Glassfrogs
Authors: CISNEROS-HEREDIA DIEGO F. , MCDIARMID ROY W.
Published: March 2024

We describe a new species of Glassfrog, Centrolene mariaelenae n. sp., from the Contrafuerte de Tzunantza, southeastern Ecuador. The new species is assigned to the Centrolene gorzulai species group, a clade previously known only from the Guayana Shield region, because the parietal peritoneum is transparent and the hepatic peritoneum is covered by guanophores. We analyze the diversity patterns of Glassfrogs from eastern Ecuador. The distribution of the new species herein described supports previous hypothesis of a biogeographical connection between the Andes and the Guayana Shield for various groups of plants and animals; particularly a relationship between the Guayana Shield and the sandstone outcrops mountain ranges of southeastern Ecuador and northeastern Peru. We also comment on the infrageneric and generic classification of Glassfrogs, and propose the new combinations Centrolene balionotum n. comb., Cochranella antisthenesi n. comb., and Cochranella pulverata n. comb.

Authors: TAKIYA DANIELA M. , CAVICHIOLI RODNEY R. , MCKAMEY STUART H.
Published: March 2024

Four species of the sharpshooter genus Homalodisca Stål are known to occur in Brazil: H. ignota Melichar; H. ignorata Melichar; H. lucernaria (Linnaeus), a senior synonym of the type-species Cicada triangularis Fabricius; and the new species H. spottii sp. nov. described from Bahia and Sergipe states. H. spottii sp. nov. is probably involved in the transmission of Citrus variegated chlorosis in Northeastern Brazil and is easily distinguished from other Homalodisca species by the (1) dark dorsum mottled with yellow; (2) contrasting yellow mesoscutellum; (3) broadly concave female sternite VII; and (4) aedeagal atrium not expanded dorsally and with 2 pairs of straight spiniform processes. Males and the female genitalia of H. ignota are described and illustrated for the first time (including an undistorted view of the female sternite VII). A sclerotized female internal sternite VIII in H. ignota and H. spottii sp. nov. is newly recorded for this genus. Homalodisca species are newly recorded for following Brazilian states: H. ignota from Rio de Janeiro and São Paulo; H. ignorata from Minas Gerais, Paraná, Rio de Janeiro, and Santa Catarina; and H. lucernaria from Pará and Roraima. A taxonomic key and notes on Brazilian species are also given.

The saproxylic beetles in the families Mycteridae, Boridae, Pythidae, Pyrochroidae, and Salpingidae of the Maritime Provinces of Canada are surveyed and new provincial records are reported. Boros unicolor Say is newly recorded in New Brunswick, Nova Scotia, and Atlantic Canada as a whole; Pytho niger Kirby and Rhinosimus viridiaeneus Randall are newly recorded in New Brunswick; Neopyrochroa femoralis (LeConte) is newly recorded in Nova Scotia; and Priognathus monilicornis (Randall), Pedilus lugubris (Say), Dendroides canadensis Latreille, and Dendroides concolor (Newman) are all newly recorded in Prince Edward Island. The distribution and bionomics of all 15 species known from the region are briefly summarized. The composition of the region’s fauna is discussed, particularly in the context of saproxylic beetles and the effects of forest management practices on this group of insects.
Staphylinidae (Insecta: Coleoptera) of the Biologia Centrali-Americana: Current status of the names
Authors: NAVARRETE-HEREDIA JOSÉ LUIS , GÓMEZ-RODRÍGUEZ CECILIA , NEWTON ALFRED F.
Published: March 2024

The Biologia Centrali-Americana (1879–1915), an obligate reference for the taxonomy of insects and other organisms from Mexico and Central America, is now available free on the web at http://www.sil.si.edu/digitalcollections/bca/. However, many included names are now out of date. We provide an updated list of all names of Staphylinidae (including Pselaphidae and Scaphidiidae) cited in the Biologia Centrali-Americana to use as a complement to that work. Of the 1610 staphylinid species-group names originally included, 929 remain as valid names without change, 581 have been previously transferred to other genera, 125 have been treated as junior synonyms, four treated as misidentifications of other names, and one (Cephaloplectus godmani Sharp, 1883) has been transferred to the family Ptiliidae. Our study also shows that 38 additional names should be transferred as new combinations to the genera Achenomorphus (from Aderocharis), Biocrypta and Homaeotarsus (from Ochthephilum), Neohypnus (from Xantholinus), and Platydracus (from Staphylinus and Amichorus), and seven species previously transferred to Medon should be returned to their original genus Scioporus as resurrected combinations.

Evidence for cryptic species in the tadpole shrimp Triops granarius (Lucas, 1864) (Crustacea: Notostraca)
Authors: KORN MICHAEL , HUNDSDOERFER ANNA K.
Published: March 2024

We used three ribosomal DNA markers to investigate the genetic divergence of Triops granarius (Lucas, 1864) populations from Tunisia, Namibia and Japan. The comparison of the genetic distances between these samples and those found among other species of Notostraca (both Triops and Lepidurus) strongly suggests that the three Triops granarius populations investigated belong to different, possibly cryptic species.

Systematic notes on tribes in the family Caliscelidae (Hemiptera: Fulgoroidea) with the description of new taxa from Palaearctic and Oriental Regions
Authors: GNEZDILOV VLADIMIR M. , WILSON MICHAEL R.
Published: March 2024

A diagnosis of the family Caliscelidae Amyot et Serville, 1843 is given. The system of higher taxa of the family is revised. The genus Coinquenda Distant, 1916 is transferred to the subfamily Ommatidiotinae from the family Issidae. Coinquendini trib. nov. (type genus: Coinquenda Distant, 1916) is erected in the subfamily Ommatidiotinae. Coinquenda nigroclavata Distant, 1916 is redescribed. The tribe Adenissini Dlabola, 1980 is recharacterized and transferred to the subfamily Ommatidiotinae from the subfamily Caliscelinae. The rank of the tribe Bocrini Emeljanov, 1999 is reduced to the subtribe of the tribe Adenissini. As a result the genera Perissana Metcalf, 1952, Pterilia Stål, 1859, and Pterygoma Melichar, 1903 are transferred to the Adenissini from the family Issidae. Pteriliina subtrib. nov. (type genus: Pterilia Stål, 1859) is erected in the tribe Adenissini. Distantina gen. nov. (type species: Elidiptera fimlivata Walker, 1851) is erected in the subtribe Pteriliina subtrib. nov. Keys to the subfamilies, tribes, and subtribes of the Caliscelidae, the genera of the tribe Adenissini, and species of the genus Perissana Metcalf are given. Anissus Dlabola, 1980 and Denissus Dlabola, 1980 are placed in synonymy under Perissana Metcalf, 1952. Perissana jakowleffi (Puton, 1890) is redescribed. Adenissus circularis Dlabola, 1980 and Anissus bispinatus Dlabola, 1980 are transferred to the genus Perissana. Perissana dlabolai nom. nov. is proposed as a replacement name for Adenissus circularis Dlabola, 1980 (secondary homonym). Raunolina subgen. nov. (type species: Perissus circularis Linnavuori, 1952) is erected in the genus Perissana. Perissana (Raunolina) arabica sp. nov. is described from Saudi Arabia. 5 th instar larva of Adenissus riadicus Dlabola, 1985 is described. New faunistic records for 5 species of the family are provided.
Redescription of the largest ice bug, Namkungia magnus com. nov. (Grylloblattodea, Grylloblattidae) from Korea

The largest ice bug species, Namkungia magnus (Namkung, 1986) from Balgudeuk cave at Jeongseon, Gangwon-do, Korea is transferred from the genus Galloisiana and redescribed with setae and trichobothria patterns, and with mouthpart, basisternum and genital structure descriptions based on the morphological characters. This species resembles N. biyongensis (Namkung, 1974) by its large size (longer than 30 mm), eyeless condition, more than 47antennomeres, and 12 cercomeres but is distinguished by asymmetrical supra-anal plate of the bulging 9th abdominal tergite with truncate projection, 52 antennomeres, the cervical sclerite with nine setae (11 on right) on the lateral margin of the left, and copulatory sclerites of the genital structure.
Chironomid midges from early Eocene amber of France (Diptera: Chironomidae)
Authors: DOITTEAU GAELLE , NEL ANDRÉ
Published: March 2024

The Basal Eocene Oise amber has provided a rich and diverse chironomid fauna of 30 recognised species, with a general taxonomic pattern similar to that of the modern fauna. Among these fossils, 19 species are described in 17 recent genera, and 7 are attributed to 6 extinct new genera; thus, only 22% of the genera are not recent. All species belong to recent subfamilies, and the great majority to recent genera. We provide paleoenvironmental and paleoclimatic inferences, based on analyses at both the subfamily and generic levels. The subfamily analysis was conducted with 841 specimens, and revealed 14.9% Tanypodinae, 23.7% Chironominae, 0.4% Prodiamesinae, 0.3% Diamesinae, and 60.3% Orthocladiinae. The Chironominae are a minority in this fauna, but probably not because of climatic constraints. This subfamily was probably absent in the Upper Cretaceous and still under diversification during the Early Paleogene. Our generic inferences are congruent with available palaeoclimatic and palaeoecological reconstructions. They provide an image of a sandy, backwater fluvial deposit under a warm climate.

A total of 10 species are studied, including Trechus isabelae n. sp., collected in a volcanic pit on São Jorge, one of the nine islands of the Azores. This new Trechus species represents the eighth species of Trechinae described from the underground environment of the Azores. An identification key for the Azorean species of Trechus is provided along with additional information per species on their distribution and conservation status in the archipelago. Possible reasons for the different degrees of adaptation to the conditions of the underground environment exhibited by Trechinae are also discussed.
A new species of Ptomaphagus (Appadelopsis) (Coleoptera: Leiodidae) from Great Smoky Mountains National Park, U.S.A.
Authors: TISHECHKIN ALEXEY K.
Published: March 2024

Recent activities within the beetle component of the Great Smoky Mountains National Park (GSMNP) All-Taxa Biodiversity Inventory (ATBI) include a substantial collecting effort (Carlton & Bayless in press). Sampling of forest litter-dwelling beetles is an important part of this collecting program, and substantial numbers (217 by the end of 2006) of samples from GSMNP and vicinity has been processed since 2001. The progress of sorting and identification of this material varies depending on taxon, but several new species have been discovered and described (e.g., Konstantinov & Tishechkin 2004; Sokolov et al. 2004; Gimmel & Ślipiński 2007). This paper is the first taxonomic treatment of the genus Ptomaphagus Illiger, 1798 subgenus Appadelopsis Gnaspini, 1996, of the Great Smokies.
Megalyra baltica Poinar and Shaw n. sp. (Hymenoptera: Megalyridae), a long-tailed wasp from Baltic amber
Authors: POINAR GEORGE , SHAW SCOTT RICHARD
Published: March 2024

The wasp family Megalyridae includes eight living genera of presumed idiobiont ectoparasitoids, most of which are associated with relict primary tropical forests (Shaw 1990b, 2006). Their biology is poorly known except for a few species. Their behavior and host range appear to be diverse since one Australian species, Megalyra fasciipennis Westwood, parasitizes cerambycid beetle larvae in wood, while the much smaller Australian M. troglodytes Naumann parasitizes sphecid wasp larvae in mud nests on vertical rock faces (Shaw 1990a). The long ovipositor of many Megalyra species, as well as the phylogenetic analysis of Shaw (1990b), suggests that parasitism of immature wood-boring beetles is the ancestral and more generalized behavior for the genus. It is presumed that ancient megalyrids, like many of their modern descendants, would have been attracted to dead and dying beetle-infested trees, where they might become trapped in sap flows, and eventually fossilized as amber inclusions.

Description of three new species of the genus Chromaphyosemion Radda, 1971 (Cyprinodontiformes: Nothobranchiidae) from the coastal plains of Cameroon with a preliminary review of the Chromaphyosemion splendopleure complex
Authors: SONNENBERG RAINER
Published: March 2024

Three new species of the genus Chromaphyosemion Radda, 1971 are described from the coastal plains of Cameroon. They are distinguished from the phylogenetically and geographically close congeneric species through diagnostic characters of male color patterns. Some remarks on recently described species are made and a phylogenetic hypothesis of all currently known described species and all but two undescribed forms of the genus Chromaphyosemion based on mitochondrial DNA sequences is given. The molecular data support the monophyly of this genus as previously stated on the basis of morphological data and allow a review of the Chromaphyosemion splendopleure complex, a taxonomically confusing group. All newly described species are endemic to Cameroon, contributing to the high diversity and endemicity of the nothobranchiids in this country.
The Dyobelba tectopediosa species-group (Acari: Oribatida: Damaeidae) from the Southeastern USA, with a key to world species of Dyobelba and notes on their distribution
Authors: BAYARTOGTOKH BADAMDORJ , NORTON ROY A.
Published: March 2024

Species of the small oribatid mite genus Dyobelba (Damaeidae) mostly inhabit forest litter in the Northern Hemisphere. Herein we redescribe Dyobelba tectopediosa Jacot and propose four related species (D. behanae sp. nov., D. crossleyi sp. nov., D. dindali sp. nov. and D. granulata sp. nov.) that form an apparently monophyletic group characterized by unusual alveolate sculpturing on the prodorsum. Members of this group inhabit various forest types in the southeastern USA, particularly in the southern Appalachian Mountains. Descriptions are based only on adults, except all instars are described for D. dindali, including the full ontogeny of leg setation, using material from a laboratory culture. A diagnostic key to adults of the 11 known species of Dyobelba is given, along with summaries of their geographical and ecological distributions.
Pseudrotasfer microincubator gen. et spec. nov., a brooding cucumariid holothurian (Echinodermata: Holothuroidea: Dendrochirotida) from the Burdwood Bank (south-western Atlantic Ocean)

A new brooding cucumariid holothurian, Pseudrotasfer microincubator gen. et sp. nov. has been discovered in samples taken by the LAMPOS expedition with FS “Polarstern” at Burdwood Bank in the south-western Atlantic Ocean. This species is characterised by peculiar wheel-like baskets in its outer body wall and a deeper layer of simple large perforated plates, that require the establishment of a new genus. The new genus and species are characterised, and a description is provided of its external and internal morphology, including a SEM study of its ossicles.
Description of two new species of Rhinella (Anura: Bufonidae) from the lowlands of the Guiana shield
Authors: FOUQUET ANTOINE , GAUCHER PHILIPPE , BLANC MICHEL , VELEZ-RODRIGUEZ CLAUDIA M.
Published: March 2024

The Rhinella margaritifera complex is characterisized by the presence of many cryptic species throughout its wide distribution, ranging from Panama to Bolivia and almost entire Amazonia. French Guiana has long been thought to harbor two species of this group (Rhinella margaritifera and one unnamed species), though a recent survey using molecular data indicated as many as five lineages. At least three of these lineages do not appear to interbreed despite broad sympatry and thus could be easily regarded as distinct species according to both the biological and phylogenetic species concepts. We examined morphological variation of four of these lineages, along with acoustic data to determine whether these characters discriminate these goups. These analyses, combined with published data of other Rhinella species, indicated that two of these lineages represent previously unnamed species. Two of the remainings are allocable to R. margaritifera while the status of the fifth is still unclear because so far it is morphologically indistinguishable from R. castaneotica.
Polystoma floridana n. sp. (Monogenea: Polystomatidae) a parasite in the green tree frog, Hyla cinerea (Schneider), of North America
Authors: DU PREEZ LOUIS H. , VERNEAU OLIVIER , GROSS TIMOTHY S.
Published: March 2024

Polystoma floridana is described as a new species of the Polystomatidae parasitic in the urinary bladder of Hyla cinerea in Gainesville, Florida, USA. This is the fifth polystome from an anuran host described from North America but only the third belonging to the genus Polystoma. Here we show that the parasite from H. cinerea is a separate species. It is distinguished from other American Polystoma species by a combination of characters including body size, haptor length, body rations, size and shape of hamuli and marginal hooklets. In a sample of 235 frogs, 13.6% were infected with up to four parasites per host (mean intensity 1.6).
Morphological development of Hypophthalmus fimbriatus and H. marginatus post-yolk-sac larvae (Siluriformes: Pimelodidae)
Authors: DE OLIVEIRA EDINBERGH CALDAS , BIALETZKI ANDRÉA , ASSAKAWA LUCIANA FUGIMOTO
Published: March 2024

Descriptions of stages in the larval development of two sympatric and congeneric freshwater fishes from the rio Negro (Amazon basin), Hypophthalmus fimbriatus and H. marginatus, are presented. Larval development is described in terms of ontogenetic changes in morphology, pigmentation and fin development. Developmental changes during the larval period of the two species are similar, but they can be separated mainly by the following variables: eye diameter, head width, body depth and pre-pectoral distance. Aspects of their reproduction strategies are also discussed.
Dupliciporia lanterna n. sp. (Digenea: Zoogonidae) from Priacanthus hamrur (Perciformes: Priacanthidae) and additional zoogonids parasitizing fishes from the waters off New Caledonia
Authors: BRAY RODNEY A. , JUSTINE JEAN-LOU
Published: March 2024

The genus Dupliciporia is considered valid based on observation of the type species, and is considered the senior synonym of Parasteganoderma and Liliaoralis. The new combinations Dupliciporia cephaloporum (Machida & Araki, 1990) and Dupliciporia cataluphi (Korotaeva, 1994) are formed. A new species, Dupliciporia lanterna, is described from the digestive tract of Priacanthus hamrur from the waters off New Caledonia, South Pacific. Dupliciporia lanterna n. sp. differs from its congeners in its elongate body and its rectilinear vitelline fields. Dupliciporia sp. (=Parastegano- derma sp. of El-Labadi et al. [2006]) from Pristigenys niphonia from the Gulf of Aqaba, is briefly described and figured. Other zoogonids reported from New Caledonian waters are Zoogonus pagrosomi from Lethrinus atkinsoni and Lethrinus genivittatus, Parvipyrum acanthuri from Acanthurus blochii, Deretrema combesae and D. combesorum from Parupeneus multifasciatus and Lecithostaphylus nitens from Tylosurus crocodilus.
DNA barcoding of new world cicada killers (Hymenoptera: Crabronidae)

Published: March 2024

We are engaged in a comprehensive study of cicada killers (Sphecius spp.), including their behavioral ecology. At one location, we observed interactions among three putative species of Sphecius, and used DNA barcoding to help clarify relationships among them. For this, we sequenced a fragment of the mitochondrial cytochrome c oxidase subunit I gene. During our study, a new taxonomic key of New World cicada killers, based on morphology, was published, and we expanded the barcoding project to test the congruence between barcodes and this key. In general, barcoding evidence supports morphological distinctions among species; sequence divergences between individuals of different species were within the range expected for congeneric Hymenoptera. However, two conflicts between barcoding and morphological evidence were noted. 1) Haplotypes of Sphecius grandis Say fall into two highly divergent clades, suggesting they are cryptic species. 2) Two clades of S. convallis Patton were found, and the sequences of one clade are virtually identical to those of S. speciosus Drury, suggesting that this clade of S. convallis is conspecific with S. speciosus. Alternative explanations are possible for this result, including hybridization and introgression between the two species. We conclude that our DNA barcoding evidence should be interpreted with caution, but that it has generated interesting questions we hope to resolve with field research coupled with analysis of suitable nuclear gene sequences.

Published: March 2024

The genus Odontophrynus is endemic to South America and currently consists of 10 recognized species distributed in southern and eastern of the continent (Rosset et al. 2006; Rosset 2008; Amaro et al. 2009). The americanus group is currently represented by four species: O. americanus, O. lavillai, O. cordobae and O. maisuma. Odontophrynus cordobae is cryptic with their polyploid counterpart O. americanus and inhabited in the center and northwestern Córdoba and south of Santiago del Estero provinces (Martino and Sinsch 2002; Rosset et al. 2006). The tadpole of O. cordobae remains undescribed. Herein we describe the larval external morphology and oral disc.

Authors: BEZDĚK JAN
Published: March 2024

Species of the genus Mimastra Baly, 1865 (Coleoptera: Chrysomelidae) with discoid (M. oblonga group) and trapezoid (M. tarsalis group) protarsomere in males are revised. Mimastra oblonga group comprises 7 valid species: M. oblonga (Gyllenhal, 1808) comb. nov.; M. cyanura (Hope, 1831); M. lunata (Kollar & Redtenbacher, 1844); M. soreli Baly, 1878; M. latimana Allard, 1889; M. guerryi Laboissière, 1929 and M. anicka sp. nov. (Thailand and Myanmar); while M. tarsalis group includes only one species—M. tarsalis Medvedev, 2009. The primary types of almost all relevant taxa were examined. Galleruca oblonga Gyllenhal, 1808, listed for many years in the genus Aulacophora, is transferred to Mimastra. Status restored for four species (M. lunata, M. soreli, M. latimana and M. guerryi), often listed as synonyms of M. cyanura. Mimastra apicalis Baly, 1886 is a new junior synonym of M. lunata (Mimastra apicalis Baly syn. nov.) and M. quadrivittata Mader, 1938 is confirmed as a synonym of M. guerryi. Lectotypes are designated for Galleruca oblonga, Mimastra cyanura, M. lunata, M. apicalis and M. soreli. The syntype series of M. soreli consists of a mixture of two species. Its identity is fixed for the species from Sichuan. The second part of the syntype series refers to M. oblonga. Male protarsus, protibia and male and female genitalia of all the species are illustrated and key to the species is given.

Although the subfamily Nemobiinae presents a cosmopolitan distribution, with seven genera occurring in Brazil, being five species in the southeastern region, no species of this subfamily had been described for the State of Minas Gerais. In this work we describe two new species in Phoremia (Phoremia zefai sp. nov. and Phoremia rolfsi sp. nov.) and one of Zucchiella (Zucchiella matiottiae sp. nov.), found in Atlantic Forest remnants of Minas Gerais. We present a key for Brazilian Phoremia and Zucchiella species, with complete illustrations of genitalic morphological characters used in the key. Together with descriptions of the three new species, we also present distribution map, photographs of the types, illustrations of female terminalia and comparative illustrations of male genitalia from all known Brazilian species.

Published: March 2024

We describe a new species of small rhacophorid frog from north central Vietnam. Gracixalus quangi sp. nov. is morphologically and genetically most similar to G. gracilipes and G. supercornutus, but is distinguished from these species and all other rhacophorids in Vietnam and adjoining countries by a combination of their small size (males Gracixalus quangi sp. nov. has a non-stereotypical, hyperextended vocal repertoire, with calls highly variable in structure, duration, amplitude and frequency (dominant frequency 4.1–4.7 kHz). Like G. gracilipes and G. supercornutus, G. quangi sp. nov. deposits egg clutches in clumps on leaves overhanging shallow forest pools or puddles. The new species is known from montane evergreen forest in Pu Hoat Proposed Nature Reserve in western Nghe An Province, between ~600–1,300 m elevation. Preliminary molecular (mtDNA) data recovered two strongly supported clades within frogs currently considered to belong to genus Gracixalus, with the new species nested within a monophyletic clade consisting of G. gracilipes, G. supercornutus, and G. quyeti.
