## Original research

### ABSTRACT

The Tenuipalpidae family includes globally distributed plant-feeding mites of economic concern due to their potential as phytopathogen vectors and their role in damaging ornamental and agricultural plants. This study presents a faunistic survey of flat mites across Slovakia and Ukraine, in addition to complementary data from the Netherlands, Hungary, and Bulgaria via U.S. interception records. Field collections in Slovakia and Ukraine yielded 13 tenuipalpid species across three genera, with several new national and continental records, including four *Pentamerismus* species recorded for the first time in Europe. New host plant associations, particularly involving coniferous and ornamental taxa, were frequently documented. These findings expand the known distribution of flat mites in Central and Eastern Europe and underscore the importance of targeted faunistic surveys for understanding species diversity, host range, and potential pathways of introduction. The integration of systematic field sampling, literature reviews, and interception data supports early detection and regulatory measures critical for plant protection and biosecurity programs.

### Introduction

The Tenuipalpidae family Berlese comprises over 1,100 described species of plant-feeding mites with a global distribution (Castro *et al.* 2025). These mites are of increasing concern in agriculture and ornamental horticulture due to their ability to damage plant tissues and to vector plant viruses (de Lillo *et al.* 2021; Ramos-Gonzalez *et al.* 2023). Understanding their diversity, distribution, and host range is fundamental for plant protection and biosecurity. In this context, faunistic surveys play a critical role in uncovering mite biodiversity, detecting invasive species, and guiding pest risk assessments.

Comprehensive faunistic surveys based on systematic sampling, accurate identifications, and host plant documentation are essential for establishing baseline data in regions where the acarofauna remains poorly known. Surveys address major knowledge gaps in mite distribution, which is critical for effective pest surveillance and biosecurity, especially in regions where agricultural trade is expanding and baseline faunistic data are limited, such as

Central and Eastern Europe. Although some records originate from taxonomic revisions or port-of-entry interceptions rather than targeted field surveys, they highlight the necessity of reliable identifications for quarantine decision-making and regulatory enforcement.

Tenuipalpid systematics remain complex, with many species exhibiting cryptic diversity and unresolved species complexes, requiring expert morphological and molecular approaches (Navia et al. 2013; Beard et al. 2015). New faunistic records are important in this context, as they help clarify species distributions, inform ecological studies, and support regulatory frameworks for pest management (Hoy 2011).

The online databases on the Tenuipalpidae family by Castro *et al.* (2025), compile faunistic data from the literature, and bring evidences of geographic gaps in knowledge, particularly across Central and Eastern Europe. Several countries, including Slovakia and the Czech Republic, have no documented records of Tenuipalpidae, while others, including Bulgaria (4 records from 1876–1949), Hungary (22 records from 1867–2018), Ukraine (32 records from 1876–1983), and the Netherlands (9 records from 1867–1972), lack recent survey efforts and remain underrepresented in regional syntheses (Kontschán and Ripka 2017; Zhovnerchuk *et al.* 2021).

This study presents new faunistic data from Slovakia and Ukraine, derived from systematic field sampling of diverse host plants. It also incorporates previously unpublished interception records from the United States to document tenuipalpid species associated with plant imports from Bulgaria, Hungary, and the Netherlands. By combining targeted fieldwork with archival and interception data, this study contributes to a broader understanding of the tenuipalpid fauna in Central and Eastern Europe. It also highlights the importance of faunistic surveys as a foundational tool for acarological research and highlights the critical role of agricultural trade interceptions in biosecurity decision-making.

# Materials and methods

## Samplings in Slovakia and Ukraine

Samplings were conducted across Slovakia and Ukraine's urban and natural ecosystems by the first author (Table 1; Figure 1). In Slovakia, mite samples were collected between 2023 and 2024, primarily from April to October, with additional sampling in February 2024. Surveys were carried out across 10 different cities and two national parks, examining a total of 85 samples from over 30 species of host plants. In Ukraine, sampling took place from July to October 2024 in two botanical gardens in Kyiv. A total of 26 samples were collected from 20 species of host plants, predominantly introduced conifers.

## Mite extraction, preservation, and identification

Tenuipalpid specimens were collected by shaking branches of the plant samples over a black PVC film and then transferred into an Eppendorf tube with 70% ethanol. The collected specimens were mounted on microscope slides using Hoyer's medium. The mounted slides were examined using Leica DMR microscopes with differential interference contrast (DIC). Mite identifications were conducted by M. De Giosa, A. D. Tassi and R. Ochoa at Systematic Entomology Laboratory, ARS-USDA, Beltsville, MD using available key literature and the original species descriptions (Donnadieu 1875; Canestrini and Fanzago 1876; Haller 1877; Ewing 1917; McGregor 1949; Reck 1951; Baker and Tuttle 1987; Meyer and Van Dis 1993; Khanjani and Gotoh 2008; Ueckermann and Ripka 2016; Negm et al. 2020). Plant species identification follows World Flora Online (WFO) Plant List classification (2025). Mounted slides are deposited at the Institute of Zoology, Bratislava, Slovakia (SAS) and Council for Agricultural Research and Economics - Research Centre for Plant Protection and Certification, via Lanciola 12a del Riccio, Firenze, Italy (CREA).

Detailed information on number of specimens identified, sampling locality, plant species, and month and year of the collection are provided under "Specimens examined" section. The

"Remarks" section includes comments on new host plant associations and on the literature review.

**Literature review for Slovakia**

A comprehensive literature review was conducted to identify all known records of Tenuipalpidae from Slovakia. Sources included published peer-reviewed articles, local literature, database records (see Castro *et al.* 2025), conference and symposium abstracts, and books. This review was essential for establishing a baseline prior to fieldwork and for comparing new records to existing data in neighboring countries.

**Interceptions from Bulgaria, Hungary and Netherlands**

Interceptions of tenuipalpid mites were investigated by using reports from the United States Department of Agriculture, United States Animal and Plant Health Inspection Service, and Plant Protection and Quarantine (USDA-APHIS-PPQ), covering data from 1996 onward. Archived slides of intercepted specimens originating from Bulgaria, Hungary, and the Netherlands were reviewed and re-identified by M. De Giosa, A. D. Tassi, and R. Ochoa. The reports were tabulated to include the inspection location (port of entry), country of origin, inspected host or commodity, year of interception, final genus or species determination, and the name of the acarologist responsible for the identification.

**Remarks** — *Cenopalpus pulcher* was described from Italy on hedge plant (Canestrini and Fanzago 1876). Among *Cenopalpus* species, it is the most widely distributed worldwide, with records from Argentina and Oregon (Bajwa *et al.* 2001; De Giosa *et al.* 2024). *Cenopalpus pulcher* seems to be a polyphagous species (Jeppson *et al.* 1975), feeding on more than 19 plant families (Castro *et al.* 2025). In this study, Adoxaceae and Poaceae are new host plant family records, while *C. pisifera* and *V. rhytidophyllum* are newly recorded host species. Given that this species is primarily linked to Rosaceae hosts (Castro *et al.* 2025), and no nymphs were found on conifers, we hypothesize that these collections might represent dispersion specimens rather than true hosts. This warrants further investigation, particularly through molecular analyses, to confirm whether conifers serve as feeding hosts, simply temporary shelters for dispersing mites, or if a complex of species is present. Although no morphological differences
were observed between the collected specimens and the original description, we encourage
the redescription of *C. pulcher* types. The original description is missing morphometric and
ontogenetic analyses, as well as molecular information.

**Remarks** — *Pentamerismus coronatus* was first described from Italy on Cupressaceae (Canestrini and Fanzago 1876) and has since been reported only from Greece, also on host from the same family (Hatzinikolis 1987). *Juniperus* sp. is a new host plant species record. The original description (in Italian) is too general and lacks the detail required by current taxonomic standards, providing only information on dorsal body color and a general description of setae. A redescription of the type series, including nymphs, is needed.

## Pentamerismus erythreus (Ewing)

**Specimens examined** — 9♀♀, Bojnicka Street (Prievidza), 48°46'35.7"N 18°36'14.7"E, 263 m, ex. *Thuja* sp., August 2023 (2 slides, CREA); 4♀♀, Prievidza, 48°46'50.3"N 18°37'16.8"E, 266 m, ex. *Thuja* sp., August 2023 (1 slide, SAS); 3♀♀, Karlova Ves (Bratislava), 48°9'27.4"N 17°3'2.9"E, 202 m, ex. *Thuja* sp., September 2023 (1 slide, SAS); 3♀♀, Botanical Garden of the Comenius University (Bratislava), 48°8'50.7"N 17°4'23.4"E, 152 m, ex. *Tsuga* sp.

Mill. (Pinaceae), October 2023 (1 slide, SAS); 1♀, Botanical Garden of the Comenius University (Bratislava), 48°8'50.7"N 17°4'23.4"E, 152 m, ex. *Abies nordmanniana* (Steven) Spach (Pinaceae), October 2023 (1 slide, SAS); 7♀♀, Botanicka Zahrada UK (Bratislava), 48°8'50.7"N 17°4'23.4"E, 152 m, ex. *Thuja* sp., February 2024 (1 slide, CREA).

**Remarks** — *Pentamerismus erythreus* has previously been documented in Asia and North America, primarily on plant species of the family Cupressaceae, although it was first described on Pinaceae (Castro *et al.* 2025). This study represents the first European record of the species. *Abies nordmanniana* is a new host plant species record. A comparison with the type specimens or the original description was not possible, as the type depository is unknown and the original description includes only a setal drawing. New collections from the type locality and a redescription following current taxonomic standards are needed.

## Pentamerismus juniperi (Reck)

**Specimens examined** — 1♀, Na Karlove Street (Banská Bystrica), 48°45'20.3"N 19°8'40.4"E, 377 m, ex. *Chamaecyparis* sp. (Cupressaceae), August 2023 (1 slide, SAS); 4♀ Nitra, 48°19'5.8"N 18°5'15.7"E, 167 m, ex. *Juniperus* sp., April 2024 (2 slides, CREA).
**Remarks** — *Pentamerismus juniperi* has been reported in several Asian and European countries (Castro *et al.* 2025), including the neighboring countries Hungary and Ukraine. This species is typically associated with host plants of the family Cupressaceae (Castro *et al.* 2025), though it has been reported only once on Pinaceae (Kontschán 2014). *Chamaecyparis* sp. is a new host plant genus record. The types need to be redescribed, as the original description lacks morphometric and ontogenetic information, and the drawings omit the dorso-ventral reticulation.

**Remarks** — *Pentamerismus taxi* is widely distributed across Asia, Europe and North America (Castro *et al.* 2025). *Platycladus* sp. is a new host plant species record. A new collection from the type locality is needed, as the type depository is unknown and the original description does not meet current taxonomic standards.

## Genus Tenuipalpus Donnadieu

### Tenuipalpus kobachidzei Reck

*Tenuipalpus kobachidzei* was first described from Georgia on *Clematis vitalba* L. (Ranunculaceae) and has only been reported from Ukraine on the same host. This mite species was collected on *Thymus* sp. (Lamiaceae) in Slovakia (Kalúz and Majzlan 2007). The Lamiaceae family represents a new host plant record. Similar to *P. juniperi*, *T. kobachidzei*, described by the same author in the same paper as *P. juniperi*, does not meet current taxonomic standards, including morphometric and ontogenetic details, and the drawings lack dorso-ventral reticulation.

# New records of Tenuipalpidae from Bulgaria

## Genus *Brevipalpus* Donnadieu

### *Brevipalpus lewisi* McGregor

**Specimens examined** — *Brevipalpus lewisi* was intercepted on propagative material of *Vitis vinifera* L. (Vitaceae) at San Francisco International Airport in March 2017.

**Remarks** — This mite has been reported from Africa, Asia, Europe and North America on different host plant families (Castro *et al.* 2025). *Brevipalpus lewisi* is the first genus record for Bulgaria.

# New records of Tenuipalpidae from Hungary

## Genus *Brevipalpus*

### *Brevipalpus essigi* Baker

**Specimens examined** — *Brevipalpus essigi* was intercepted on cuttings of *Sorbus pseudolatifolia* K.P. Popov (Rosaceae) at John F. Kennedy International Airport in August 1996.

**Remarks** — *Brevipalpus essigi* was previously reported in Europe only from Greece (Hatzinikolis 1968). *Sorbus pseudolatifolia* is a new host family and species association for this mite.

## Genus *Tenuipalpus*

### *Tenuipalpus sarcophilus*

**Specimens examined** — *Tenuipalpus sarcophilus* Welbourn and Beard was intercepted on *Conophytum* sp. (Aizoaceae), *Haworthia* sp. (Asphodelaceae), *Lenophyllum* sp. (Crussulaceae), *Stapelia* sp. (Apocynaceae) at San Francisco International Airport in July 2022.

**Remarks** — This represents the second European record for this species, which it has been previously reported in Italy (De Giosa *et al.* 2021). The plant genera *Conophytum*, *Haworthia*, *Lenophyllum*, *Stapelia* and families Aizoaceae and Asphodelaceae are new host associations for *T. sarcophilus*. Despite *T. sarcophilus* preference for feeding on succulents, these new host plant family associations may be incidental. Succulent plants and related genera are often cultivated together (Eggli 2002), potentially leading to accidental infestations. The cultivation practices and management of certain ornamentals demand careful attention, as they may inadvertently aid in the dispersion of this mite (Hoy 2011).

# New records from the Netherlands

## Genus *Brevipalpus*

### *Brevipalpus obovatus* Donnadieu

**Specimens examined** — *Brevipalpus obovatus* was intercepted on *Hibiscus* sp. plant (Malvaceae) at Seattle-Tacoma International Airport in May 2006.

**Remarks** — *Brevipalpus obovatus* is widely distributed Africa, Asia, Europe and the Americas and feeds on a broad range of host plant families. In Europe, it has previously been reported from eight countries (Castro *et al.* 2025). This species is vector of solanum violifolium ringspot virus and cestrum ringspot virus (de Lillo *et al.* 2021)
**Genus Pentamerismus**

**Pentamerismus erythreus**

**Specimens examined** — *Pentamerismus erythreus* was intercepted on cuttings of *C. lawsoniana* at John F. Kennedy International Airport in February 2001.

**Remarks** — *Pentamerismus erythreus* is the first *Pentamerismus* species reported from the country. However, further confirmation of its presence through surveys is needed. The Netherlands is the largest exporter of agricultural commodities in Europe (Government of the Netherlands, 2025). Consequently, uncertainty remains regarding whether *C. lawsoniana* is naturally occurring in the Netherlands or if it arrived as an agricultural commodity from another country, passing through Dutch ports en route to other destinations (Qiang *et al.* 2020).

**Discussion**

This study presents the first comprehensive faunistic survey of tenuipalpid mites in Slovakia and expands recent findings from Ukraine, with additional records from Bulgaria, Hungary, and the Netherlands based on interception data. Through extensive field sampling and meticulous morphological identifications, we uncovered 13 species across three genera *Cenopalpus*, *Pentamerismus*, and *Tenuipalpus*. The majority of species were associated with coniferous hosts, particularly within Cupressaceae and Pinaceae, which are widespread in urban and ornamental landscapes. Notably, several *Pentamerismus* species, including *P. arbutusae*, *P. canadensis*, *P. collinus*, and *P. erythreus* were recorded for the first time in Europe. These detections extend their known distributions from North America, Africa, or Asia and emphasize the value of targeted faunistic surveys in revealing overlooked or recently introduced species (McGregor 1949; Knowlton and Ma 1950; Pritchard and Baker 1952; Pritchard and Baker 1958; Baker and Tuttle 1964; Prasad 1970; Thewke and Enns 1970; Baker and Tuttle 1972; Lehman 1982; Hennessey *et al.* 1986; Baker and Tuttle 1987; Evans *et al.* 1993; Meyer and Van Dis 1993; Khosrowshahi and Arbabi 1997; Sağlam and Çobanoğlu 2010). Our findings also include numerous new host plant associations, suggesting broader ecological adaptability than previously documented for some taxa. The faunistic survey in Slovakia revealed twelve species currently known from the country, many of which had not been previously recorded in Central Europe. In Ukraine, complementary sampling conducted in botanical gardens led to the discovery of new national records and host associations, including multiple *Pentamerismus* species previously unreported from the country (Zhovnerchuk *et al.* 2021). These findings confirm the presence and establishment of several species with potential economic relevance, especially in ornamental landscapes and nursery plant systems.

Beyond regional biodiversity documentation, our results have important biosecurity implications. Several of the recorded species, such as *P. erythreus* and *T. sarcophilus*, are known to cause damage to ornamental plants through leaf discoloration and necrosis, compromising their aesthetic value (Lehman 1982; Welbourn *et al.* 2017). These symptoms are particularly problematic for aesthetic plant quality and may result in commercial losses. The Netherlands, a major exporter of ornamental plants (Dutch Horticulture 2025), has been implicated in the unintentional distribution of *T. sarcophilus*, highlighting the need for routine surveillance in production and export facilities. In addition to detecting new records, this study underscores the importance of re-evaluating historical identifications. The *Brevipalpus phoenicis* species complex, for example, includes multiple cryptic species with distinct biological traits, including virus transmission capabilities (de Lillo *et al.* 2021; Ramos-Gonzalez *et al.* 2023). Older regional records, including those from Hungary (Kerényiné Nemestóthy and Vályi 1978) and Ukraine (Chumak 2003), may have misidentified *B. phoenicis*, potentially overlooking important risks associated with virus transmission. The slide depository of the Ukrainian collection reported by Livschitz and Mitrofanov remains unknown, despite efforts by the first author to locate it. This highlights the need for new faunistic surveys to ensure accurate pest risk assessments.
In summary, our work illustrates the essential role of faunistic surveys and interception analysis in detecting new mite introductions, updating species distributions, and identifying previously unknown host associations. Accurate species identification, particularly of economically relevant taxa, is foundational to effective quarantine, pest management, and conservation strategies across Europe.
