Hard ticks (Acari: Ixodidae) are the economically and ecologically most important blood-sucking arthropod vectors that can transmit disease agents under temperate climate. In this group, the highest number of species (currently nearing 270) belongs to the genus Ixodes. For this review, more than 400 papers related to this genus in the context of Russia were checked for data on the host records, locations of collection, as well as ecology of assigned tick species. This monograph compensates for the lack of a similarly comprehensive English-language overview of Ixodes species in the region of Russia for nearly half century, and also makes a large set of data easily available for international readers, which is especially important if the original source is difficult to access from outside this country. In addition, the data from a significant number of papers on this topic available only in the Russian language are made accessible through this work. [ABSTRACT FROM AUTHOR]

The reaction paper provides a brief response and critique Khan et al.'s (2023) proposal categorisation about dividing four subgenera of the genus Raphignathus Dugès. The present work contains following nomenclatural recommendation in Raphignathus: (1) Raphignathus bengalensisModak, 1991 and R. sayedi Gomaa and Hassan, 1986 are considered here as nomina nuda due to no formally publishing. (2) Raphignathus curtipilus Berlese, 1888 is transferred to the genus Eustigmaeus Berlese. (3) Raphignathus striatus Trägardh, 1904 is moved to the genus Prostigmaeus?

Simple Summary: This study provides detailed information on six previously described species of syringophilines associated with starlings and records new host and locality data. Additionally, three new species are described: Aulonastus indonesianus sp. n., Aulonastus anais sp. n., and Syringophiloidus poeopterus sp. n., from various starling hosts across Indonesia, Papua New Guinea, and Tanzania. The study reveals that species from the genera Syringophiloidus and Syringophilopsis exhibit a broad host range among passerine birds, suggesting a long-established symbiotic relationship before the global dispersal of starlings. In Europe, the Eurasian Starling hosts Krantziaulonastus, while in Africa, related niches are occupied by Picobiinae mites. The research highlights the intricate coevolutionary dynamics between quill mites and their avian hosts. Quill mites of the family Syringophilidae are widely distributed parasites of birds inhabiting the interior of feather quills. In this paper, we provide detailed information on the host spectrum and distribution for six previously described species of syringophilines associated with starlings with new host and locality records. Additionally, we describe three new species: Aulonastus indonesianus Marcisova, Skoracki, and Patan sp. n. from the Common Hill Myna Gracula religiosa Linnaeus in Indonesia (Java) and the White-necked Myna Streptocitta albicollis (Vieillot) in Indonesia (Celebes); Aulonastus anais Skoracki and Patan sp. n. from the Golden Myna Mino anais (Lesson) in Papua New Guinea; and Syringophiloidus poeopterus Skoracki and Patan sp. n. from the Abbott's Starling Poeoptera femoralis (Richmond) in Tanzania. Finally, we explore the host–parasite interactions within the system comprising starlings and syringophiline mites. [ABSTRACT FROM AUTHOR]

This paper describes two new species of the genus Ologamasus (Acari: Ologamasidae), namely Ologamasus margaridae n. sp. and Ologamasus tuberculatus n. sp., based on females, males and nymphal stages collected in apple orchards (Malus domestica Borkh.) in southern Brazil. Ologamasus tuberculatus has a distinctive pair of large pores inserted on protuberances on the dorsal shield.

Two new eriophyid mite species (Acari: Prostigmata: Eriophyoidea) were described from the host plants of the genus Callerya Endl. during a field survey in China: Tetra nitidae sp. nov. vagrant on leaves ofCallerya nitida (Bentham) R. Geesink (Leguminosae),and Calepitrimerus calleryus sp. nov. vagrant on leaves ofCallerya tsui (F. P. Metcalf) Z. Wei & Pedley. Both species caused no apparent symptoms in their host plants. Additionally, this paper provides a supplementary morphological description and illustrations of Fujianacarus wisterianis Song, Xue & Hong, 2008 (Eriophyoidea).

The genus Cryptofavognathus is represented with only two species: Cryptofavognathus anatolicus Doğan & Dönel and C. afyonensis (Koç & Akyol). The third species, Cryptofavognathus bellussp. nov., was detected during a faunistic study on raphignathoid mites of Sansa Gorge (Türkiye) and described here. This paper also presents a current species list for the family Cryptognathidae Oudemans, with the following taxonomic recommendation in the genus Favognathus Luxton: Favognathus aegyptiaca (Fawzy, Khalil & Yassin) and Favognathus rosetta (Fawzy, Khalil & Yassin) described from Egypt should be considered species inquirendae due to their inadequate diagnostic characteristics and poor descriptions.

Background: Soil-dwelling organisms populate the spaces--referred to as interstices--between the litter on the soil surface and the pores in the soil's organo-mineral matrix. These organisms have pivotal roles in soil ecosystem functions, such as the breakdown and decomposition of organic matter, the dispersal of bacterial and fungal spores and biological habitat transformation. These functions, in turn, contribute to broader ecosystem services like carbon and nutrient cycling, soil organic matter regulation and both chemical and physical soil fertility. This study provides morphological data pertaining to a range of soil organism sizes, specifically in Argiudol soils subjected to varying levels of agricultural activity in the Rolling Pampas Region, one of the world's most extensive and fertile plains. The primary focus is on soil microarthropods--namely, Acari (mites) and Collembola (springtails)--with a body width of less than 2 mm. These organisms constitute the majority of life in the intricate soil pore network. Additionally, the study documents species of earthworms (Oligochaeta, Crassiclitelata), recognised as ecosystem engineers for their ability to create physical channels in the soil matrix and to distribute organic matter. Moreover, the study includes measurements of morphological traits of soil-dwelling "macrofauna" (organisms with a body width greater than 2 mm), which are also implicated in various soil ecosystem functions. These include population regulation by apex predators, organic matter decomposition, biogenic structure formation, nutrient mobilisation and herbivory. New information:In this paper, we report both the geographical locations and individual measurements of key morphological traits for over 7,000 specimens, covering a range of soil-dwelling organisms. These include springtails (Entognatha, Collembola), mites (Arachnida, Acari), earthworms (Oligochaeta, Crassiclitellata) and additional soil macrofauna. All specimens were collected from typical Argiudol soils located in three distinct agricultural systems characterised by varying levels of land-use intensity. To our knowledge, no other dataset exists providing this information for the Argentinian Pampas. [ABSTRACT FROM AUTHOR]

The iolinid mite Coccalicus clavatus Willmann, 1952 was collected during a survey from the soil of Gilanegharb, Kermanshah, Iran in 2022. This species was first described in the family Alycidae by Willmann in 1952 and then André and Uusitalo transferred it to the family Iolinidae in 2006, accompanied by transferring species from the genus Paratydaeolus to the genus Coccalicus. Some challenges about species characters of this mite are discussed in this paper and the synonymy of C. lukoschusi and C. clavatus is proposed. The genus consists of 12 species with clavate trichobothria, and is related to various habitats like soil, stored products, under barks, on leaves of different plants, and on birds. They have been reported from Europe, Antarctica and North America and this is the first record of the Coccalicus mites from Asia. [ABSTRACT FROM AUTHOR]

This paper reports the results of our studies of the morphological ontogeny of Neoseiulus cucumeris (Oudemans) based primarily on specimens reared in a laboratory at Manaaki Whenua Landcare Research, Auckland, New Zealand. We describe all postembryonic stages and illustrate them in detail: the larva, protonymph, deutonymph (male and female), and adult female and male.

As a group of ectoparasites, chiggers (larvae of chigger mites) are the exclusive vector of scrub typhus (tsutsugamushi disease). Rodents are the most important hosts of chiggers. The Anderson's niviventer rat, Niviventer andersoni, is an endemic species of rodent in China. However, few studies have involved this endemic rodent species and its ectoparasites including chiggers. According to the field investigation in five provincial regions of southwest China between 2001 and 2019, this paper retrospectively analysed the infestation and distribution of chiggers on the body surface of N. andersoni in southwest China for the first time. From 77 Anderson's niviventer rats captured, a total of 527 chiggers were collected and they were identified as 39 species and nine genera in two subfamilies of family Trombiculidae. Of 39 chigger species identified, Leptotrombidium deliense and L. scutellare are the most important vectors of scrub typhus in China. The overall infestation indexes were PM = 29.87%, MA = 6.84 and MI = 22.91, and the indexes of chigger mite community were Mf = 39, H' = 2.60, E = 0.71 and D = 0.12. The dominant chigger species are L. wenense, L. xiaguanense and L. fujianense with a total Cr = 51.04%, among which L. wenense is one of the six main vectors of scrub typhus in China. The dominant chigger species are of aggregated distribution among different individuals of the rats. [ABSTRACT FROM AUTHOR]

[Display omitted] • The geographic distribution of Rhipicephalus linnaei is much wider than previously known. • Rhipicephalus linnaei was recorded on a dingo. • The record of R. linnaei on a dingo suggest that dingoes might aid the spread of Ehrlichia canis in Australia. • We discuss possible incursion routes and how E. canis has apparently spread rapidly in Australia. The tropical brown dog tick, Rhipicephalus linnaei , is a tick of much medical, veterinary, and zoonotic importance. This tick has a nearly world-wide distribution due to its ability to survive and propagate in kennels and houses. Rhipicephalus linnaei is the vector of Ehrlichia canis , the causative agent of canine monocytic ehrlichiosis, an often debilitating disease of canids and, occasionally, humans. To prevent incursion of E. canis into Australia, dogs entering Australia have been required to have a negative immunofluorescence antibody test for E. canis. In May 2020 however, E. canis was detected in Western Australia. The detection of E. canis in Australia prompted disease investigation and concerted surveillance for R. linnaei and E. canis in regions across Australia. These investigations revealed that R. linnaei was established far beyond the previously recognised geographic range limits of this tick. In the present paper, using records from various collections, published data, and data from our network of veterinarian collaborators and colleagues, we update the current geographic range of R. linnaei in Australia. Our analyses revealed that the geographic range of R. linnaei in Australia is much wider than was previously supposed, particularly in Western Australia, and in South Australia. We also map, for the first time, where E. canis has been detected in Australia. Last, we discuss the possible routes of incursion and subsequently the factors which may have aided the spread of E. canis in Australia which led to the establishment of this pathogen in Australia.

The study of Acari associated with cricetid rodents in Mexico began at the end of the 1930s. Despite efforts to gathering the information, only listings were built, but none of these studies present an analysis of the available data. A search was made through electronic databases; in addition, some not published records contained at Collection of Laboratorio de Acarología, Facultad de Ciencias, Universidad Nacional Autónoma de México were included in the inventory. Combining the literature records and those deposited in the collection, the total number of species of Acari associated with this family of rodents is 165, distributed in two superorders, four orders, 15 families, and 57 genera. Of the 15 families registered, the richest is Trombiculidae (70 nominal species and 75 taxa), followed by Laelapidae (39 and 42, respectively), Ixodidae (13 nominal and 16 taxa), and Leewenhoekiidae (13 nominal and taxa). From the bibliographic searches, a total of 76 papers were recovered with information on the association between Acari and cricetid rodents in Mexico. The main detected approach in the literature was taxonomic (75 works) and one on detection of pathogens. From the 145 known species of cricetids recorded in Mexico, only 72 (distributed in 18 genera) have been studied and found to host Acari. The use of regionalization of Mexico in provinces allowed us to map the records of Acari associated to cricetids in the most natural approximation of their distribution. We recognize and discuss seven factors that favor the scarcity and asymmetry of acarological studies in Mexico., (© The Author(s) 2022.

Simple Summary: We report on the occurrence of parasitic quill mites of the family Syringophilidae on the well-known avian group birds-of-paradise. Our investigation resulted in the discovery of two new species of mites belonging to the subfamily Picobiinae, which has never before been recorded on birds-of-paradise. We hypothesise that the interspecific sexual behaviour of paradisaeids, which involves copulation with non-closely related host species, may have facilitated the spread of syringophilid mites between different and unrelated host species. These findings highlight the potential role of sexual behaviour in the distribution and transmission of parasitic quill mites among avian hosts. While birds-of-paradise (Passeriformes: Paradisaeidae) are a well-known group of birds, our understanding of their parasites is still limited. This study reports on parasitic quill mites of the subfamily Picobiinae (Acariformes: Syringophilidae), which have never before been recorded on this group of birds. The mite specimens presented in this paper were collected from birds-of-paradise that had been captured in Papua New Guinea and Indonesia in the years 1910–1911 and are now deposited in the Bavarian State Collection of Zoology, Munich, Germany. Two syringophilid species are described as new to science: (i) Picobia frankei sp. n. from the magnificent riflebird Lophorina magnifica, the glossy-mantled manucode Manucodia ater, and the crinkle-collared manucode Manucodia chalybatus, and (ii) Gunabopicobia garylarsoni sp. n. from the twelve-wired bird-of-paradise Seleucidis melanoleucus and the lesser bird-of-paradise Paradisaea minor. We hypothesise that the presence of both picobiine species on phylogenetically unrelated paradisaeids may be caused by the sexual behaviour of these birds, where interspecific copulations may play a role in the switching of parasites between non-closely related host species.

Teneriffiidae (Prostigmata: Anystoidea) is a poorly studied family of predatory mites that are recognized among its superfamily by thick raptorial palps, weakly marked naso, and rosette-like bothridial organs on prodorsum. In the present paper, a new species – Teneriffia aethiopica sp. nov. – is described from the soil material collected in Ethiopia. It is a relatively large species (about 1 mm); almost all coxal fields (I–III) have at least five epimeral setae; prodorsal shield and palpal oncophysis are present; ventral opisthosoma does not exhibit neotrichy, i.e. there are only six to seven pairs of aggenital setae ag present; pseudanal setal series is represented by four pairs of setae ps; claws on tarsi I–II are strongly bipectinate without empodia, and claws on tarsi III–IV are slightly serrate with smooth, hook-like empodia (almost the half of the size of each claw). Although representing unique characters, the rest of its morphological features suggest that it may form a group with members of the two currently defined genera Heteroteneriffia Hirst, 1925 and Teneriffia Thor, 1911 of which further study and re-examination have recently been proposed; hence, the present paper contributes some new knowledge that may be helpful in a future revision of this intriguing family.

Ten Opilioacaridae species from the genera Caribeacarus and Neocarus are found in subterranean habitats in Brazil, and several new species are waiting to be described. As part of our studies on cave opilioacarid species, two new species from Peruaçu Caves National Park, Minas Gerais state, are described in the present paper. The two new species present six or more d type setae on the palp, with a stout and rounded lobe: Neocarus chimerasp.nov. with 6 to 9 setae and Neocarus peruassusp.nov. presents 6 or 7 foliate setae (d1). The combination of these characters is a transitional state observed between Neocarus (4 to 9 foliate d type setae on palp, with a stout and rounded lobe) and Caribeacarus (8 to 12 foliate d type setae on palp, with a fine and pointed lobe). The systematic position of the new species is briefly discussed. Additionally, the habitat description and some ecological notes are provided for both new species. [ABSTRACT FROM AUTHOR]

Simple Summary: In addition to causing dermatitis, some gamasid mites are also the vector or potential vector of some zoonotic diseases. Located in the northwest Yunnan Province of southwest China, the Three Parallel Rivers Area of China is one of the hotspots of biodiversity research in the world. Based on the previous field survey in the Three Parallel Rivers Area from 2001 to 2015, this paper reports the species diversity and basic community characteristics of gamasid mites on small mammals in this unique geographical area for the first time. From the body surface of 3830 small mammal hosts, 26,048 gamasid mites were collected and identified as 10 families, 21 genera and 82 species (excluding 847 unidentified specimens) with high species diversity. The species diversity of the gamasid mite community fluctuated greatly in different elevation gradients. The highest peaks of species richness and β diversity appeared at altitudes of 3000–3500 m (S = 42) and 1500–2000 m (β = 17.5), respectively. The species abundance distribution of the mites was successfully fitted by Preston's lognormal model, and the total number of gamasid mite species in the Three Parallel Rivers Area was estimated to be 153 species. (1) Background: Gamasid mites are a large group of arthropods, and some of them are of medical importance. Besides directly biting humans and causing dermatitis, some gamasid mites are the vector of rickettsialpox and potential vector of hemorrhagic fever with renal syndrome (HFRS). The Three Parallel Rivers Area of China is one of the hotspots of biodiversity research in the world, with complicated topographic landforms, different types of vegetation, special elevation gradients and high biodiversity. (2) Methods: Species richness (S): the Shannon–Wiener diversity index (H), Simpson dominance index (D) and Pielou evenness index (E) were used to analyze the basic community structure. The β diversity (Cody index) was used to reflect the diversity difference between any two adjacent elevation gradients. The method based on Preston's lognormal model for species abundance distribution was used to estimate the total number of gamasid mite species. (3) Results: A total of 3830 small mammal hosts captured from the nine survey sites were identified as 44 species, 27 genera and nine families in five orders. Apodemus chevrieri, Eothenomys miletus and A. draco were the dominant host species with a total constituent ratio Cr = 52.037%. From the body surface of the hosts, 26,048 gamasid mites were collected and identified as 10 families, 21 genera and 82 species (excluding 847 unidentified specimens) with high species richness (S = 82) and diversity (H = 2.33). The three dominant mite species were Dipolaelaps anourosorecis, Laelaps nuttalli and L. echidninus, with a total Cr = 64.46% (16,791/26,048). There are significant differences in the species composition, species diversity and dominant species of gamasid mites on different hosts. The species diversity of the mite community fluctuated greatly in different elevation gradients. The highest peaks of species richness and β diversity appeared at altitudes of 3000–3500 m (S = 42) and 1500–2000 m (β = 17.5), respectively. The species abundance distribution of the mites was successfully fitted by Preston's lognormal model with S ^ (R) = 19 e − [ 0.22 (R − 0) ] 2 (α = 0.22, R2 = 0.9879). Based on fitting the theoretical curve by Preston's model, the total number of gamasid mite species was estimated to be 153 species. (4) Conclusions: Gamasid mites on small mammals are abundant with complex community structures and high species diversity in the Three Parallel Rivers Area of China. There is an apparent community heterogeneity of the mites on different hosts and in different environments. [ABSTRACT FROM AUTHOR]

Simple Summary: Natural enemies of cheatgrass, an invasive plant in the western USA that is associated with recent increases in destructive wildfires, were sought as part of a classical biological control program targeting that plant. A population of mites was discovered infesting cheatgrass plants in central Bulgaria and determined to be a new species using morphological, morphometric analysis (i.e., measurement of specific body parts) and DNA barcoding (i.e., comparison of DNA sequences in genes shared by all mite species). Without these modern analytical tools, this mite would probably have been considered as the same species as another mite that infests other plants. This new mite species will now be tested to determine if it is suitable for importation and release in the USA as a biological control agent of cheatgrass. A new species of eriophyoid mite, Aculodes marcellisp. nov., was discovered on cheatgrass, Anisantha tectorum (L.) Nevski (syn. Bromus tectorum L.), an annual grass that is native to Eurasia and Northern Africa. This grass was introduced to North America near the end of the 19th century and now is widespread and associated with the observed increases in the size, frequency, and intensity of wildfires in western N. America. In this paper, A. marcellisp. nov., is morphologically described and illustrated. Compared with other Aculodes spp., it differs based on morphology and the sequence of the mitochondrial cytochrome oxidase gene, subunit I (MT-CO1). Results of morphometric analysis showed clear differentiation between A. marcellisp. nov., and the most similar congener, A. altamurgiensis from Taeniatherum caput-medusae. Analysis of MT-CO1 sequence divergence revealed significant levels of genetic variation (17.7%) and supported the results from the morphometric analysis; therefore, it is determined that they are two different species. Aculodes marcellisp. nov., is a new candidate agent for classical biological control of A. tectorum. [ABSTRACT FROM AUTHOR]

The paper deals with three species, of which one is new to science, Torrenticola (Megapalpis) yii Gu & Guo sp. nov., and two are newly recorded species for the Chinese fanua, Torrenticola (Torrenticola) neoungeri Pešić, Asadi & Smit, 2019 and Neoatractides (Allotorrenticola) malayensis (Wiles, 1991). Torrenticola (Megapalpis) yii Gu & Guo sp. nov. is the second species of Megapalpis in China, and the 21st in the world. Meanwhile, Neoatractides (Allotorrenticola) malayensis (Wiles, 1991) represents a newly recorded subgenus Allotorrenticola from China. [ABSTRACT FROM AUTHOR]

Sennertia is a diverse and widely distributed genus of mites within the family Chaetodactylidae, and the most successful group of mites in establishing phoretic relationships with bees. Although 77 valid species of Sennertia are known in the world, only two species, Sennertia (Sennertia) gargantua Zachvatkin and Sennertia (S.) zhelochovtsevi Zachvatkin have been recorded from Turkey. But, these two bee-associated species have not been noticed and not listed in the studies on mite fauna of Turkey. OConnor & Klimov in 2003 and Klimov & OConnor in 2008 stated that the distribution information of Sennertia (S.) gargantua in Turkey was probably an error. This paper reports the presence of Sennertia (S.) gargantua on a Carpenter bee in Turkey with an additional new record of the genus from Turkey, viz. Sennertia (S.) cerambycina (Scopoli). In the present work, a key to the known species for Turkey is also provided. It is noticed that genital setae are duplicated on the right side of an examined specimen of Sennertia (S.) gargantua. In the genus, some variations and local anomalies have been previously recorded; however, no abnormalities of the genital setae in Sennertia have been reported. [ABSTRACT FROM AUTHOR]

Gamasiphis Berlese is the most diverse genus of Ologamasidae, with 74 described species, seven of which were described from Ecuador.

Complementary descriptions of two previously described species, also collected in this study, are presented.

This paper is a review of the mite family Parholaspididae, including 163 species and 14 genera. We provide a diagnosis for the family and each genus, and a key to the genera. For each species we provide a synonymy and bibliography, information about the type locality, habitat, and institutional deposition of type specimens.

Acari represent the most diverse group within the arachnids with some 60,000 described species. It is generally believed that most species of mites are waiting to be discovered and described. Zootaxa was the most important journal for mite taxonomy during the last twenty years (2001 to 2020). It published 1305 papers by 1057 authors during these two decades, with descriptions of 3271 new taxa/names, which account for 24.4% of the total indexed in Zoological Record. The numbers of new synonyms of Acari in Zootaxa (334) also accounted for nearly a quarter (24.9%) of the total published during this period. These data indicate that Zootaxa has been an important and leading journal for acarologists to document the diversity of mites and ticks in the world.

This paper reports on three species of mites of the genus Gaeolaelaps from Altai Mountains, Russia. Gaeolaelaps altaiensis sp. nov., G. lenis Vatankhah Nemati were collected from nests of Lasius sp. and Formica sp. (Hymenoptera: Formicidae), respectively, and G. euparadactylifer sp. nov. from moss on the shore of the Teletskoye Lake. The new species have the unusual character state of short peritremes, ending near the middle of coxae II. In G. euparadactylifer sp. nov., the pretarsal paradactyli on legs II-IV are strongly elongated, apically pointed and with their tips projecting well beyond the claws. Both new species are described based on morphological characters of the adults. In addition, the male of Gaeolaelaps lenis is described for the first time.

A checklist of the Acari type specimens deposited in the Jalal Afshar Zoological Museum (JAZM), Department of Plant Protection, Faculty of Agriculture, University of Tehran, Karaj, Iran is given. From a total of 451 type specimens (which comprises 166 valid species names) cited in the list, 164 are available and two are lost. Based on the comparison of these type specimens, the following taxonomic change is proposed in this paper: Erythraeus (Zaracarus) ueckermanni is considered as a valid species and is not a junior synonym of Erythraeus (Zaracarus) budapestensis.

Studies on obligatory, ectoparasitic mites of the family Syringophilidae associated with birds in Germany were scarce and scattered over the time. This paper summarizes current knowledge of German syringophilid fauna. We present new host and locality records and describe two new species: Niglarobia lapponicasp. nov. and Charadriineopicobia ristowisp. nov. from the quill feathers of bar-tailed godwit Limosa lapponica (Linnaeus) (Scolopacidae).

In this paper, we studied the morphological ontogeny of Neoseiulus barkeri Hughes (Acari: Phytoseiidae) based on specimens collected from Southwest University (Chongqing, China) and reared in laboratory of Shanxi Agriculture University.

Bdella longicornis (Linnaeus, 1758) is a widespread species. There has been no description of its immature stages before. In this paper, we redescribe its female adult and describe its four immature stages for the first time based on the specimens from P. R. China. Meanwhile, the ontogeny of chaetotaxy in B. longicornis is discussed.

Besides being an important pest in agriculture and forestry, the Himalayan field rat (Rattus nitidus) can be the reservoir host of many zoonoses. Some ectoparasitic gamasid mites on rodents (rats, mice and voles, etc.) are associated with some zoonoses. A field investigation was made in 39 counties in Yunnan Province of southwestern China between 1990 and 2015, and a total of 928 R. nitidus were collected. Based on some strategies of "data mining", the present paper analyzed the infestation and distribution of gamasid mites on the body surface of R. nitidus in Yunnan for the first time. There were 19,585 individuals of gamasid mites collected, and 18.971 of them were identified as 54 species and 19 genera under seven families. The results indicated that R. nitidus has a high potential to harbor abundant gamasid mites of diverse species. The two dominant mite species, Laelaps nuttalli and Laelaps echidninus, had an aggregated distribution among different individuals of R. nitidus. The identified 54 species of gamasid mites showed a high species diversity on a single rat species (R. nitidus), and the diversity index at the family level was higher than that at the genus level. The infestation of R. nitidus with gamasid mites in the different habitats and altitude gradients was uneven and heterogenic, which reflects the infestation bias in different environments. Most gamasid mites tended to infest male and adult rats rather than female and juvenile ones, which reflects the infestation bias on different sexes and ages. Based on Chao1's formula, the total number of gamasid mite species on R. nitidus was estimated to be 66. [ABSTRACT FROM AUTHOR]
