Bat ectoparasites: chigger mites (Trombiculidae), ticks (Ixodidae and Argasidae), and bugs (Cimicidae) in the Eastern Palaearctic.

Nine species-level taxa of bat ectoparasites, three chigger mites (Trombiculidae), three hard (Ixodidae), and one soft tick (Argasidae) species, as well as two bug (Cimicidae) species from nine bat species hosts were detected in the Eastern Palaearctic. Trombiculid larvae of Leptotrombidium schlugerae, Leptotrombidium album, and Ascoschoengastia latyshevi were first recorded on bats in the temperate zone of eastern Russia. L. schlugerae was more abundant than A. latyshevi in the same study sites in Eastern Siberia, and the main hosts of both chigger species were Plecotus ognevi and Eptesicus nilssonii. Ixodid ticks Dermacentor marginatus, Ixodes simplex, and Ixodes sp. were sampled from bats in Kazakhstan, the Far East, and Eastern Siberia, respectively. Phylogenetic analysis based on Cox1, 16S rDNA, and ITS2 sequences of I. simplex showed that the specimens from the Far East grouped into a clade distributed in the Eastern Palaearctic and India. In turn, the specimen of Ixodes sp. from Eastern Siberia was most closely related to Ixodes soricis and Ixodes angustus with p-distance of 9.8-10.7% (Cox1), suggesting that this tick probably belongs to a new species. Argas vespertilionis larvae were collected from three widespread bat species in Kazakhstan. Two bug species, Cimex pipistrelli and Cimex aff. lectularius, were recorded in the Far East and Eastern Siberia, respectively. Specimens from Transbaikalia were morphologically identified as Cimex lectularius. However, they differed from the latter by 12.5-12.9% of Cox1 sequences, indicating that C. aff. lectularius may be a new species.

Two New Species and New Records of Mites of the Genus Parichoronyssus (Acari: Macronyssidae) From South American Bats (Chiroptera), With a Key to the Known Species of the Genus.

Derived from exhaustive search of mites of the genus Parichoronyssus associated with South American Bats, we found two new species associated with Phyllostomid, Emballonurid, and Noctiniolid bats: Parichoronyssus alexanderfaini n. sp. associated with Rhinophylla pumilio Peters; Parichoronyssus gettingeri n. sp. associated with Rhynchonycteris naso Wied-Newied, and Noctilio leporinus Linneo. Herein we give the description of those new species, and additionally is included several new records for Parichoronyssus from the region, as well as providing a key to the 11 species of Parichoronyssus.

Ectoparasites and Pathogens of Kuhl's Pipistrelle Pipistrellus kuhlii (Kuhl, 1817) (Chiroptera: Vespertilionidae): Our Own and Published Data Review.

Here we report the results of our own survey and literary published data on the ectoparasite fauna and pathogens of the alien bat species, the Kuhl's pipistrelle Pipistrellus kuhlii (Kuhl, 1817) (Chiroptera: Vespertilionidae). This bat is a host of 36 species of parasitic mites, ticks and insects (including accidental findings) and 13 species of pathogens (protozoa, bacteria, viruses). The flea Ischnopsyllus variabilis is re-corded on this host for the first time. We have found that outside of the host ancestral range, the core of the bat parasite fauna is significantly different due to the loss of host species-specific ectoparasites. Particularly, in Russia, only 6 species of parasitic arthropods have been recorded for Kuhl's pipistrelle and all of them are host genus-specific. At the same time, the features of ecology and occasional finds of extrinsic parasites allow to suggest that P. kuhlii has wide contacts with animals which are the reservoirs of zoonotic infec-tions, that in combination with the fact of isolation of several pathogens from this species (including two coronaviruses) points to a possible medical importance of Kuhl's pipistrelle.

New record, host and localities of bat mite of genus Chirnyssoides (Acari, Sarcoptiformes, Sarcoptidae) / Novo registro, hospedeiros e localidades do ácaro de morcego do gênero Chirnyssoides (Acari, Sarcoptiformes, Sarcoptidae)

Chirnyssoides parasitizes the anterior and posterior edges of bat wing membranes. Possibly due to a lack of studies, its distribution is believed to be restricted to a few countries of Central and South America, but its actual range is probably wider. The purpose of this paper is to report the presence of Chirnyssoides amazonae on the bat Carollia perspicillata in the state of Rio de Janeiro, Brazil, and to present a checklist of hosts and localities for Chirnyssoides. Eleven females and 22 egg clusters of C. amazonae were collected from 11 individuals of C. perspicillata captured in Tinguá Biological Reserve using mist nets. Our search of the literature came up with 69 records of Chirnyssoides. There are reports of Chirnyssoides caparti, Chirnyssoides amazonae, Chirnyssoides brasiliensis and Chirnyssoides phyllostomus in Brazil. This paper reports the first record of Chirnyssoides amazonae in the state of Rio de Janeiro and the second in Brazil, indicating that their known distribution extends to the south. There are records of C. amazonae and C. surinamensis parasitizing C. perspicillata, but this is the first record of C. amazonae on C. perspicillata in Brazil.

Chirnyssoides está associado às bordas anteriores e posteriores das membranas das asas de morcegos. Sua distribuição é restrita a alguns países da América Central e do Sul, principalmente devido a falta de estudos. O objetivo deste trabalho foi registrar Chirnyssoides amazonae em Carollia perspicillata no Estado do Rio de Janeiro, bem como apresentar uma lista de hospedeiros e localidades para Chirnyssoides. Onze fêmeas e 22 aglomerados de ovos de C. amazonae foram colhidos em 11 indivíduos de C. perspicillata capturados na Reserva Biológica do Tinguá, utilizando redes de neblina. Na literatura encontramos 69 registros de Chirnyssoides. Para o Brasil há relatos de Chirnyssoides caparti, Chirnyssoides amazonae, Chirnyssoides brasiliensis e Chirnyssoides phyllostomus. Este estudo relata o primeiro registro de Chirnyssoides amazonae no Rio de Janeiro e o segundo para o Brasil expandindo sua distribuição para o sul. Em C. perspicillata há registros de C. amazonae e C. surinamensis, sendo o primeiro registro de C. amazonae em C. perspicillata no Brasil.
