    We present the first record of Macronyssus heteromorphus Dusbábek et Radovsky, 1972 (Mesostigmata: Gamasina: Macronyssidae) in the Trans-Urals. Our record is located 1,500 km northwest from the nearest site of this species’ previous record. The collected specimen (male) was found parasitizing a female of Myotis brandtii (Eversmann, 1845) (Chiroptera: Vespertilionidae). The records of both Macronyssus heteromorphus and its host species are the first ones in the Khanty-Mansi Autonomous Area. In this article, we present the measurements of this species for the first time, including the measurements that were omitted from the first description of this mite. Our finding also points to the existence of an area where Myotis brandtii and Myotis sibiricus Kastschenko, 1905 are sympatric

    A review of mites and ticks parasitizing rock lizards (Lacertidae: Darevskia)

    Rock lizards of the genus Darevskia are interesting research models due to their asexual reproduction. Ectoparasitic mites and ticks of these lizards are poorly known, despite some of these chelicerates being vector pathogens of humans and wildlife. Here we document and curate previously known data on ectoparasitic Acari of rock lizards and, based on our extensive survey, provide an annotated list of these ectoparasitic arthropods (six tick species, one macronyssid species, and seven chigger species). We also provide new host records (Ixodes ricinus on Darevskia caucasica, D. dryada, D. mixta, and D. szczerbaki; Haemaphysalis sulcata on D. rudis; Odontacarus saxicolis on D. brauneri); and new geographical records (O. saxicolis in Russia and Georgia)

    This is the final version. Available on open access from Nature Research via the DOI in this recordData availability: All collapsed and paired-end sequence data for samples sequenced in this study are available in compressed fastq format through the European Nucleotide Archive under accession number PRJEB44430, together with rescaled and trimmed bam sequence alignments against both the nuclear and mitochondrial horse reference genomes. Previously published ancient data used in this study are available under accession numbers PRJEB7537, PRJEB10098, PRJEB10854, PRJEB22390 and PRJEB31613, and detailed in Supplementary Table 1. The genomes of ten modern horses, publicly available, were also accessed as indicated in their corresponding original publications57,61,85-87.NOTE: see the published version available via the DOI in this record for the full list of authorsDomestication of horses fundamentally transformed long-range mobility and warfare. However, modern domesticated breeds do not descend from the earliest domestic horse lineage associated with archaeological evidence of bridling, milking and corralling at Botai, Central Asia around 3500 BC. Other longstanding candidate regions for horse domestication, such as Iberia and Anatolia, have also recently been challenged. Thus, the genetic, geographic and temporal origins of modern domestic horses have remained unknown. Here we pinpoint the Western Eurasian steppes, especially the lower Volga-Don region, as the homeland of modern domestic horses. Furthermore, we map the population changes accompanying domestication from 273 ancient horse genomes. This reveals that modern domestic horses ultimately replaced almost all other local populations as they expanded rapidly across Eurasia from about 2000 BC, synchronously with equestrian material culture, including Sintashta spoke-wheeled chariots. We find that equestrianism involved strong selection for critical locomotor and behavioural adaptations at the GSDMC and ZFPM1 genes. Our results reject the commonly held association between horseback riding and the massive expansion of Yamnaya steppe pastoralists into Europe around 3000 BC driving the spread of Indo-European languages. This contrasts with the scenario in Asia where Indo-Iranian languages, chariots and horses spread together, following the early second millennium BC Sintashta culture

    A Review of Ixodid Ticks (Acari: Ixodidae) Associated with <i>Lacerta</i> spp. (Reptilia: Lacertidae) from the Caucasus and Adjacent Territory

    Based on a literature review, as well as on our own data, 14 ixodid tick species belonging to 5 genera were registered for the lizard hosts of the genus Lacerta (L. agilis, L. media, and L. strigata) in the Caucasus and the adjacent territories: Haemaphysalis sulcata, Haem. punctata, Haem. parva, Haem. caucasica, Haem. concinna, Haem. inermis, Ixodes ricinus, I. redikorzevi, Dermacentor marginatus, D. reticulatus, Hyalomma marginatum, Rhipicephalus bursa, Rh. rossicum, and Rh. turanicum. Tick species Haem. caucasica were recorded from Armenia for the first time. Our findings of Haem. punctata represent the first record of this species for Chechnya, Ingushetia (Russia), Armenia, and Azerbaijan. Most of the parasite species are associated with L. agilis (13) and L. strigata (12); L. media is a host of 6 tick species. Data on the infestation of Lacerta spp. by four tick species from our material (I. ricinus, Haem. punctata, Haem. caucasica, and Hyal. marginatum) are presented in the article. In addition, our article contains information on the range of infections associated with the above tick species. Castor bean tick I. ricinus (236 specimens), the most represented species in our collection, parasitizes all available terrestrial vertebrates including humans and can be vector of many various pathogens, so our study provides significant epidemiological information

    New findings of spinturnicid mites (Mesostigmata: Gamasina: Spinturnicidae) from the Caucasus

    The Caucasus is a large region in Eurasia consisting of four countries: Russia, Georgia, Azerbaijan, and Armenia. Although it is one of the biodiversity hotspots in the world, the bat ectoparasite fauna has been poorly studied. To promotionally fill in the gaps regarding bat ectoparasites, we conducted five field surveys on bats and their ectoparasites at nine localities within the region between April 2016 and March 2021. Eight species and subspecies of spinturnicid mites were recorded over the surveys: Eyndhovenia euryalis oudemansi, Spinturnix acuminata acuminata, S. emarginata, S. myoti, S. nobleti, S. plecotina, S. psi, and S. punctata. Among them, three species, Spinturnix emarginata, S. nobleti and S. punctate, are newly recorded from the Caucasus region, and one each of subspecies and species, Eyndhovenia euryalis oudemansi and S. plecotina, are newly recorded from Georgia. In addition, Myotis tschuliensis was recorded as a new host species of S. myoti. © 2021 Elsevier B.V

    A checklist of bat-associated macronyssid mites (Acari: Gamasina: Macronyssidae) of Russia, with new host and geographical records

    The family Macronyssidae (Acari: Mesostigmata) comprises mostly obligate blood-sucking ectoparasites of bats (Mammalia: Chiroptera) and some other animals, such as small mammals, reptiles and birds. Here, we document and curate previously known data, and, based on our extensive survey, provide this article of bat-associated macronyssid mites of the Russian Federation. We record a total of 24 mite species belonging to 4 genera (Ichoronyssus, Macronyssus, Steatonyssus, and Cryptonyssus). Twenty-seven new host-parasite associations are reported. In addition, were provide data on five major Russian regions, for which bat-associated mite records were lacking
