Abstract	Background: Biodiversity surveys are essential for both academic research and conservation. Integrative approaches that combine morphological, genetic and acoustic aspects for species identification can provide reliable information in taxonomy and evolution. This is especially relevant for those groups with a high degree of cryptic diversity such as bats. New information: Here, we present the results from a field survey carried out in the Cuc Phuong National Park (CPNP) during 2019 as part of the VIETBIO project and from the examination of specimen collections preserved at the museums of CPNP and the Institute of Ecology and Biological Resources (IEBR). In addition, we include an annotated species list, based on this survey and a literature review. We here confirm that CPNP is home to at least 47 bat species belonging to 23 genera and seven families. We recorded ten of these bat species during our field survey. Obtained data in genetics (sequencing a fragment of the mitochondrial gene COI) supported the morphological identification of the recorded species for which we were able to produce these data. In addition, we include echolocation recordings obtained during our field training with the hope that they may contribute valuable insights to future work concerning the surveyed species. Results from the field survey represent a relevant contribution to biodiversity assessment efforts and, thus, support conservation and management efforts to maintain bat diversity in Vietnam.

Abstract	Located within the Phong Nha-Ke Bang National Park, Central Vietnam, Son Doong Cave is the world’s largest cave and has become one of the most famous sites for caving tourists and scientists worldwide. It contains highly diverse landscapes and ecosystems with special value in many natural aspects including biodiversity. Bat species are usually regarded as key and fascinating dwellers in cave ecosystems. We recently conducted a bat survey in Son Doong Cave in May 2022 for an initial understanding of the bat species inhabiting this special cave. Bats were captured using mist nets. Echolocation calls were recorded and analyzed using the PCTape system and Batman and Selena software, respectively. Results from the survey confirmed that Son Doong Cave is a home for at least six echolocating bat species of five genera and four families: Hipposideridae (Aselliscus stoliczkanus, Hipposideros scutinares), Rhinolophidae (Rhinolophus thomasi), Molossidae (Mops plicatus) and Vespertilionidae (Myotis pilosus and Myotis cf. muricola). Of these five species, H. scutinares and M. pilosus are listed as globally “vulnerable” by the IUCN Red List of Threatened Species. Among the six captured and recorded species from the Son Doong Cave, each species is clearly distinguishable from the others in terms of morphological features, echolocation call structure and frequencies.

Abstract	Chromosomal variation among closely related taxa is common in both plants and animals, and can reduce rates of introgression as well as promote reproductive isolation and speciation. In mammals, studies relating introgression to chromosomal variation have tended to focus on a few model systems and typically characterized levels of introgression using small numbers of loci. Here we took a genome-wide approach to examine how introgression rates vary among four closely related horseshoe bats (Rhinolophus pearsoni group) that possess different diploid chromosome numbers (2n=42, 44, 46, and 60) resulting from Robertsonian (Rb) changes (fissions/fusions). Using a sequence capture we obtained orthologous loci for thousands of nuclear loci, as well as mitogenomes, and performed phylogenetic and population genetic analyses. We found that the taxon with 2n = 60 was the first to diverge in this group, and that the relationships among the three other taxa (2n=42, 44 and 46) showed discordance across our different analyses. Our results revealed signatures of multiple ancient introgression events between the four taxa, with evidence of mitonuclar discordance in phylogenetic trees and reticulation events in their evolutionary history. Despite this, we found no evidence of recent and/or ongoing introgression between taxa. Overall, our results indicate that the effects of Rb changes on the reduction of introgression are complicated and that these may contribute to reproductive isolation and speciation in concert with other factors (e.g. phenotypic and genic divergence).

Abstract	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.

Abstract	Eyndhovenia is one of the twelve genera of Spinturnicidae which are highly specialised parasites of bats. Previously known hosts of this genus comprised 17 species of Old World bats: Eptesicus serotinus, Hipposideros larvatus, Miniopterus schreibersi, Myotis blythi, M. emarginatus, Pipistrellus pipistrellus, P. gaisleri, Rhinolophus axillaris, R. blasii, R. clivosus, R. cornutus, R. euryale, R. ferrumequinum, R. hipposideros, R. megachyllus, R. mehelyi, R. rouxi. Within Asia, Eyndhovenia was only recorded from two countries, China and Thailand. Between 2018 and 2020, we conducted a series of bats surveys and recorded of this genus from intermediate horseshoe bat, Rhinolophus affinis, in Vietnam. The present study exhibits the new record in both parasitological and geographical aspects.

Abstract	Recently diverged taxa are often characterised by high rates of introgressive hybridization and incomplete lineage sorting, both of which can complicate phylogenetic reconstructions of species histories. Here we use a sequence capture approach to obtain genome-wide data to resolve the evolutionary relationships, and infer the extent and timescale of hybridization and introgression events, among six recently diverged taxa of the horseshoe bat species complexes Rhinolophus sinicus and R. thomasi. We show that two different methods of species tree reconstruction applied to a set of ~1500 nuclear loci all recover species trees with similar topologies, differing from the previous phylogeny based on two nuclear loci. By comparing the tree topology obtained from the nuclear loci with that inferred from the mitochondrial genome, we observed at least three cases of conflict, each of which likely results from past introgression. Of these, the occurrence of a highly similar mitogenome sequence shared by individuals of two taxa in a sympatric region points to very recent mtDNA introgression. The other cases are characterised by greater divergence and strong phylogeographic structure among putative introgressed individuals and their source populations, and thus likely reflect more ancient hybridization events. These results also suggest that two of the subspecies (R. s. septentrionalis and the undescribed taxon R. s. ssp) are likely to represent full species, warranting full taxonomic descriptions. This work adds a growing number of studies showing the potential problems of relying solely on mitochondrial sequences, or a limited number of loci, to infer phylogenetic relationships among recently diverged taxa.

Abstract	To better understand the distribution and host-parasite relationships, we explored 12 large regions of Russia and recorded new bat fleas (Insecta: Siphonaptera: Ischnopsyllidae) for Dagestan, Bashkiria, Mordovia, Khakassia and Buryatia Republics. Also we curate previously known data and registered new host-parasite associations for species belonging to genus Ischnopsyllus (Ischnopsyllus octactenus and I. variabilis ex Pipistrellus pygmaeus, I. intermedius ex Hypsugo savii, I. variabilis ex Myotis dasycneme, I. hexactenus ex Murina hilgendorfi) and species Myodopsylla trisellis. One of the associations we recorded in Altai republic is particularly interesting (Myodopsylla trisellis – Myotis blythii). Further investigation is required to study vector role of bat fleas and the effects of flea parasitism on their natural hosts.
