“…In most cases, such patterns are attributable to adaptive introgression of mtDNA, demographic disparities, and sex-biased asymmetries; in some cases they found evidence for hybrid zone movement or human agency. Discordant patterns of variation between mitochondrial and nuclear DNA have been reported in at least six other families of bats (Nesi et al 2011;Furman et al 2014;Naidoo et al 2016;Hassanin et al 2018;Demos et al 2019a;Gürün et al 2019). Gürün et al (2019) implicated the role of sex-biased dispersal in causing such discordance, male dispersal spreading nuclear variation farther and faster than the movement of mitochondria.…”

The Old World leaf-nosed bats (Hipposideridae) are aerial and gleaning insectivores that occur throughout the Paleotropics. Both their taxonomic and phylogenetic histories are confused. Until recently, the family included genera now allocated to the Rhinonycteridae and was recognized as a subfamily of Rhinolophidae. Evidence that Hipposideridae diverged from both Rhinolophidae and Rhinonycteridae in the Eocene confirmed their family rank, but their intrafamilial relationships remain poorly resolved. We examined genetic variation in the Afrotropical hipposiderids Doryrhina, Hipposideros, and Macronycteris using relatively dense taxon-sampling throughout East Africa and neighboring regions. Variation in both mitochondrial (cyt-b) and four nuclear intron sequences (ACOX2, COPS, ROGDI, STAT5) were analyzed using both maximum likelihood and Bayesian inference methods. We used intron sequences and the lineage delimitation method BPP-a multilocus, multi-species coalescent approach-on supported mitochondrial clades to identify those acting as independent evolutionary lineages. The program StarBEAST was used on the intron sequences to produce a species tree of the sampled Afrotropical hipposiderids. All genetic analyses strongly support generic monophyly, with Doryrhina and Macronycteris as Afrotropical sister genera distinct from a Paleotropical Hipposideros; mitochondrial analyses interpose the genera Aselliscus, Coelops, and Asellia between these clades. Mitochondrial analyses also suggest at least two separate A peer-reviewed open-access journal B. D. Patterson et al. / ZooKeys 929: 117-161 (2020) 118 colonizations of Africa by Asian groups of Hipposideros, but the actual number and direction of faunal interchanges will hinge on placement of the unsampled African-Arabian species H. megalotis. Mitochondrial sequences further identify a large number of geographically structured clades within species of all three genera. However, in sharp contrast to this pattern, the four nuclear introns fail to distinguish many of these groups and their geographic structuring disappears. Various distinctive mitochondrial clades are consolidated in the intron-based gene trees and delimitation analyses, calling into question their evolutionary independence or else indicating their very recent divergence. At the same time, there is now compelling genetic evidence in both mitochondrial and nuclear sequences for several additional unnamed species among the Afrotropical Hipposideros. Conflicting appraisals of differentiation among the Afrotropical hipposiderids based on mitochondrial and nuclear loci must be adjudicated by large-scale integrative analyses of echolocation calls, quantitative morphology, and geometric morphometrics. Integrative analyses will also help to resolve the challenging taxonomic issues posed by the diversification of the many lineages associated with H. caffer and H. ruber.

Abstract. In 1966, Robert William Hayman, Xavier Misonne and Walter Verheyen published their listing of the Congolese, Rwandan and Burundian bat specimens in the collections in the museums of Tervuren, Brussels, Geneva, London and New York. In the fifty years that have passed since, some major changes have been introduced in the taxonomy of the Chiroptera: new species have been discovered, species have been split off, species have been moved to other genera, and additional material has been collected. We re-evaluated the data presented by Hayman et al., and supplemented this with specimen records found in the literature and in online catalogs. This resulted in 136 species, represented by 20 231 specimens (compared to 113 species and 8567 specimens originally). When available, we also recorded additional information such as locality, sex and age, collector, collection date and preservation type of the voucher specimen. The distribution maps of the Congolese taxa are revised to represent the current taxonomy, and are presented in perspective against the taxon's Species Distribution Model to assess species distribution on the African continent. Additionally, an updated key to the various taxa is presented.

11Molecular data are now commonly used in taxonomy for delimiting cryptic species. In 12 the case of giraffes, which were treated as a single species (Giraffa camelopardalis) during 13 half of a century, several molecular studies have suggested a splitting into four to seven 14 species, but the criteria applied for taxonomic delimitation were not fully described. 15In this study, we have analysed all multi-locus DNA sequences available for giraffes 16 using multispecies coalescent (MSC: *BEAST, BPP and STACEY), population genetic 17 (STRUCTURE, allelic networks, haplotype network and bootstrapping) and phylogenetic 18 (MrBayes, PhyML, SuperTRI) methods to identify the number of species. Our results show 19 that depending on the method chosen, different taxonomic hypotheses, recognizing from two 20 to six species, can be considered for the genus Giraffa. Our results confirm that MSC methods 21 can lead to taxonomic over-splitting, as they delimit geographic structure rather than species.22 The 3-species hypothesis, which recognizes G. camelopardalis sensu strico, G. giraffa, and G. 23 tippelskirchi, is highly supported by phylogenetic analyses and also corroborated by most 24 population genetic and MSC analyses. The three species show high levels of nucleotide 25 divergence in both nuclear (0.35-0.51 %) and mitochondrial sequences (3-4 %), and they are 26 characterised by 7 to 12 exclusive synapomorphies (ES) detected in nine of the 21 nuclear 27 introns analysed for this study. By contrast, other putative species, such as G. peralta, G. 2 28 reticulata, G. thornicrofti or G. tippelskirchi sensu stricto, do not exhibit any ES in nuclear 29 genes. 30 A robust mito-nuclear conflict was found for the position and monophyly of G. giraffa 31 and G. tippelskirchi, which is explained firstly by a mitochondrial introgression from Masai 32 giraffe to southeastern giraffe during the Pleistocene, and secondly, by gene flow mediated by 33 male dispersal between southern populations (subspecies G.g. giraffa and G.g. angolensis). 34 35 37 38 46 (cytochrome c oxidase subunit 1), have been intensively used for species delimitation [3-4]. 47 However, numerous molecular studies have revealed that the mitochondrial tree may deviate 48 from the species tree. Indeed, the maternal inheritance of the mtDNA genome can be 49 misleading for species delimitation because females and males have generally different 50 dispersal behaviours (female philopatry versus male dispersal) [5,6], and because interspecific 51 hybrid females are generally fertile, whereas hybrid males are often sterile (Haldane's rule), 52 facilitating mitochondrial introgression between closely related species [7-9]. To overcome 3 53 these limitations, most recent taxonomic studies dealing with the delimitation between cryptic 54 mammal species have focused on multi-locus datasets [10-12], as the use of multiple 55 independent DNA markers has been shown to provide a strong and reliable signal for 56 deciphering relationships among closely related taxa [13-14]. However, i...
