- Аннотация: We present new insights into the diversity of the Asiatic water shrews of Indochina based on analyses of complete mitochondrial cytochrome b gene and fragments of three nuclear loci: apolipoprotein B, recombination-activating gene 1 and interphotoreceptor retinoid-binding protein. A new, highly divergent genetic lineage of Chimarrogale was found in southern Vietnam, and this lineage includes specimens from the provinces of Kon Tum, Dak Lak, and Lam Dong. The latter findings represent the newest and southernmost records of Chimarrogale in Indochina. Morphological analysis classified the specimens from southern Vietnam as C. varennei proper, which is restricted to that region, whereas the polymorphic C. himalayica, which contains at least four cytochrome b haplogroups, occurs in central and northern Vietnam and southern China. Our finding of a distinct C. varennei lineage that is closely related to the C. platycephalus + C. leander clade suggests the existence of an unknown glacial refuge in southern Vietnam (Tay Nguyen Plateau). Considering the phylogenetic reconstruction placed the Bornean C. phaeura as the deepest branch among Chimarrogale sensu lato as well as its high genetic divergence (~15% for cytochrome b) and geographical isolation, we suggest that C. phaeura be placed into a separate genus, Crossogale Thomas, 1921. This genus should also include C. sumatrana (Sumatra) and C. hantu (Peninsular Malaysia). Finally, a new classification system for Asiatic water shrews is proposed.
