- Аннотация: The phylogeographic structure of the endemic white-toothed shrews of Vietnam, which belong to the Crocidura kegoensis–C.zaitsevi group, was assessed using mitochondrial and nuclear data. Specimens from 12 localities across Vietnam, includingthe holotypes of C. kegoensis and C. zaitsevi, were evaluated according to the complete mitochondrial cytochrome b (cytb)gene and fragments of eight independent nuclear loci. The results of molecular analyses revealed the conspecificity of C.kegoensis and C. zaitsevi. Therefore, the name Crocidura zaitsevi Jenkins et al., 2007, can be considered as a synonym of C.kegoensis Lunde et al., 2004, which has a complex phylogeographical structure. The analysis of cytb proved the existence ofdistinct mtDNA lineages in C. kegoensis: lineage A, which is distributed in the northern and central parts of the AnnamiteRange; and lineage B, which is only found in the south parts of the species range. Nuclear data support the differentiationbetween northern and southern populations, with the position of the central populations remaining unresolved. The estimateddivergence times of the main mitochondrial lineages indicate that the Vietnamese endemic group, C. kegoensis−C. zaitsevi,represents a young taxon, with all radiation events occurring in the cooling periods of the Pleistocene.
