摘要

Until 2008, three species of fossorial moles (tribe Talpini, Talpidae, Lipotyphla, Mammalia) were recognised in Vietnam: Euroscaptor longirostris from the northern highlands, E. parvidens from the southern Annamese mountains and Mogera latouchei from the northern lowlands. Recently, a new species (Eursocaptor subanura) was described from northern Vietnam. This new mole is externally similar to E. parvidens, but the skull and dental characters are rather similar to E. longirostris. In this study, we determined the complete mitochondrial cytochrome b (Cytb; 1140 bp), partial mitochondrial 12S ribosomal RNA (12S; ca. 850 bp) and partial nuclear recombination activating gene 1 (Rag1; 1010 bp) gene sequences of 19 specimens of E. subanura collected from three localities in northern Vietnam and estimated the phylogenetic relationships among the Southeast Asian moles. Our results strongly support the full species status of E. subanura and that it is a sister taxon to E. parvidens of central Vietnam, but not E. longirostris of northern Vietnam. Although we analysed samples from only three localities, intraspecies diversity in E. subanura was lower than in the other two species. These results suggest that E. subanura diverged from E. parvidens and that it is a relict species that survived past climatic changes.
