摘要: Based on molecular data for mitochondrial (Cyt b, COI) and nuclear (IRBP, GHR) genes, morphological examinations of museum specimens, we examined diversity, species boundaries, relationships within between the murine genera Chiromyscus Niviventer. Phylogenetic patterns recovered demonstrate that Niviventer sensu lato is not monophyletic but instead includes chiropus, only previously recognized Chiropus. To maintain Chiropus as lineages, scope definition genus revised to include at least three distinct species: chiropus (the type Chiromyscus), langbianis (previously regarded a Niviventer), new species, described in this paper under name thomasi sp. n.
