Abstract:Partial sequences of mitochondrial 12S rRNA gene from 6 civets and Cyt b gene sequences from 4 species were sequenced. The combined data was 755bp long, containing 191 variable sites, 90 parsimony informative sites. There were 120 variable sites in Cyt b gene sequence (375 bp), and it showed higher nucleotide variation (32 %) than 12S rRNA gene (370 bp), which only had 70 variable sites (18.4 %). Molecular phylogenetic tree (NJ and ML) supported that Viverrine was polyphyletic, and implied spotted linsang (Prionodon pardicolor) perhaps was basal and mostly specified to other Viverridae species in China. Meanwhile, Large Indian civet (Viverra zibetha), small Indian civet (Viverricula indica) clustered together, Masked palm civet (Viverricula indica), Binturong (Arctictis binturong) clustered together and they constituted monophyletic group respectively. These were consistent with traditional taxonomy arrangement.
