Abstract: We obtained IRBP,12S rRNA,and Cytochrome b (Cyt b)sequences of the leopard cat (Prionailurus bengalensis) from Korea,and these sequences were compared to the corresponding sequences of the leopard cat and the Iriomote cat,P. iriomotensis,obtained from GenBank,to reexamine genetic divergence of Korean leopard cats from both other leopard cats and Iriomote cats. First,from IRBP,12S rRNA,and Cyt b sequencing analyses with 18 Korean leopard cats,six alleles, one haplotype,and three haplotypes were identified,respectively,and we concluded that past bottleneck events that occurred in Korean leopard cats,is a plausible cause for the differential loss of genotypes detected in this study. Based on Cyt b sequence analysis we confirmed that East Asian leopard cats form a clade,and we found that former and present Cyt b sequencing results support a previous classification that recognized P bengalensis from East Asia as P. euptilurus. Finally,we detected identical sequences in the IRBP and 12S rRNA genes between specimens of P bengalensis from Korea and those of P. iriomotensis,supporting widespread treatment of the Iriomote cat as conspecific with P. bengalensis.
