Description

A new spined loach, Cobitis beijingensis, is described from Beijing, China. The new species can be distinguished from other congeners by a combination of characters: 1) Lamina circularis on pectoral fin of male elongated, posterior margin slightly serrated; 2) possessing 14–18 (mode 15) pre-pelvic myotomes; 3) pelvic fin inserted below 3rd–5th branched dorsal-fin ray; 4) total vertebrae 4+ 36–38 (mode 37); 5) L2 of the Gambetta's pattern does not exist or is fused with L1. The molecular phylogenetic analyses based on mitochondrial Cyt b also support C. beijingensis to be a new species.
