A new species of the subfamily Labeoninae,
Garra nujiangensis
Chen and Yang, sp. nov. is recognized from a secondary branch of Nujiang River (upper Salween) in Zhenkang county, Yunnan province, China. It can be distinguished from other beardless
Garra species by the following combination of characters: 12 − 14 circumpeduncle scales; 48 − 50 lateral- line scales; a pair of rudimentary rostral barbels present in little individuals; 8 − 9 branched dorsal-fin rays; 5 − 6 scales between dorsal-fin origin and lateral line and 3 − 4 scales between pelvic-fin origin and lateral line; caudal peduncle relatively stouter; length between snout tip to posterior margin of eye longer than body depth at anal fin origin; head length longer than body depth at dorsal fin origin; prepelvic length 50.0% − 53.7% of standard length; pre-anus length 58.9% − 63.9% of standard length; body width 16.7% − 19.6% of standard length; body depth at dorsal fin 19.2% − 22.6% of standard length. The present study also verified that the presence of tiny barbells is a juvenile character in some beardless
Garra species, such as
G. nujiangensis and
G. alticorpora.
