Abstract:
Triplophysa qini, a new stygobitic fish, is described from two subterranean pools (in the Wu-Jiang of the upper Chang-Jiang basin) located in Wulong and Fengdu counties, Chongqing City, Southwest China. It exhibits a concave distal margin of the dorsal fin and absence of nasal barbels; two characters that combined differentiate it from all congeners of the eyeless group except T. qiubeiensis. The new species differs from T. qiubeiensis in the number of branched dorsal-fin rays (9 vs. 8) and in the shorter head. The specific status of T. qini is confirmed by its significant sequence divergence for the cyt b gene with sampled congeneric species, particularly those coexisting in the mid-upper Chang-Jiang basin, and by its monophyly recovered in a cyt b gene-based phylogenetic analysis.
