Tanichthys kuehnei, new species, from Central Vietnam (Cypriniformes: Cyprinidae)

Abstract

Tanichthys kuehnei, new species, is described from a stream in the Bach Ma Mountains in Hue Province in Central Vietnam. The new species differs from its congeners by having more branched rays in anal fin (9 1/2 vs. 7-8 1/2 in T. micagemmae and 8 1/2 in T. albonubes and T. thacbaensis).

Morphological and genetic characters suggest it to be closer related to T. micagemmae, the only other species of Tanichthys known from Central Vietnam. Tanichthys kuehnei differs from T. micagemmae by having a white anal-fin margin (vs. red).
