On the identity of Barbus (=Hypselobarbus) gracilis Jerdon (1849) and description of a new species of Hypselobarbus (Cypriniformes: Cyprinidae) from Western Ghats, peninsular India

Abstract

Barbus (= Hypselobarbus ) gracilis is resurrected from synonymy with Barbus (= Hypselobarbus ) micropogon . The elevation of this species is based on the original descriptions by Jerdon and Day, and new data provided herein from topotypes. Hypselobarbus gracilis is diagnosed from H. micropogon in having fewer circumpeduncular and circumferential scale rows and a few morphometric characters. A new species with a long snout is described from Kali River, Karnataka, India. This new “mussullah-like” species, Hypselobarbus nasutus is diagnosed from H. musullah in having fewer lateral line and circumferential scale rows and more transverse breast scale rows.
