Abstract: A new cyprinid fish, Hypselobarbus kushavali, is described from Kali River, Karnataka, India. Hypselobarbus kushavali is diagnosed from its closest congener, H. dobsoni, by having more upper transverse scale rows, more circumferential scale rows and more lateral line to pelvic scale rows, and from H. bicolor and H. jerdoni by having fewer lateral-line and fewer circumpeduncular scale rows. Diagnostic features for H. kushavali are also provided relative to other species of the genus. Keywords: Cyprinidae, Hypselobarbus kushavali, Distribution, Taxonomy.

Etymology: The species epithet kushavali is a noun derived from the village Kushavali where the Kali

River originates. Distribution: This species is currently known only from Kali River, Karnataka (Fig. 3). Habitat: Hypselobarbus kushavali is associated with riverine habitats where they preferdeep pools and riffles with slow to moderately fast current. Substrate type is mostly large boulders. The type locality for H. kushavali is presented in Figure 4. Conservation: Large-sized barbs of Hypselobarbus and Tor and some catfishes are common in upstream areas of the Kali River andArchive in the Bommanahalli, of SID Supa and Bottom dams where they occur in large quantities. However, the fishing pressure in these areas is high and this may lead to the depletion of the native fish species. Remarks: Hypselobarbus kushavali is closely related Fig.3.
