Garra biloborostris, a new labeonine species from north-eastern India (Teleostei: Cyprinidae)

Abstract

Garra biloborostris, a new labeonine species is described from the Kanamakra River of the Brahmaputra River basin in Assam. It can be distinguished from its congeners of northeast India in having a unique combination of the following characters: a proboscis represented by two separate and slightly elevated arch-shaped lobes, each lobe with three acanthoid tubercles on its anterodorsal marginal aspect; bulgy lateral surface of the snout giving a lobe like appearance; a prominent knob-like transverse lobe with 10 – 16 small- to medium-sized acanthoid tubercles; 30 + 3 lateral line scales; 8½ branched dorsal fin rays; and 5½ branched anal fin rays.
