Mjukstrålar i ryggfenan (totalt) : 7; Mjukstrålar i analfenan: 9; Ryggkotor: 40. This species is distinguished from its congeners inhabiting the Chindwin basin of Manipur by the following set of characters: a pair of short rudimentary maxillary barbe; mandibular knob absent; length of origin of dorsal fin to the upper end of caudal fin lobe is longer than the distance between the origin of dorsal fin to the anterior margin of nares; blue black lateral bands 8-10; anterior base of caudal fin with a round blue black spot which is overlap by the last vertical band; dorsal fin with a black midtransverse band; distinct red colouration of anal fin, depth of caudal peduncle 9.2-9.9% SL; eye diameter 6.3-8.5% SL; post dorsal length 72.1-78.5% SL; head length 18.7-24.2% SL; head depth at occiput 17.2-21.2% SL; and at eye 64.6-70.0% HL; snout length 30.8-37.2% HL; interorbital width 32.2-35.8% HL and width of head at neck 42.6-48.5% HL (Ref. 126981).
Found in fast-flowing stream and river with clear water, gravel or cobble bottoms; associated with Schistura manipurensis, Pethia meingangbii, Glyptothorax granulus, Channa marulius, Rasbora ornatus, Devario aequipinnatus, Acanthocobitis zonalternans, Botia histronica (Ref. 126981).
