Taggstrålar i ryggfenan (totalt) : 2; Mjukstrålar i ryggfenan (totalt) : 7; Mjukstrålar i analfenan: 12 - 14; Ryggkotor: 52. Distinguished from its congeners by a unique combination of the following characters: head length 30.8-32.4% SL, length of caudal peduncle 15.3-16.1% SL, depth of caudal peduncle 7.8-8.5% SL, dorsal to adipose distance 4.0-7.0% SL, eye diameter 11.5-12.3% HL, 52 vertebrae, and olive green body with orange fins (Ref. 41209).
Body shape (shape guide): elongated; Cross section: compressed.
Inhabits rivers. In Nagarjunasagar reservoir, this species contributed to the commercial fishery to the extent of 1 to 3 t per annum during 1976-80 (Ref. 43629).
