Taggstrålar i ryggfenan (totalt) : 2; Mjukstrålar i ryggfenan (totalt) : 7; Mjukstrålar i analfenan: 12 - 13; Ryggkotor: 44 - 45. Distinguished from its congeners by the following unique combination of characters: head length 32.7-33.5% SL, head depth 14.2-15.3% SL, depth of caudal peduncle 7.5-8.8% SL, eye diameter 11.9-12.3% HL, a pattern of dark dots arranged in vertical columns on the sides of the body, a convex snout and a broad, shallowly incised humeral process (Ref. 41209).
Body shape (shape guide): elongated; Cross section: compressed.
Inhabits rivers and ponds in plains and submontane regions (Ref. 41236). It is usually dug out from the bottom of ponds where they lie buried in soft, wet clay.
