Épines dorsales (Total) : 2; Rayons mous dorsaux (Total) : 7; Rayons mous anaux: 12 - 13; Vertèbres: 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).
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.
