Morphologie | Morphométrie
Épines dorsales (Total): 2; Rayons mous dorsaux (Total): 5; Rayons mous anaux: 10 - 11; Vertèbres: 32 - 34. A member of the Akysis variegatus group which differs from its congeners in possessing a short adipose-fin base (13.0-15.4% SL), a steeply-sloping predorsal profile and a unique combination of the following characters: pectoral spine length 16.1-17.4% SL, body depth at anus 15.7-17.0% SL, eye diameter 9-10% HL, anterior nostrils separated by more than half of interorbital distance, serrations on posterior edge of pectoral spine, and emarginate caudal fin (Ref. 56231).
Found among leaf litter in a swift-flowing stream with a sandy bottom (Ref. 56231).
