Identification Clarias species are characterized by having an elongated body; a soft rayed dorsal fin extending to, or nearly to, the caudal fin base; a soft rayed anal fin extending from just behind the anus to the caudal fin base; pectoral fins each with a serrated anterior bony spine; head depressed, covered largely by firmly sutured, surface sculptured bony plates forming a protective helmet; four pairs of flagellate barbels (nasals, maxillaries, inner and outer mandibulars); air breathing organs derived from the 2nd and 4th epibranchials within a superbranchial chamber.

Can be distinguished from congeners in the region by a combination of: smooth pectoral spine, 68-78 dorsal-fin rays, 58-64 anal-fin rays, a moderately broad supraoccipital process, and a distinct pattern of white spots on the sides of the body.
Sexing Males have an elongate genital papilla.
