This species is distinguished by the following characters: body oval, flat and asymmetric; eyes located on right side of head, except in reversed individuals (Ref. 57416). Upper eye less than its own diameter from dorsal profile of head (Ref. 4710). Anterior nostril on blind side not enlarged (Ref. 4710, 57416), but surrounded by small rim (Ref. 57416). Its distance from front margin of head 1.5-1.9x in its distance from cleft of mouth; anterior nostril on eyed side with backward-pointing tube not or only barely reaching front border of lower eye (Ref. 4710). Preopercle covered by skin and opercle entirely scaled; mouth arched and inferior; dorsal and anal fins lacking spinous rays and united to caudal fin by well-developed membrane, but caudal peduncle distinct; dorsal fin originating on horizontal axis through upper eye; pectoral fin on eyed side asymmetrical, with 7-10 rays, and on blind side slightly shorter; straight part of lateral line visible, supratemporal part slightly arched above eyes; body covered with rectangular ctenoid scales (Ref. 57416).

Description: snout rounded ending in a fleshy lobe; head covered with small villosities (Ref. 57416). Colouration: eyed side more or less dark greyish-brown, with broad and diffuse dark spots; dorsal and anal fins showing same ground colour as body; pectoral fins with blackish spot on distal half; posterior part of caudal fin darker; blind side whitish (Ref. 57416).
