Morphology | Morphometrics
soft rays: 52 - 64. Diagnosis: pectoral-fin spine strongly denticulate posteriorly; barbels very short, inner mandibular barbels often rudimentary; posterior nostrils as close as or closer to each other than the anterior ones; 52-64 branched anal-fin rays and 10-16 gill rakers on lower limb of first gill arch; adipose fin always present (Ref. 57127, 81643).
Coloration: no information available on colour pattern in life (Ref. 57127, 81643). Preserved specimens: head and back dark brown; traces of lateral bands visible, one above lateral line, another one at anal-fin base and a third along anal-fin margin; belly often spotted/speckled; base and margin of caudal fin greyish (Ref. 57127, 81643).
Oviparous, eggs are unguarded (Ref. 205).
