Color: In male color of head and body uniformly dark, chocolate brown, or abdomen a little paler. Only spot or marking a black spot smaller than eye on upper half of pectoral base. Pectoral and caudal pale in young (said to be yellow in life) but also brown in half grown and adults. Some with lower half of caudal dark, upper half pale. Dorsal same color as body except last two rays which may be pale. First few anal rays same color as body, rest of anal nearly black. Pelvics uniform with body. Female color like male except abdomen a little lighter. Juveniles often bright yellow

No trace of crest on head in either sex. Nasal, supra orbital and nuchal cirri present, simple, slender, pointed and identical except for length, nasal about 1/2 pupil in length, supra orbital about 1/3 eye in length, nuchal a little shorter than supra orbital. Snout evenly rounded and forehead receeding. Upper lip markedly crenulate, but in a different manner than Salarias, each crenulation a little lappet nearly as long as wide, 20 to 25 in number, widely (and sometimes irregularly) spaced so that interval between them may be wider than lappet. Lower lip smooth. No canines above or vomerine teeth. A tiny, blunt canine below. Labial teeth, both above and below, numerous, movable and typically Salariin. Depth 3.2-3.5. Head 3.8-4.0. Lateral line curving down behind pectoral and continuing to base of caudal with one pore on each metamere. Dorsal with no trace of notch or emargination, increasing steadily in height to last few rays, first few spines buried in loose membrane, last two rays shortened, but the few before them (in larger specimens) much elongated, reaching well past middle of caudal when fin is depressed, last ray bound fully, or almost so, to caudal, the membrane reaching to first principal ray. None of caudal rays branched even in large specimens, middle rays long and attenuated, fin being 2.6 to 2.9 in length in adults. Caudal and last few dorsal and anal rays increasing markedly with age, all being brief and rounded in young. Two anal spines of male short, bearing thick, rounded, fleshy pads with outer surface covered by irregularly transverse grooves, proximal 2/3 of first ray similarly fleshy and grooved, second ray sometimes a little fleshy and grooved, first 2 or 3 rays particularly elongate, fleshy, with membrane between them excised nearly to base, other rays with only tips free and graduated in length to the third from last, which is extended out to match the dorsal, last two rays shortened, last day bound to caudal peduncle by a membrane which reaches to the first small caudal rays. Dorsal, anal and caudal not so much elongated in female, first anal rays not lengthened and modified, first spine buried in genital papilla. Pectoral shorter than head by length of snout. two pelvic rays fleshy, of nearly equal length, spine very short, scarcely emerging from membrane, and not visible without dissection. Dorsal spines (total): 11; Dorsal soft rays (total): 18 - 20; Anal soft rays: 18 - 20; Vertebrae: 33 - 35. Several geographical variations. Adults almost black and some populations have a reddish tail.

Oviparous. Eggs are demersal and adhesive.
