Descrição suscinta
Morfologia | Morfometria
Espinhos dorsais (total): 1; Espinhos anais 0. Diagnosis: gill slits not extending ventrally beyond pectoral-fin insertions; eye not more than 20% of head length, and 26% of head width; in adults, post-orbital length at least 60% of snout length; maxillary barbels usually longer than head (except in young individuals), unbranched, without tubercles but with a broad, black basal membrane; outer mandibular barbels with rather long, tuberculate ramifications; branches of inner mandibular barbels shorter and strongly globose; mandibular teeth long, numbering 27-38 (33 in the holotype); dorsal-fin spine smooth anteriorly; denticulations of pectoral-fin spines finer on outer than on inner margin; humeral process not keeled ventrally, triangular, slender and pointed in young specimens, and deep, more strongly arched, and more blunt posteriorly in adults; dorsal- and pectoral-fin spines prolonged into a black filament; adipose fin not very well developed; head more flattened in young than in adults; outer margins of caudal-fin lobes black-edged; body covered with fine specks (Ref. 57223).
Coloration: body rather pale and covered with fine black specks and with larger spots in young individuals; rayed fins light and often spotless, but adipose fin always spotted; outer margins of caudal-fin lobes black-edged; broad black spot above humeral process (Ref. 57223).
Maximum TL was recorded at 28.1 cm (Ref. 7362, 57223). Oviparous (Ref. 205).
