Diagnosis |
Diagnosis: gill slits not extending ventrally beyond pectoral-fin insertions; interorbital space over 50% of head width; post-orbital length at least 60% of snout length; maxillary barbels longer than head, unbranched, without tubercles and bordered by a short but distinct, dark basal membrane; outer mandibular barbels with rather numerous, simple ramifications, branches of inner mandibular barbels subdivided, thick and tuberculate; mandibular teeth rather short, numbering 36-48; denticulations of pectoral-fin spines strong on inner, and hardly visible on outer margin; dorsal-fin spine smooth anteriorly, except for some apical denticles; first branched ray of dorsal and pectoral fins prolonged into a filament; adipose fin high and long, distincly separated from rayed dorsal fin; humeral process deep, pointed and granulose, not keeled ventrally; body covered with very small black specks; caudal fin without spots or dots (Ref. 57223). Coloration: uniformly brownish, with numerous very small black spots, also on adipose fin, but none on other fins (Ref. 57223). |
