Espinhos dorsais (total) : 1; Espinhos anais: 0. Diagnosis: gill slits not extending ventrally beyond pectoral-fin insertions; maxillary barbels longer than head, bearing externally short and tuberculate ramifications and a broad membrane extending along their basal part; outer mandibular barbels with simple, thick ramifications, branches of inner mandibular barbels tuberculate, sometimes subdivided; mandibular teeth short, numbering 59-66 (possibly up to 82); pectoral-fin spines very strongly denticulate on inner margin, but nearly smooth on outer margin; dorsal-fin spine denticulate on front margin and prolonged into a filament; humeral process deep, granulose and not keeled ventrally; adipose fin very well developed and contiguous to rayed dorsal fin; body deep; eyes large (Ref. 57223).
Coloration: general background greyish-brown, colour pattern inverted, the ventral areas being dark (Ref. 57223).
Body shape (shape guide): fusiform / normal.
Occurs in vegetated areas of the lake. Omnivore, feeds on plankton and detritus (Ref.13868). Oviparous (Ref. 205). Maximum total length 350mm (Ref. 57223).
