Dorsale stekels (totaal): 1; Anale stekels 0. Diagnosis: gill slits not extending ventrally beyond pectoral-fin insertions; post-orbital length at least 60% of snout length; maxillary barbels unbranched, longer than head, without tubercles and bordered by a black basal membrane; outer mandibular barbels with short and simple ramifications; branches of inner mandibular barbels subdivided/dichotomous but not tuberculate; mandibular teeth numbering 49-82 (64 in the lectotype); denticulations of pectoral-fin spines stronger on inner than on outer margin; dorsal-fin spine smooth anteriorly; only first branched dorsal-fin ray prolonged into a filament; humeral process triangular and granulose, deep, not keeled ventrally; adipose fin normally developed, truncate posteriorly and distinctly separated from rayed dorsal fin; eyes large (Ref. 57223). Coloration: body entirely brownish (including ventral areas); numerous small black spots, particularly on head, but sometimes also on sides and fins (Ref. 57223).

Maximum TL was recorded at 27.6 cm (Ref. 57223). Oviparous (Ref. 205).

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00933 (0.00303 - 0.02871), b=3.05 (2.80 - 3.30), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trofisch niveau (Ref. 69278): 2.5 ±0.31 se; based on food items.

Weerstandsvermogen (Ref. 120179): Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (17 of 100).

Prijsklasse (Ref. 80766): Unknown.
