Short description Morphology | Morphometrics

Dorsal spines (total): 1; Anal spines: 0. Diagnosis: gill slits not extending ventrally beyond pectoral-fin insertions; post-orbital length at most 60% of snout length; maxillary barbels not fringed or very slightly fringed at base, shorter than head, unbranched and without tubercles or basal membrane; mandibular barbels with thin, simple and rather long ramifications; mandibular teeth short and few, numbering 13-17 (17 in holotype); dorsal-fin spine short and smooth anteriorly; denticulation of pectoral-fin spines finer on outer than on inner margin; humeral process narrow, triangular, pointed and slightly keeled ventrally; adipose fin normally developed and well separated from rayed dorsal fin; head broad, eyes small, in dorso-lateral position; colour pattern of large rounded spots on body and fins (Ref. 57223). Coloration: yellow-olivaceous, darker on back, lighter on belly; back, sides, rayed dorsal fin and adipose fin covered with big black spots which become lighter on belly and smaller on other fins; head covered with numerous, very close-set black points smaller than those on body (Ref. 57223).

Maximum SL was recorded at 450mm, maximum TL at 550mm (Ref. 7362, 57223). Oviparous (Ref. 205).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01122 (0.00437 - 0.02882), b=2.97 (2.77 - 3.17), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.8 ±0.3 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (44 of 100).

Price category (Ref. 80766): Unknown.
