Max length : 22.9 cm SL male/unsexed; (Ref. 57223 )

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 broadly fringed, shorter than head, unbranched and without tubercles, but with a broad, dark brown basal membrane; outer mandibular barbels with few, short and thick ramifications; branches of inner mandibular barbels more numerous, short, subdivided and tuberculate; width of premaxillary tooth plate comprised at least twice in eye diameter; mandibular teeth rather short, numbering 19-37 (29 in the holotype); dorsal-fin spine smooth on anterior margin; humeral process small and triangular, not distinctly keeled, but nevertheless swollen ventrally; adipose fin rather long, but very low and distinctly separated from rayed dorsal fin; coloration very dark, caudal fin lobes not black edged (Ref. 57223 ). Coloration: body more or less uniformly blackish on back and sides, ventral areas light; fins dark brown (Ref. 57223 ).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805 ):  PD 50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245 ). Trophic Level (Ref. 69278 ):  2.9   ±0.3 se; Based on size and trophs of closest relatives Resilience (Ref. 69278 ):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.). Vulnerability (Ref. 59153 ):  Low to moderate vulnerability (28 of 100) . Price category (Ref. 80766 ):   Unknown .
