Maturity: L m   ?   range ? - ? cm
Max length : 16.6 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; eye at most 23% of head length and 46% of snout length; post-orbital length at least 60% of snout length; maxillary barbels unbranched, longer than head, without tubercles and bordered by a distinct basal membrane; outer mandibular barbels with many thick and short ramifications; branches of inner mandibular barbels subdivided and tuberculate; mandibular teeth moderately developed, numbering 37-43 (37 in the holotype); denticulations of pectoral-fin spines weaker on outer than on inner margin; dorsal-fin spine smooth anteriorly; humeral process triangular and keeled ventrally; adipose fin well developed and close to rayed dorsal fin; branched dorsal-fin rays, as well as dorsal- and pectoral-fin spines prolonged into filaments; spots present on body and fins (Ref. 57223 ). Coloration: body more or less dark brownish, covered, as the head and adipose fin, with large, rounded, black spots; other fins with smaller black spots; membranes of maxillary barbels black (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=0.01622 (0.00870 - 0.03023), b=2.98 (2.82 - 3.14), in cm Total Length, based on LWR estimates for this species & Genus-body shape (Ref. 93245 ). Trophic Level (Ref. 69278 ):  2.9   ±0.4 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 vulnerability (21 of 100) . Price category (Ref. 80766 ):   Unknown .
