Kurzbeschreibung
Morphologie | Morphometrie
Rückenflossenstacheln (insgesamt): 1; Afterflossenstacheln 0. Diagnosis: gill slits not extending ventrally beyond pectoral-fin insertions; post-orbital length at least 60% of snout length; maxillary barbels longer than head, unbranched, without tubercles, but bordered by a narrow and very short basal membrane; outer mandibular barbels with long, simple and thin ramifications (6 in the lectotype); branches of inner mandibular barbels shorter, thicker, subdivided and tuberculate; mandibular teeth short and narrow, numbering 20-39 (39 in the lectotype); denticulations of pectoral-fin spines very weak on outer margins, much stronger on inner margin; dorsal-fin spine smooth anteriorly, except for a few apical denticles; humeral process narrow, triangular, pointed, at least twice as deep as long and not keeled ventrally; adipose fin not very high nor very long, and distinctly separated from rayed dorsal fin; body covered with irregular, more or less coalesced spots; belly dark (Ref. 57223).
Coloration: rather dark, with a network of more or less distinct light wavy bands; fins, in particular the caudal, with well visible spots aligned in bands (Ref. 57223).
Oviparous (Ref. 205). Maximum TL recorded was 10.5 cm (Ref. 57223).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 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): 2.9 ±0.4 se; based on size and trophs of closest relatives
Widerstandsfähigkeit (Ref.
120179): hoch, Verdopplung der Population dauert weniger als 15 Monate. (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
