Duri punggung (Keseluruhan (total)): 1; duri punggung lunak (Keseluruhan (total)): 7; Duri dubur 0; Sirip dubur lunak: 13. Diagnosis: gill slits not extending ventrally beyond pectoral-fin insertions; snout pointed, over 65% of head length; 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 distinct basal membrane; outer mandibular barbels with simple ramifications; branches of inner mandibular barbels subdivided; mandibular teeth rather long, numbering 30; dorsal-fin spine smooth anteriorly; denticulation on pectoral-fin spines rather fine; humeral process triangular, pointed and not keeled ventrally; adipose fin small and very far from rayed dorsal fin (Ref. 57223).
Coloration: skin of the only preserved and known (stuffed) specimen brownish, with numerous small black spots on sides and adipose fin (Ref. 57223).
Maximum TL was recorded at 70.0 cm (Ref. 7362, 57223). Oviparous (Ref. 205).

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=0.01549 (0.00700 - 0.03427), b=2.88 (2.70 - 3.06), 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
Daya lenting (Ref.
120179): sedang, Waktu penggandaan populasi minimum 1.4 - 4.4 tahun (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Moderate to high vulnerability (49 of 100).
