背棘 (總數) : 1; 臀棘: 0. Diagnosis: mandibular barbels with few, divided ramifications, branches short and thickened, not tuberculate; maxillary barbel bordered with distinct, broad basal membrane, at least as broad as barbel; 22-27 movable mandibular teeth; dorsal spine with few serrations distally on anterior edge, but with several serrations along posterior edge and prolonged by a short filament; base of adipose fin 1.4-3.6 times distance between dorsal fin and base of adipose fin; body almost completely spotted, including belly and fins; interorbital distance at most 86.6% of snout length; postocular length at least 60% of snout length; entire margin of opercle smooth; caudal fin without single dark patch at base of each fin lobe (Ref. 81251).
Oviparous (Ref. 205). Maximum total length reported 26.2 cm (Ref. 3202).

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).
營養階層 (Ref.
69278): 2.9 ±0.3 se; based on size and trophs of closest relatives
回復力 (Ref.
120179): 高度, 族群倍增時間少於 15個月 (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
