背棘 (总数) : 1; 臀棘: 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 distinct narrow membrane basal half of their anterior margins; outer mandibular barbels with few, simple and rather short ramifications; branches of inner mandibular barbels more numerous, subdivided and globose; mandibular teeth strong and rather long, numbering 17-22; pectoral-fin spines finely denticulate, the serrations being stronger on inner than on outer margin; dorsal-fin spine anteriorly smooth; humeral process deep, triangular, granulose and not keeled ventrally; adipose fin very well developed and close to rayed dorsal fin (Ref. 57223).
Coloration: after preservation, the coloration becomes entirely light beige, with numerous small, dark specks (Ref. 57223). Live specimens: entirely yellow, with a dense pattern of black specks covering body and adipose fin; other, more widely spaced specks on fins (Ref. 57223).
Maximum SL was recorded at 34.5 cm (Ref. 7362, 57223), maximum TL at 480mm (Ref. 57223). Oviparous (Ref. 205).

Estimates based on models
Phylogenetic diversity index (Ref.

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01549 (0.00697 - 0.03443), b=2.90 (2.72 - 3.08), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
93245).
营养阶层 (Ref.
69278): 2.8 ±0.3 se; based on size and trophs of closest relatives
回复力 (Ref.
