Duri punggung (Keseluruhan (total)) : 0; duri punggung lunak (Keseluruhan (total)) : 82; Sirip dubur lunak: 62. Head short and oval-shaped dorsally; snout broadly rounded; eyes more laterally placed. Frontal fontanelle long and narrow; occipital fontanelle long and oval-shaped. Supraorbital and `dermosphenotic' bones separated, the latter somewhat reduced. Tooth plates broad. Pectoral spine straight; outer side with strong downward serrations. Gill rakers short and distantly set. Suprabranchial organ well developed. Openings of the secondary sensory canals display a regular pattern.

Facultative air-breathing (Ref. 126274); Nothing is known about the biology of this catfish (Ref. 78218).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00794 (0.00357 - 0.01766), b=2.96 (2.78 - 3.14), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.3 ±0.5 se; based on size and trophs of closest relatives

Daya lenting (Ref. 120179): Tinggi, Waktu penggandaan populasi minimum kurang dari 15 bulan (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
