soft rays: 8;
Vertebrae: 28 - 29. This species is distinguished by the following characters: first gill arch with 18-19 rakers; eye diameter is greater than width of suborbital bone; depth of caudal peduncle more than twice in its length; 28-29 vertebrae, of them trunk 12-13; haemal arch of first caudal vertebra no spurs; D III 15-16, A I 8, soft rays in ventral fin 7; the ventral fin begins beyond vertical of posterior margin of pectoral fin insertion; the anal fin begins beyond vertical of last ray of dorsal fin (Ref. 117111).
Gonadal maturity at stage III for males (5.05 cm SL) and stage IV for female (9.3 cm SL) (Ref. 117111).

Bayesian length-weight: a=0.01000 (0.00400 - 0.02500), b=3.04 (2.82 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.6 ±0.2 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153
