soft rays: 39;
Vertebrae: 50. This species is distinguished from its congeners by the following set of characters: total vertebrae 50; D 47; A 39; pectoral-fin rays 32; principal caudal-fin rays 10; pectoral proximal radials 4 (first to third with notches); both jaws with trilobate teeth; gill slit 7.1 % SL, extending in front of 7th pectoral-fin ray base; maximum body depth is 19.1 % SL; disk length 7.9 % SL; the anus midway between posterior margin of pelvic disk and anal-fin origin. Colour of body and fins light orange, except for the blackish peritoneum (occipital region, operculum and anterior half of tail lacking epidermis; dorsal and anal fins partly lacking membranes) (Ref. 120239).
The gonad is pouch-like, translucent whitish, with ovarian eggs 0.35-0.75 [average ± standard deviation 0.50 ± 0.14 (n = 62)] mm in diameter (Ref. 120239)..

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= No PD50 data [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00427 (0.00194 - 0.00940), b=3.19 (3.01 - 3.37), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.2 ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (14 of 100) .
