Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 10 - 11; Anal soft rays: 10 - 11. Distinguished from all other Hemiodus species, except H. ternetzi and H. thayeria, by the presence of a dark longitudinal stripe extending from behind the eye or the opercle to the tip of the lower caudal fin lobe. This species is distinguished from H. ternetzi and H. thayeria by the possession of a dorsal fin oblique blotch, extending from its anterior distal portion through the middle basal portion of the fin.

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=0.01148 (0.00363 - 0.03629), b=2.93 (2.68 - 3.18), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  2.7   ±0.3 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
