Etymology: Henonemus: Greek, enioi, -ai, -a = sometimes, some + Greek, nema = filament (Ref. 45335); triacanthopomus: Name from the Greek 'tri' (three), 'acanthos' (spine), and 'poma' (opercle) referring to the maximum number of odontodes found in both opercles of the adult individuals, apparently a unique character among the species of the genus..

Short description Identification keys | Morphology | Morphometrics

Diagnosis: Differs from its congeners by having three or asymmetrically 4 opercular odontodes in specimens longer than 8 cm SL; a blackish ventral lobe of caudal fin; a row of mid-lateral dark blotches above the lateral line deflected dorsally on caudal peduncle; five interopercular odontodes inserted in the main series; and, lower jaw teeth arranged in seven rows (Ref. 57442).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00380 (0.00146 - 0.00990), b=3.08 (2.86 - 3.30), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.6 ±0.8 se; based on size and trophs of closest relatives

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