Etymology: Trimma: Greek, trimma, -atos = something crushed (Ref. 45335); halonevum: Name from 'halo nevus', a skin condition characterized by pale spots with a red centre, referring to the similar spots on the body of the new species (the name was given by Dr. Irving Klinghofer, a Toronto physician).

Dorsal spines (total): 6 - 7; Dorsal soft rays (total): 8 - 10; Anal spines: 1; Anal soft rays: 8. Distinguished by the following characters: reddish orange to yellow orange with small pale edged red spots widely scattered on head and body; longitudinal scale series 23-25; predorsal scales 6-10; absence of scales on cheek; upper opercle with 2-3 cycloid scales; depth of body about 3.3 in SL (Ref. 90102).
Body shape (shape guide): fusiform / normal; Cross section: oval.

Inhabits coastal reefs on mixed algae and coral to about 20 meters depth (Ref. 48637). Minimum depth from Ref. 58018.

Estimates based on models

Preferred temperature (Ref. 123201): 27.1 - 29, mean 28.1 °C (based on 396 cells).

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

Bayesian length-weight: a=0.01023 (0.00477 - 0.02194), b=3.01 (2.83 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

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