Etymology: Trimma: Greek, trimma, -atos = something crushed (Ref. 45335); haimassum: Name from the Greek word 'haimasso' meaning stained with blood, referring to the blood-red spot above the posterior end of the opercle in live and fresh specimens. More on author: Winterbottom.

Morphology | Morphometrics
soft rays: 8 - 10. This species is characterized by having the following characters: a relatively deep body, numerous irregular scales with about 30 lateral rows and over 15 scales in the anterior transverse series, a fifth pelvic fin ray that branches twice dichotomously, usually a somewhat elongate second dorsal spine, no predorsal, cheek or opercular scales, a moderately wide bony interorbital with a fleshy median ridge between the eyes, and a dermal ridge anterior to the first dorsal spine. There is a red spot or elongate blotch above the opercle in live and fresh material, and the dorsal surface of the snout has a reticulated dark pattern, with dark transverse stripes over the dorsal margin of the orbit (Ref. 87358).
Inhabits caves and ledges on steep outer reef slopes (Ref. 90102).
