Etymology: Trimma: Greek, trimma, -atos = something crushed (Ref. 45335);  annosum: Named in allusion to the plain grey cheek of the species, which is perhaps reminiscent of that class of elderly hirsute human males sometimes referred to as 'greybeards' (Ref. 49832).  More on author: Winterbottom.

This species is distinguished by the following characters: a shallow concave bony interorbital about half pupil-diameter in width; predorsal is completely covered with ctenoid scales, no naked patches, a large scale above and between the end of the eyes above the posterior half of the pupil; cheek no scales; operculum often with a single large ctenoid scale dorsally, often followed by a smaller cycloid scale posteriorly; pectoral-fin base with 3 large vertically elongate cycloid scales; prepelvic area has 4-5 rows of cycloid scales, 1 enlarged scale between the bases of the pelvic spines; pectoral rays normally unbranched, rarely with up to 4 rays with a single branch; fifth pelvic-fin ray branched once dichotomously, rarely branched twice resulting in 3 terminal tips, 40-65% the length of the fourth; no trough or groove posterodorsal to the eye; second and third dorsal spines subequal in length, not elongated; colour of head bluish grey, cheek uniform in colour, in life a yellowish orange spot about the size of the pupil on the middle of the anterior part of the operculum, a similar sized spot dorsally and posteriorly on the operculum, a smaller yellowish orange spot behind eye; central on the pectoral base is an oval yellowish orange to reddish orange spot; body with moderate sized yellowish orange spots in 4 rows anteriorly converging to 3 on the caudal peduncle; body is fully scaled; without nape crest; dorsal and anal rays usually I,8 (Ref. 100726).
