Description
Dorsal spines (total): 7; Dorsal soft rays (total): 8-10; Anal spines: 1; Anal soft rays: 8; Pectoral-fin rays: 18. Presence of a deep trough in the bony interorbital region about half pupil-diameter in width; With a shallow trough behind the eye along the upper half of the posterodorsal margin of the eye; Naked predorsal midline, sides of nape is scaled to just behind the eye; No scales on cheek and opercle; The pelvic fins is connected by a basal membrane reaching to the tips of fifth ray, forming an indented plate; Central 4-11 pectoral rays are branched; 5-6 light stripes (orange to red in life) on head and with dark blue interspaces, the body light with distinct scattered oval or round spots (yellowish-orange, orange or reddish in life); The snout is mostly darkly pigmented without distinct stripes in preserved material, but with orange stripes in life; The upper lip largely dark, except posteriorly, usually with orange stripes from the eye obscured by dark pigment on the jaws; Uniformly dark lower lip; Lower surface of the head with a black curved stripe and with a median black bar connecting to the lower lip; Branchiostegal membranes are predominantly light, except for the stripe and the inner margin of the membranes. Max. length: 2.45 cm SL. Max. lifespan: 138 days. Depth range: 1 - 22 m.
Color
Head with narrow reddish orange stripes (depth about half of charcoal blue interspaces ventrally and about equal to interspaces dorsally); Dark interspace forming stripe on midline from first dorsal origin forward to posterior interorbital space or to just behind the posterior margin of interorbital trench, and not continuing as a distinct stripe between eyes or on snout (although there may be dark pigment in midline of the snout); Uppermost light stripe extending from dorsal margin of eye to below first dorsal origin; Second upper light stripe extending from posterodorsal margin of eye to below first dorsal fin; Third light stripe from just above middle of eye, arching along dorsal margin of preopercle and opercle, ending just above pectoral-fin base; Fourth stripe beginning along middle of upper lip arching upward and continuing along lower iris extending posteriorly onto upper pectoral base; Fifth stripe beginning at posterior tip of jaws, but usually interrupted by dark pigment on jaws, extending horizontally along cheek on to pectoral-fin base, just below middle; Lower surface of head with some orange pigment (not fully visible); A short stripe from anterodorsal margin of eye crossing upper lip, but not lower lip, sometimes obscured by dark pigment; Top of snout dark; Body with an overall charcoal grey coloration, varying from dark (similar to interspaces on head) to a lighter grey; Approximately 5 rows of round yellowish-orange, orange or reddish round and irregularly shaped oval spots; Spots spaced longitudinally by at least 1 scale row. Pectoral and pelvic fins largely translucent, often with a yellowish or orange tinge. First dorsal fin with a narrow yellow to orange stripe near base (much narrower than head stripes), basal part of fin grey to dusky, distal two thirds of fin translucent to faintly grey. Second dorsal fin with a narrow yellow to orange stripe basally, similar to stripe on first dorsal fin, sometimes stripe broken into a series of spots centered on fin rays; Above yellow or orange stripe a series of yellow or orange spots paralleling lower stripe anteriorly, but becoming irregular posteriorly; Remainder of fin dusky to grey, darker below lower yellow or orange stripe. Anal fin yellow to orange, with distal margin of fin pale grey to bluish-grey. Caudal fin with yellow to orange pigment concentrated along fin rays, with membranes grey.
Etymology
Trimma: from Greek, trimma, -atos = something crushed.
capostriatum: from the Latin, caput = a head, end or point + from Latin, striatus = striped in reference to the alternating red and charcoal-blue stripes on the head.
Original description: Zonogobius capostriata Goren, 1981 - Type locality: Canala Bay, New Caledonia.
Distribution
Western Pacific: Palau; New Britain (Papua New Guinea) and Queensland (Australia) east to Solomon Islands and Vanuatu; Possibly Fiji.
Biology
Common on middle and outer reefs. No morphological or color differences were noted between sexes.
Similar species
Trimma striatum (Herre, 1945) - Reported from Indo-West Pacific: Maldives east to Philippines. Trimma capostriatum has round or oval light spots (yellow to orange in life) in longitudinal rows on the body. Each spot is centred on a single scale, but separated by one or more scales from other spots. In Trimma striatum the body is uniformly colored. Frequently each scale has a thin, vertically elongate area lighter than the rest of the scale.
