簡短描述 型態特徵 | 形態測量圖

背棘 (總數): 7; 背的軟條 (總數): 8; 臀棘 1; 臀鰭軟條: 6 - 8. This species is distinguished by the following characters: scales on cheeks and opercle; scales in predorsal midline 8-10; unbranched pectoral fin rays 17-18; unbranched 5th pelvic fin ray 40-47% length of 4th ray; total gill rakers 21-22; broad interorbital (56-79% pupil width) with narrow crease-like postorbital groove, ending at posteriormost papilla in row p; papillae in row p 8, with 2 papillae ventral to papilla row n; nasal apparatus small and situated on anterior one-third of snout with posterior nares forming posterodorsal margin of nasal sac; colour when alive or freshly collected has the dorsal surface of eye light blue; preserved specimens with melanophores on dorsal surface of snout and mostly adjacent to nasal capsules (Ref. 118315).

Differs from Trimma blematium by having 17-18 pectoral fin rays (vs. 16), unbranched 5th pelvic fin ray (vs. branched), with 8 papillae in row 'p' (vs. 7 papillae); and in live specimens, the blue colour over the top of the eyes is less darker in this species than in T. blematium (Ref. 118315).

生物學特性     字彙 (例如 epibenthic)

Observed and collected from a nearshore reef which almost has no exposure to waves or currents, on a silty sand and rubble slope (Ref. 118315).
