Etymology: Iniistius: Latin, in = in + Greek, istion = sail; trivittatus: Named for the 3 blackish bars on the body. More on authors: Randall & Cornish.
Environment: milieu / climate zone / depth range / distribution range

Northwest Pacific: known only from Hong Kong and Taiwan.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 30.0 cm TL male/unsexed; (Ref. 48636)
soft rays: 12. Upper half of the body with 3 blackish bars; dorsal and anal fins and dorsal edge of caudal fin with pink margin; forehead with a median pale blue line. Dorsal fin incised between 2nd and 3rd spines; approximately 1/3 the length of the 2nd spine, the gap about 1.5 times larger than between 1st and 2nd or 3rd and 4th spines; dorsal spines 1st and 2nd longer than the longest dorsal soft rays. Cheek with a broad band of small scales from below eye to slightly below corner of the mouth; 2-3 scales dorsally on opercle.
Juveniles in coastal waters along reef edges on sand or rubble, or open patches on reef. Adults mainly in deep outer reef habitats where they occur in small loose group along sand ridges (Ref. 48636).
