Etymology: Scolopsis: Greek, skolex = worm + Greek, opsis = appearance (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; depth range ? - 35 m (Ref. 90102). Tropical; 19°N - 23°S, 115°E - 176°W
Western Pacific: Eastern Indonesia, Solomon Islands, Santa Cruz Islands and Fiji. This species closely resembles Scolopsis monogramma, and the two species have been previously confused.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 35.0 cm SL male/unsexed; (Ref. 48635); common length : 20.0 cm SL male/unsexed; (Ref. 3810)
soft rays: 7. Head scales reaching forward to or just behind level of anterior margin of eye. A small naked area on temporal region behind eye. Lower limb of preopercle scaly. Antrorse (forward-directed) suborbital spine absent. Pelvic fins long, reaching to or beyond level of anus. Upper lobe of caudal fin a little longer then lower lobe. Lobes produced to form filamentous extensions in larger specimens. Color: Upper body bluish, white below. Sides are also bluish. Scales on body with yellow centers forming horizontal lines above lateral line and diagonal lines below. A pinkish-brown stripe from behind eye, arching on back beneath lateral line and terminating behind tip of pectoral fin. Four blue stripes on head.
Inhabits coastal and lagoon waters, on sand rubble bottoms close to reefs. Usually seen solitary in 20+ m depth. May also be seen in groups. (Ref. 48635, 90102)
