Nemipteridae (Threadfin breams, Whiptail breams)
Etymology: Scolopsis: Name from the Greek masculine noun 'skolos' meaning 'thorn' and suffix '-opsis' (from Greek feminine n. 'opsis' meaning 'aspect', 'appearance') meaning ‘thorny appearance’ presumably referring to 'les dentelures de la préopercule, en ont aussi, et même d'épineuses, aux sous-orbitaires' mentioned by Cuvier (1814) in his designation of the genus. Name ending in -'opsis' are treated as feminine according to ICZN 1999: Article 30.1.2 (Ref. 130620).

Dorsal spines (total): 10; Dorsal soft rays (total): 9; Anal spines: 3; Anal soft rays: 7. Head scales reaching forward to between level of anterior margin of eyes and posterior nostrils. Lower limb of preopercle scaly. Antrorse (forward-directed) suborbital spine present beneath eye. Pelvic fins moderately long, reaching to or almost to level of anus. Color: Upper body greyish-brown, silvery-white below. A pearly-blue streak from behind eye along dorsal fin base. An oblique, brown-edged pearly-blue bar above the pectoral base. An elongate white blotch below lateral line on posterior half of body, a yellowish tinge above this blotch. Snout dusky and a black blotch on opercle.
