More Info

Distribution	Offshore reefs of north Western Australia, (Clerke Reef to Scott Reef), and the northern Great Barrier Reef, Queensland. Elsewhere the species occurs in the east-Indo-west Pacific. Inhabits sheltered reefs, forming groups among branches of Acropora corals in depths to bout 30 m.
Features	Dorsal fin VI + I, 9-10; Anal fin I, 8-9: Pectoral fin 16-17; Longitudinal scale series 23-24. Body depth 3.5-5.1 in SL; pectoral-fin rays simple; spinous dorsal elongate or filamentous in both sexes; genital papilla nonfimbriate; scales ctenoid except cycloid on breast, absent from head, nape and pectoral-fin base; pelvic fins separated, bases joins by thin membrane, fifth pelvic-fin ray well developed.
Remarks	In Australia, this species has previously been misidentified as Eviota nigriventris. Greenfield & Tornabene (2014) suggested that the identity of the Australian material was as genetic studies suggested that E. dorsogilva may be restricted to Fiji.
Etymology	The specific name dorsogilva is from dorso- (= back) and gilvus (= pale yellow) in reference to the colour of the body above the lateral line.
Species Citation	Eviota dorsogilva Greenfield & Randall, 2011, Zootaxa 2997: 56, figs 5–9, 11–15, 20. Type locality: north shore, reef east of Nananui-i-Cake reef, Viti Levu, Fiji (17.3334°S, 178°2729°E).
