Family:  Nemipteridae (Threadfin breams, Whiptail breams)
Max. size:  14 cm SL (male/unsexed)
Environment:  demersal; marine; depth range 30 - 100 m, non-migratory
Distribution:  Indo-West Pacific: Gulf of Thailand to southern Indonesia. This species has been confused with Nemipterus marginatus.
Diagnosis:  Dorsal spines (total): 10-10; Dorsal soft rays (total): 9-9; Anal spines: 3-3; Anal soft rays: 7-7. Lower edge of eye lies below a line drawn from tip of snout to upper base of pectoral fin. Lower edge of suborbital very slightly emarginate; the posterior edge more or less straight. Dorsal fin origin about 4-7 scale rows from an imaginary line projected upwards from posterior edge of suborbital to dorsal profile. Axillary scale present. Color: Oblique golden yellow stripe from beneath eye to middle of maxilla. Upper body pinkish, silvery white below. This species closely resembles N. marginatus, but lacks the filamentous extension to the upper lobe of the caudal fin; the posterior margin of the suborbital is more or less straight, rather than evenly curved; and the upper stripe on the body is not divided anteriorly.
