Biology
Dorsal spines (total): 10; Dorsal soft rays (total): 9; Anal spines: 3; Anal soft rays: 7. Suborbital spine absent. Preopercle with 3 transverse scale rows. Pectoral and pelvic fins not reaching to level of origin of anal fin. Upper lobe of caudal fin produced into a long trailing filament. First dorsal spine short. A line drawn upwards from posterior edge of the suborbital reaching the dorsal profile at or behind origin of dorsal fin. Axillary scale present. Color: upper part of body red, shading through rose-pink on the sides to pearly-white on the ventral surface.
