Diagnosis

This species is distinguished from all its congeners by the following set of characters: body deep and becoming compressed and less deep with growth; D XII,10, the first 2 dorsal-fin spines rudimentary (2 dorsal-fin spines on first dorsal pterygiophore); the dorsal-fin with two morpho types of configuration (Type I 'rigid type', fragile] as a rigid tapering spine and Type II ['flexible type', comparatively robust] as a flexible tapering spine in Group A - Red Sea, Group B - Gulf of Aden and eastern coast of Africa, and Group C - Persian Gulf, only Type II, is seen in both Group D - Madagascar to Sri Lanka and Group E - Eastern Indian Ocean, each Group is allopatric and is likely to have similar genetic structure (not analyzed in Group D or E). Colouration: body uniform pink with belly and lower jaw silvery, head red; spinous dorsal fin pink or red, other fins pink or pale pink; with pink tinge around eye; upper jaw often pinkish; anterior and posterior margins of the upper cheek scales nearly parallel just below rear edge of eye; orbit diameter is clearly less than suborbital depth (Ref. 124569).
