					Dorsal soft rays (total): 16 - 22; Anal soft rays: 16 - 22. Can be distinguished from all its congeners by the following combination of characters:  dorsal-fin origin in front of anal-fin origin, both dorsal fin and anal fin with 21 rays in males, 17-18 in females, and sides of body of males pale golden with transverse brownish-purple bars (Ref. 51692).
