| Diagnosis |
Diagnosed from its congeners by the absence of the basal process of first gonactinost. Can be differentiated from its congeners by the sexual dimorphism on number of dorsal-fin rays, males with eight rays (very exceptionally seven) and females with seven rays (very exceptionally eight) (Ref. 76852). Description: Pectoral fin with 6-8 branched rays; longitudinal series of scales 27-29; transverse series of scales 7 (Ref. 76852). |
