Diagnosis

Diagnosis: lateral line complete or incomplete; 16-29 pored scales; 25-29 lateral line scales; 16-18 anal fin branched rays; 6/8 premaxillary teeth; 12-14 gill rakers on lower part of first branchial arch; caudal and adipose fins bright red; rayed dorsal fin carmin-red (Ref. 2880, 81279).

Description: anal fin with 3 unbranched and 16-18 branched rays; sexual dimorphism in anal fins of males; number of pored scales varies depending on individuals (Ref. 2880, 81279).

Coloration: silvery sides, silvery lateral stripe from gill cover to origin of caudal fin widening at the posterior end; rayed dorsal, adipose and caudal fins tinged with carmine red in both sexes; lateral band becomes black after preservation in formalin (Ref. 2880, 81279).
