Can be diagnosed by the combination of the following characters: origin of anal fin about ½ -1 ½ scales behind dorsal-fin base; anal fin with 13-15½ branched rays; gill rakers 21-25; lateral line scales 57-67+4; ventral keel exposed for 5-12 scales in front of anus; head length 21-24% SL; predorsal length 52-56% SL; caudal peduncle depth 1.9-2.4 times in its length; caudal peduncle length 19-22% SL; eye diameter 5.1-6.7% SL; 1.1-1.6 times in interorbital distance; 22-29% head length; few, large tubercles in nuptial males (Ref. 75107). Description: dorsal fin with 8½ branched rays; anal fin with 13 -15½ branched rays (Ref. 75107). |
