The following combination of characters can be useful to diagnose from other members of the complex: 7-10 grey bars on the flank in males; presence of bluish white dots on the anterior portion of the dorsal fin in males; caudal peduncle depth in males 13.2-15.4% SL; eye diameter in males 30.7-33.0% of head length; anal-fin base length in males 39.3-43.5% SL; head width in males 61.1-68.9% SL; ventral part of the flank bars in males straight and unconnected; and 2-3 dorsal-fin filaments reaching the posterior portion of the caudal fin, sometimes barely surpassing posterior caudal-fin margin (Ref. 89836).
