| Observaciones | Males and females have meristic similarity but differ in head ventral surface color pattern. Males with dark cresentic marks or longitudinal pair of spots never found in females. Though both may have pale version of these markings or have uniformly dusky ventral surface of head. Also, females smaller, caudal-fin lobe never elongate, and dorsal-fin elements shorter than in males (Ref. 5296). |
