Diagnosis |
Depth of body 2.6-2.9 times in SL; head length 3.1-3.4 times in SL (Ref. 47113). Eye diameter 2.9-3.2 times in HL; interorbital width 3.4-4.1 times in HL; premaxillary pedicel 2.4-3.1 times in HL and depth of preorbital 5.6-7.0 in HL (Ref. 47113). Teeth in 2 to 3 rows in upper and 3 to 4 rows in lower jaw (Ref. 47113). Males mostly with unicuspid teeth in all rows; in females outer rows contain unequally bicuspid and inner rows contain unequally tricuspid teeth (Ref. 47113). Length of pectoral fin 2.8-3.7 times in SL (Ref. 47113). Caudal peduncle 5.4-7.6 times in SL; peduncle depth 1.0-1.5 times in its length (Ref. 47113). Scales: 34-35 scales in a longitudinal series (Ref. 47113). Without spots on the flanks (Ref. 47113). Geographical variation seems to be restricted to the color of the blaze on the male's head and dorsal fin (Ref. 47113). |
