簡短描述
型態特徵 | 形態測量圖
背的軟條 (總數): 11; 脊椎骨: 34 - 35. Charax delimai together with C. tectifer, C. metae and some specimens of C. gibbosus, C. rupununi and C. condei are the only members of the genus bearing teeth on the ectopterygoid. It can be distinguished from C. condei in having the lateral line complete (vs. incomplete); from C. gibbosus and C. rupununi in having anal-fin origin on vertical or slightly posterior to dorsal-fin origin (vs. anal-fin origin anterior to the vertical through the dorsal-fin origin); from C. tectifer in having (vs. absence) superficial neuromasts on body, with neuromasts dorso-ventrally arranged on trunk scales except those on the lateral line where neuromasts are absent; and from C. metae in having 3-15 ectopterygoid teeth (vs. 20-50), 10-12 transverse scale rows between the humeral spot and the supracleithrum (vs. 7-9) and the humeral spot distance 48-51% of SL (vs. 41.6-47% of SL) (Ref. 96861).
