Etymology: Charax: Charax, -akos = a fish without identification (Ref. 45335); delimai: Named for Flávio César Thadeu de Lima for his great contributions to the knowledge of neotropical freshwater fishes and for collecting most of the specimens that served as the basis for the species description.
Eponymy: Dr Flávio César Thadeo de Lima (d: 1974) is a Brazilian zoologist and ichthyologist who is a specialist in the systematics of freshwater Neotropical fish of the order Characiformes. [...] (Ref. 128868), visit book page.

Descrição suscinta
Chaves de identificação | Morfologia | Morfometria
Raios dorsais (total) : 11; Vértebras: 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).
