They are small fish, up to 5 cm (2.0 in) in total length.^[2] Uniquely among killifish, Campellolebias and the closely related Cynopoecilus have internal fertilization. A part of the males' anal fin forms a "pseudo-gonopodium" that is used for inseminating the female.^[1]

• Campellolebias chrysolineatus W. J. E. M. Costa, Lacerda & G. C. Brasil, 1989
• Campellolebias dorsimaculatus W. J. E. M. Costa, Lacerda & G. C. Brasil, 1989
• Campellolebias intermedius W. J. E. M. Costa & De Luca, 2006

Etymology

The generic name Campellolebias is a combination of Campello, which honours the Brazilian chemical engineer, aquarist and amateur ichthyologist Gilberto Campello Brasil (1945–2008) and lebias a Greek word for a small fish which was applied to Killifish by Georges Cuvier and is now used a root for names within the order Cyprinodontiformes. Vaz Ferreira & Sierra de Soriano described Campello Brasil as an "enthusiastic scholar" of Brazilian killifishes and he also collected specimens, sending them to the Vaz Ferreira & Sierra de Soriano.^[3]
