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]
There are currently four recognized species in this genus:[2]
- Campellolebias brucei Vaz Ferreira & Sierra de Soriano, 1974 (Swordfin killifish)
- 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
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]
