Aplocheiloidei is a suborder of the order Cyprinodontiformes consisting of three families which are commonly known as killifishes.
Families

The three families within the suborder Aplocheiloidei are:[2][3]

Aplocheilidae Bleeker, 1859
Nothobranchiidae Garman, 1895
Rivulidae Myers, 1925

Proposed taxonomy

Some authorities have lumped the three families into a single family, Aplocheilidae, a well-established name, chosen for its stability in usage over time, and to avoid the impact of a new name at the family rank for a popular aquarium fish group.[3] Under this proposal, the Aplocheilidae includes three subfamilies: Aplocheilinae for the species from Asia, Madagascar and the Seychelles; Cynolebiinae (called Rivulidae above) for the species from the Americas; and Nothobranchiinae for the species from the African mainland.[4]
