Abstract
Evidence from morphology is used to infer the phylogeny of the superframily Poecilioidea using other cyprinodontoid fishes as outgroups. The three equ ally most parsimonious trees resulting from the phylogenetic analysis suppo rt the monophyly of the families Anablepidae and Poeciliidae with respect t o each other, but the previous taxonomy within the Poeciliinae is not consi stent with the resultant phylogenetic trees. The Poeciliidae is recognized with three subfamilies: the Aplocheilichthyinae containing solely Aplocheil ichthys spilauchen, the Procatopodinae containing Fluviphylax (Fluviphylaci ni) and the African lamp-eyed killifishes (Procatopodini), and the Poccilii nae. The inferred hierarchical relationships of included suprageneric taxa are: ((Oxyzygonectinae, Anablepinae) (Aplocheilichthyinae ((Fluviphylacini, Procatopodini) (Alfarini (Priapellini (Gambusini (Heterandrini (Cnesterodo ntini (Girardini, Poeciliini))))))))). The tribe Alfarini is resurrected an d a new tribe, the Priapellini, is described. Tomeurus gracilis is not the most basal poeciliine, and facultative viviparity in Tomeurus is not a plei somorphic intermediate condition of viviparity retained from the common anc estor of poeciliines. Facultative viviparity in Tomeurus is the result of a n evolutionary loss of obligate viviparity. Tomeurus gracilis is recognized as a member of the tribe Cnesterodontini. Lamprichthys tanganicus and Micr opanchax pelagicus are not sister taxa, and the pelagic lacustrine habits o f these two species are inferred to have evolved independently. Based on th e principles of vicariance biogeography, the origin of the Poecilioidea is inferred to have occurred before the separation of Africa and South America .
