The systematic relationships of the freshwater teleost family Goodeidae inferred from a distance Wagner analysis of allozyme data are mainly consistent with previous systematic hypotheses, including some of those based on karyology. However, a recently proposed hypothesis based on bony anatomy of the mouth is not supported. Branching patterns of species within genera were 100% supported based on a jack knife consensus test except for Xenotoca , which is apparently a polyphyletic lineage. A fossil goodeid of Miocene age was used to calibrate the molecular clock for goodeids at Nei D = 1.0 = 11.3 million years.
