"The molecular phylogeny of aplocheiloid killifishes
shows a pattern similar to that of cichlids (Murphy &
Collier, 1997). The Neotropical and African clades are
sisters to each other, together forming the sister group
of the Indian-Malagasy clade. Within the latter, the single
species occurring on the Seychelles (Pachypanchax
playfairii) is sister to the two Malagasy Pachypanchax
rather than to the Indian Aplocheilus." - (Vences 2004)
