"Panchax"

"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)
