What is Molecular phylogeny and biogeography of the Malagasy and South Asian cichlids (Teleostei: Perciformes: Cichlidae) about?

Phylogenetic relationships of the Malagasy and South Asian cichlids are investigated using nucleotide characters from two mitochondrial genes, a 544 bp region of the large ribosomal subunit (16S) and a 649 bp region of cytochrome c oxidase subunit I (COI). This is the first molecular analysis to include a thorough taxonomic sampling of all Malagasy-South Asian genera, and a near complete taxonomic inventory of all valid species. Parsimony analysis of the combined data set (1193 aligned nucleotide positions) results in a single, completely resolved phylogenetic hypothesis. Results of this analysis, and that based on more comprehensive taxonomic sampling across Cichlidae for 16S alone (554 bp for 73 taxa), indicate that the Malagasy cichlids are paraphyletic, whereas the Malagasy and South Asian cichlids comprise a monophyletic group. In both analyses, the African and Neotropical assemblages are monophyletic. The Malagasy-South Asian cichlids are not recovered as plesiomorphic members of the family in either analysis. Two major clades are recovered within the Malagasy-South Asian assemblage and given subfamilial rank, Etroplinae, comprising Paretroplus (Madagascar) and Etroplus (sout
