" One of the objects of the present paper is to take a fresh look at the phylogenetic relationship of Hemichromis using information derived from more detailed anatomical studies, by extending the comparative basis to include not only more African taxa but also Madagascan and Neotropical species, and by using, in the final analysis of its relationships, only features which, as far as can be established, are derived ones. The results of this investigation are, in one respect, disappointing. On the positive side, Hemichromis can be shown to be a member of the African cichlid assemblage, and that amongst the assemblage it is not an entirely primitive taxon; indeed it possesses several unique derived features, and shares many other apomorphies with various African and Neotropical species. The disappointment stems from the fact that a presumed sister group for the genus can only be recognized on a synapomorphy that could be considered equivocal "
