Remarks on taxonomic status:

The genus Ophthalmotilapia was originally described by Pellegrin in 1904, and several authors has since re-diagnosed the genera and the varying number of included species, e.g. Regan (1920), Poll & Matthes (1962), Greenwood (1983) and Poll (1986). Recently Hanssens et al. (1999) did a morphometric analysis of Ophthalmotilapia, and they found several inconsistencies in the hitherto published material on the genus, when compared with the type-series, and a new diagnosis of the genus and its species was designated (listed above).

Hanssens et al.’s analysis showed the existence of a population at Mtoto, D.R. Congo, that could not be designated to either O. ventralis or O. heterodonta, and interestingly this population differ clearly in coloration from both the northern O. heterodonta and southern O. ventralis populations. The taxonomic status of the Mtoto population is still uncertain.

The molecular analysis of the tribe Ectodini by Koblmüller et al. (2004) showed that Ophthalmotilapia form a subclade within the Ophthalmotilapia-clade, together with the genera Cardiopharynx and Cyathopharynx. The analysis could not support the monophyly of the genus Ophthalmotilapia, as O. heterodonta and O. ventralis formed a cluster together with Cyathopharynx furcifer (could actually be C. foae, a taxa not considered valid by all authors, neither in the publication by Koblmüller et al.), whereas Ophthalmotilapia nasuta and O. boops formed a sister species pair. Koblmüller et al. therefore suggest a revision of the genus Ophthalmotilapia.
