Remarks on taxonomic status:

In 1983 P. H. Greenwood transferred Cardiopharynx to Cyathopharynx and regarded the former a junior synonym of the latter, because of the heart-shaped lower pharyngeal bone they have in common. This feature can also found in cichlids from outside Lake Tanganyika as stated by Poll (1986), and therefore cannot be seen as a unique character uniting all species possessing it into a single genus.

Sturmbauer & Meyer´s molecular analyses (1993) showed that Cardiopharynx may form a subclade together with Cyathopharynx and Ophthalmotilapia in the Ophthalmotilapia-clade, which also consists of the genera Ectodus, Lestradea, Cunningtonia and Aulonocranus. This has been confirmed by a recent molecular work, which has also shown that Cardiopharynx schoutedeni either is the most ancestral branch in this subclade or form the sister group of Ophthalmotilapia boops and O. nasuta (Koblmüller et al. 2004).
