Remarks on taxonomic status:

The genus Callochromis has long been regarded as a phylogenetic entity and molecular analyses has confirmed that Callochromis is a monophyletic clade within the Ectodini tribe (Sturmbauer & Meyer 1993; Koblmüller et al. 2004).

The number of valid species within the genus has varied through time though; C. melanostigma has on more than one occasion been regarded as a subspecies of C. macrops and C. stappersii has on and off been regarded as a junior synonym of C. pleurospilus, latest by Takahashi & Nakaya in 1998. Molecular analyses have shown that C. stappersii may in fact be a valid taxa (Koblmüller et al. 2004) – a topic that will be addressed in a separate paper.
