From Parenti 1981:

REMARKS: Fundulopanchax contains species previously assigned to Aphyosemion that are more closely related to Nothobranchius than to the more primitive species of Aphyosemion. This usage of the genus Fundulopanchax differs from that of Loiselle and Glasgow (1971) who limited the group to large forms such as sjoestedti. The designation of a type species for the genus Callopanchax as A. occidentale by the International Commission places the genus Roloffia as an objective synonym of Callopanchax.

This decision has been rejected by many aquarists who believe that Myers (1924b) had either sjoestedti or another species in hand when he named the subgenus Callopanchax, with sjoestedti as the type, even though giving a description of occidentale. It is interesting to note that the sole lot catalogued as sjoestedti in the collection of the AMNH is an aquarium lot of occidentale.

Therefore, it is likely that Myers had specimens of occidentale not sjoestedti in hand when naming Callopanchax.

Originally thought to be a distinct species because of it's different coloration subsequent investigation revealed it's merely a color morph of OCC. It's not unusual in killies to have a 'red' and 'blue' form and OCC proves to be no exception - not unusual when you think that monroviae, one of a small number of species in Callopanchax does as well.



Another of the Huwaldi phenotypes.
