Abstract

Chromaphyosemion ecucuense, new species, and C. erythron, new species, are described from the coastal plain of Equatorial Guinea. Both species are distinguished from their congeners by unique combinations of adult males colouration characters. They are closely related to C. kouamense, C. malumbresi and C. melanogaster according to mtDNA studies. Chromaphyosemion ecucuense was recently included in C. malumbresi as a second phenotype. This view is rejected here as both species can easily be diagnosed by colour pattern and are equally differentiated compared to other species in this genus.
