It belongs to the subgenus Chromaphyosemion Radda, 1971 and is distinguished from its relatives by a unique/diagnostic combination of characters: orange unpaired fins, an anal fin without spots, an orange throat and purple to blue-grey flanks. The new species is also genetically differentiated from all the other Chromaphyosemion species as revealed by mtDNA (cytochrome b) analysis and characterised by a unique karyotype showing tentative sex chromosomes with 2n=35 chromosomes in males versus 2n=36 in females. 2013 text https://www.documentation.ird.fr/hor/fdi:010059890 fdi:010059890 Agnèse Jean-François, Legros O., Cazaux B., Estivals G..
