Issue
According to Hopkins et al. (Ref. 81635) this species is a Lower Guinea endemic and should be placed in the genus Paramormyrops at species level, but they ignore the fact that there is also a subspecies in West Africa, Brienomyrus kingsleyae eburneensis, whose taxonomic status is now uncertain (Boden, pers. comm.).
