This species’ currently accepted range stretches from eastern Nigeria (Mbam River) across central Cameroon (via the Sanaga River system of which the Mbam is a tributary) and across the border into Central African Republic (upper Mambéré basin).

It was described from ‘Jade Plateau, Cameroon’, this apparently corresponding to the Lebo River which lies in what is now the Central African Republic and presumably forms part of the Mambéré headwaters.
