Biogeographical realms

Leptopelis fiziensis was first described as a subspecies of Leptopelis modestus, based on specimens from the Fizi Territory in the eastern Democratic Republic of the Congo. Later on it has also been recorded in western Tanzania. However, recent molecular work suggests that its closest relative is Leptopelis karissimbensis rather than Leptopelis modestus. Moreover, some of the Tanzanian records might refer to another species.
