TYPE LOCALITY.— “ Efulen ”, Cameroon , and “Cape St. John and the Rio Benito District” (Cabo San Juan and Benito River, Equatorial Guinea) .

DISTRIBUTION.— Leptopelis calcaratus inhabits the rainforests of the Gulf of Guinea region, from southeastern Nigeria to Gabon and eastern Democratic Republic of Congo. In Equatorial Guinea, it is present on Bioko (Mertens 1965; Hydeman et al. 2017) and Río Muni (Boulenger 1906a; De la Riva 1994) (Map 8B).

COMMENTS.— Populations from Bioko represent an independent lineage from those from mainland Cameroon (authors’ unpublished data). However, an integrative approach is necessary to test if this insular lineage is part of the geographically structured intraspecific variability or a distinctive species.
