TYPE LOCALITY.— “Cap Saint Jean, Guinée espagnole”, Cabo San Juan, Río Muni, Equatorial Guinea .

DISTRIBUTION.— This species has the largest geographic range in the genus, occuring from Nigeria to Gabon, and throughout Central African Republic, Democratic Republic of Congo and Republic of Congo. Within Equatorial Guinea, it has been recorded from Río Muni only, in Cabo San Juan ( Boulenger 1903) and in Monte Alén National Park ( De la Riva 1994).
