English Names

None noted.

Distribution

Savanna-forest ecotone regions of tropical West Africa from Senegal, Gambia, and Mali, to Dem. Rep. Congo; Central Republic of Congo, western and southeastern Democratic Republic of Congo, and western Nigeria,southern and western Democratic Republic of Congo. It is presumed to occur in the Cabinda Enclave of Angola, and probably also in northern Angola, Zambia and Malawi (see comment for discussion of West African populations).

Comment

See comment under Afrixalus quadrivittatus and Pickersgill, 2007, Afr. J. Herpetol., 56: 23-37. Largen and Spawls, 2010, Amph. Rept. Ethiopia Eritrea: 111, implied that the controversy may have to do with confusion with the very similar Afrixalus fulvovittatus and Afrixalus vittigerPickersgill, 2007, Afr. J. Herpetol., 56: 23-37, regarded Afrixalus "quadrivittatus" as a conglomeration of species not otherwise assignable to either Afrixalus fulvovittatus or Afrixalus vittiger. His treatment; by implication, of treating Hyperolius leptosomus Peters, 1877, and Hyperolius brevipalmatus Ahl, 1931, as not formally-recognized species, but as unapplied names, leaves the state of Afrixalus taxonomy in West Africa unsettled, a reflection on the real state of understanding of this difficult taxon. For this reason this record will sort in geographic searches to West Africa. This is not to imply that Afrixalus quadrivittatus (sensu stricto) occurs there, but that the savanna-forest ecotone regions of West Africa are inhabited by frogs currently associated with delimited species that Pickersgill (2007) regarded collectively as Afrixalus "quadrivittatus"Jackson and Blackburn, 2007, Salamandra, 43: 149-164, provided a record for Nouabale-Ndoki National Park, Rep. Congo. Lötters, Wagner, Bwong, Schick, Malonza, Muchai, Wasonga, and Veith, 2007, Fieldguide Amph. Rept. Kakamega Forest: 28-29, provided an account for a Kenya population.Jongsma, Tobi, Dixon-MacCallum, Bamba-Kaya, Yoga, Mbega, Mve Beh, Emrich, and Blackburn, 2017, Amph. Rept. Conserv., 11 (1: e144): 10–12, provided records for southeastern Gabon and briefly discussed habitat and range.
