Distribution

Southern Cameroon, east and south through Gabon to the lower Congo Basin and northern Angola, and the north-western Zambian highlands; expected in Equatorial Guinea and western Dem. Rep. Congo.

Comment

Removed from the synonymy of Hyperolius adspersus by Channing, Hillers, Lötters, Rödel, Schick, Conradie, Rödder, Mercurio, Wagner, Dehling, Du Preez, Kielgast, and Burger, 2013, Zootaxa, 3620: 319, where it had been placed by Laurent, 1961, Rev. Zool. Bot. Afr., 64: 92. Removed from the synonymy of Hyperolius nasutus by Amiet, 2005, Rev. Suisse Zool., 112: 274, where it had been placed as a subspecies by Laurent, 1957, Explor. Parc Natl. Upemba, Miss. G.F. de Witte, 42: 1-47; and Laurent, 1961, Rev. Zool. Bot. Afr., 64: 92. In the Hyperolius nasutus group of Amiet, 2005, Rev. Suisse Zool., 112: 271-310, who discussed this and other species of this group in Cameroon. Schiøtz, 2006, Alytes, 24: 68, provided some comments on confusion with Hyperolius nasutus. Schiøtz, 2006, Alytes, 24: 46, provided a record for central Dem. Rep. Congo and discussed the difficulty in application of the name. Pauwels and Rödel, 2007, Herpetozoa, Wien, 19: 135-148, did not register the species as occurring in Gabon. See account for Cameroon by Amiet, 2012, Rainettes Cameroun: 288-295. Marques, Ceríaco, Blackburn, and Bauer, 2018, Proc. California Acad. Sci., Ser. 4, 65 (Suppl. II): 102, commented on the species in Angola. See Bittencourt-Silva, 2019, Amph. Rept. Conserv., 13 (2: e181): 6, for comments on morphology and ecology in western Zambia. Channing and Rödel, 2019, Field Guide Frogs & Other Amph. Afr.: 176–177, provided a brief account, photograph, and range map. Sánchez-Vialas, Calvo-Revuelta, Castroviejo-Fisher, and De la Riva, 2020, Proc. California Acad. Sci., Ser. 4, 66: 146, considered the species to be a possible member of the Equatorial Guinea fauna. Ernst, Lautenschläger, Branquima, and Hölting, 2020, Zoosyst. Evol., 96: 254, noted the presence in Uigé Province, northwestern Angola.
