English Names

Two-colored Reed Frog (Frank and Ramus, 1995, Compl. Guide Scient. Common Names Amph. Rept. World: 66).


Known only from the type locality (Farenda Bango, Loanda, Angola).


Probably a synonym of Hyperolius marmoratus insignis Bocage, 1867 (Laurent, 1985, In Frost (ed.), Amph. Species World: 208). Junior secondary homonym of Hyperolius bicolor (Gray, 1842) (= Litoria bicolor).Because the only specimen, the holotype, is lost the taxonomic status will be difficult to assess according to Marques, Ceríaco, Blackburn, and Bauer, 2018, Proc. California Acad. Sci., Ser. 4, 65 (Suppl. II): 96, who provided a map for Angola and a brief account.
