Comment

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. Channing and Rödel, 2019, Field Guide Frogs & Other Amph. Afr.: 396, regarded this nominal taxon as too insufficiently known to treat adequately in their field guide. Not addressed by Portik, Bell, Blackburn, Bauer, Barratt, Branch, Burger, Channing, Colston, Conradie, Dehling, Drewes, Ernst, Greenbaum, Gvoždík, Harvey, Hillers, Hirschfeld, Jongsma, Kielgast, Kouete, Lawson, Leaché, Loader, Lötters, van der Meijden, Menegon, Müller, Nagy, Ofori-Boateng, Ohler, Papenfuss, Rößler, Sinsch, Rödel, Veith, Vindum, Zassi-Boulou, and McGuire, 2019, Syst. Biol., 68: 859–875.
