Comment

 Auerbach, 1987, Amph. Rept. Botswana: 61, provided a summary account and grid map for Botswana. Schiøtz, 1999, Treefrogs Afr.: 97–100, provided an account for the species in the sense of including Hyperolius granulatus and Hyperolius benguellensis as synonyms. Channing, Moyer, and Burger, 2002, Afr. Zool., 37: 91–99, partitioned nominal Hyperolius nasutus into three cryptic species (Hyperolius nasutus, Hyperolius viridis, and Hyperolius acuticeps [now a synonym of Hyperolius microps]) on the basis of call-type and morphometrics. They retained Hyperolius benguellensis in the synonymy of Hyperolius nasutus. Schiøtz and Van Daele, 2003, Alytes, 20: 138–142, distinguished two species in this complex in Angola on the basis of call structure and color pattern, one of which they assigned the name Hyperolius benguellensis and the other to Hyperolius nasutus. Although their evidence clearly supports two taxa existing within nominal Hyperolius nasutus, it is not clear that the names are applied appropriately given that types were not examined and the possibility of unnamed members of this complex being involved did not seem to be addressed. Nago, Grell, Sinsin, and Rödel, 2006, Salamandra, 42: 93–108, provided a record of nominal Hyperolius nasutus for Benin. Discussed (as Hyperolius punctulatus) by Perret, 1976, Arq. Mus. Bocage, Ser. 2, 6: 27. Channing, Hillers, Lötters, Rödel, Schick, Conradie, Rödder, Mercurio, Wagner, Dehling, Du Preez, Kielgast, and Burger, 2013, Zootaxa, 3620: 334–335, provided an account. Harper, Measey, Patrick, Menegon, and Vonesh, 2010, Field Guide Amph. E. Arc Mts. Tanzania and Kenya: 174–175, provided a brief account of nominal Hyperolius nasutus, but inasmuch as the species is extralimital to the area of their guide it is unclear what species is being addressed. Ceríaco, Marques, and Bandeira, 2016, Anf. Rept. Parque Nac. Cangandala: 37, provided a brief account for Malanje Province, Angola. Du Preez and Carruthers, 2017, Frogs S. Afr., Compl. Guide: 274–275, provided an account, including a polygon range map, photograph, identification features, adult and larval morphology, habitat, and call. Marques, Ceríaco, Blackburn, and Bauer, 2018, Proc. California Acad. Sci., Ser. 4, 65 (Suppl. II): 106–108, provided a map for Angola and a brief account.  Butler, Ceríaco, Marques, Bandeira, Júlio, Heinicke, and Bauer, 2019, Herpetol. Rev., 50: 225–240, reported on a collection from Huila Province, southwestern Angola, as Hyperolius cf. nasutus. Channing and Rödel, 2019, Field Guide Frogs & Other Amph. Afr.: 176–177, provided a brief account, photograph, and range map. Mali, Banda, Chifundera, Badjedjea, Sebe, Lokasola, Ewango, Tungaluna, and Akaibe, 2019, Am. J. Zool., 2: 38–43, reported the species from the Okapi Wildlife Reserve, northeastern Dem. Rep. Congo, although the identification of this is now suspect. Conradie, Keates, Verburgt, Baptista, and Harvey, 2023, Amph. Rept. Conserv., 17: 33–34, provided an account and dot map of the species in Angola.
