Crumenifera pusilla Cope, 1862, Proc. Acad. Nat. Sci. Philadelphia, 14: 343. Type(s): Not designated; ANSP 11323 is holotype according to Malnate, 1971, Proc. Acad. Nat. Sci. Philadelphia, 123: 352. Type locality: "Umvoti", KwaZulu-Natal, Rep. South Africa. Given, apparently in error as "Umvoti, W. Africa" by Boulenger, 1882, Cat. Batr. Sal. Coll. Brit. Mus., Ed. 2: 127.

Hyperolius heuglini Steindachner, 1864, Verh. Zool. Bot. Ges. Wien, 14: 244. Type(s): NHMW 32923 tentatively listed as holotype by Tiedemann and Grillitsch, 2000 "1999", Herpetozoa, Wien, 12: 148. Type locality: Abyssinia [= Ethiopia]. Provisional synonymy with Hyperolius microps by Boulenger, 1882, Cat. Batr. Sal. Coll. Brit. Mus., Ed. 2: 127.

Rappia pusilla — Boulenger, 1882, Cat. Batr. Sal. Coll. Brit. Mus., Ed. 2: 127; Barbour, 1911, Bull. Mus. Comp. Zool., 54: 133.

Hyperolius pusillus — Noble, 1924, Bull. Am. Mus. Nat. Hist., 49: 251, 328; Loveridge, 1936, Bull. Mus. Comp. Zool., 79: 407; Loveridge, 1953, Q. J. Florida Acad. Sci., 16: 147.

Syntypes: MMK (2 specimens); BMNH records have 1947.2.11.29–39 (formerly 1934.10.8.8–10) as syntypes but this requires confirmation. Type locality: "Port St. Johns", Pondoland, Rep. South Africa. Synonymy by Loveridge, 1936, Bull. Mus. Comp. Zool., 79: 372; Loveridge, 1938, Proc. Biol. Soc. Washington, 51: 213–214; and Ohler and Frétey, 2014, J. E. Afr. Nat. Hist., 103: 87.

Comment

Poynton and Broadley, 1987, Ann. Natal Mus., 28: 205, noted that Zambian records are referable to Hyperolius viridis. See brief taxonomic discussion of Poynton, 1964, Ann. Natal Mus., 17: 191–192, and accounts by Schiøtz, 1999, Treefrogs Afr.: 185–186, Channing, 2001, Amph. Cent. S. Afr.: 176–177, Channing and Howell, 2006, Amph. E. Afr.: 178–179, Alexander, 2004, in Minter et al. (eds.), Atlas Frogs S. Afr. Lesotho and Swaziland: 146–147, Pickersgill, 2007, Frog Search: 346–349 (who implied a cryptic species exists in Malawi), and Du Preez and Carruthers, 2009, Compl. Guide Frogs S. Afr.: 262–263. Mercurio, 2011, Amph. Malawi: 183–185, provided an account for Malawi. Channing, Rödel, and Channing, 2012, Tadpoles of Africa: 220–221, discussed comparative larval morphology. Harper, Measey, Patrick, Menegon, and Vonesh, 2010, Field Guide Amph. E. Arc Mts. Tanzania and Kenya: 198–199, provided a brief account and photograph. Marques, Ceríaco, Blackburn, and Bauer, 2018, Proc. California Acad. Sci., Ser. 4, 65 (Suppl. II): 111–112, provided a map for Angola and a brief account, noting that the Angolan specimens needed to be reviewed and also implied that the records likely were misidentifications. Phaka, Netherlands, Kruger, and Du Preez, 2017, Bilingual Field Guide Frogs Zululand: 44, provided a photograph, Zululand regional map, and a brief account of life history and identification. Spawls, Wasonga, and Drewes, 2019, Amph. Kenya: 23, provided a range map for Kenya, photograph, and brief characterization. See Hyperolius albofrenatus which is a likely synonym.
