Rana Nutti Boulenger, 1896, Ann. Mag. Nat. Hist., Ser. 6, 18: 467. Syntypes: BMNH (2 specimens), by original designation; BMNH 1947.22.13 noted as a syntype by Pickersgill, 2007, Frog Search: 77. Channing, Dehling, Lötters, and Ernst, 2016, Zootaxa, 4155: 37, noted that two specimens are associated with this number. BMNH 1947.2.2.12-13 (originally 1896.5.14.27-28) are syntypes according to museum records. Type locality: "Lake Tanganyika".

Rana aberdariensis Angel, 1925, Voy. Alluaud et Jeannel Afr. Orient., 1: 42. Syntypes: MNHNP (17 specimens), including 1924. 3-9, according to Guibé, 1950 "1948", Cat. Types Amph. Mus. Natl. Hist.

Zool., 50: 194, and Channing, Dehling, Lötters, and Ernst, 2016, Zootaxa, 4155: 38. Removed from synonymy of Rana nutti by Loveridge, 1929, Bull. U.S. Natl. Mus., 151: 97. Synonymy with Rana wittei by Loveridge, 1936, Bull. Mus. Comp. Zool., 79: 372.

Rana (Rana) aberdariensis — De Witte, 1930, Rev. Zool. Bot. Afr., 19: 258, 261. Based on specimens of Rana fuscigula nutti according to De Witte, 1941, Explor. Parc Natl. Albert, Miss. G.F. de Witte (1933–1935), 33: 41.

Rana (Rana) nutti — Procter, 1920, Proc. Zool. Soc. London, 1920: 412.

Rana fuscigula nutti — De Witte, 1941, Explor. Parc Natl. Albert, Miss. G.F. de Witte (1933–1935), 33: 46.

Rana lubrica Pickersgill, 2007, Frog Search: 75. Holotype: ZMB 66246, by original designation. Type locality: "Bushara Island, Lake Bunyonyi, Uganda". Synonymy by Channing, Dehling, Lötters, and Ernst, 2016, Zootaxa, 4155:

Amietia lubrica — Frost, 2007, Amph. Spec. World, vers. 5.1. Assigned by implication of evidence provided in original publication: Larson, Castro, Behangana, and Greenbaum, 2016, Mol. Phylogenet. Evol., 99: 168–181.

Comment

Removed from the synonymy of Amietia angolensis by Channing, Dehling, Lötters, and Ernst, 2016, Zootaxa, 4155: 37–40 (who provided an account), where it had been placed by De Witte, 1930, Rev. Zool. Bot. Afr., 19: 261; Loveridge, 1933, Bull. Mus. Comp. Zool., 74: 363. (This synonymy disputed by Parker, 1931 "1930", Proc. Zool. Soc. London, 1930: 897.) See comment under Amietia angolensis for access to older literature that may address this species under the older umbrella name. Manthey, Reyes-Velasco, Freilich, and Boissinot, 2017, Biol. J. Linn. Soc., 122: 801–813, reported on molecular phylogeography in the Ethiopian Highlands. Spawls, Wasonga, and Drewes, 2019, Amph. Kenya: 32, provided a range map for Kenya, photograph, and brief characterization. Channing and Rödel, 2019, Field Guide Frogs & Other Amph. Afr.: 356–357, provided a brief account, photograph, and range map. Dehling and Sinsch, 2023, Diversity, 15 (512): 1–81, discussed the range, identification, natural history, advertisement call, and conservation status in Rwanda. Behangana, Byaruhanga, Magala, Katumba, Kagurusi, Dendi, and Luiselli, 2023, Wetlands, 43(88): 1–13, reported, as Amietia rubrica, on presence in the wetlands of southwestern Uganda. Spawls, Mazuch, and Mohammad, 2023, Handb. Amph. Rept. NE Afr.: 117–118, provided an account addressing identification, natural history, conservation status, and range, including a polygon map for northeastern Africa.
