Hyperolius olivaceus Buchholz and Peters in Peters, 1876, Monatsber. Preuss. Akad. Wiss. Berlin, 1876: 120. Syntypes: ZMB 8829 (3 specimens) according to Bauer, Günther, and Klipfel, 1995, in Bauer et al. (eds.), Herpetol. Contr. W.C.H. Peters: 44; now renumbered ZMB 8829 and ZMB 53264–53265 (formerly part of ZMB 8829) according to Tillack, de Ruiter, and Rödel, 2021, Zoosyst. Evol., Berlin, 97: 431. Type locality: "Limbareni am Ogowe" = Lambaréné on the river Ogooué (or Ogowe), Moyen-Ogooué Province, Gabon.

Hyperolius fimbriolatus Buchholz and Peters in Peters, 1876, Monatsber. Preuss. Akad. Wiss. Berlin, 1876: 121. Syntypes: ZMB 8830 (2 specimens), according to Laurent, 1961, Rev. Zool. Bot. Afr., 64: 79; now numbered ZMB 8830 and ZMB 65178 (formerly part of ZMB 8830) according to Tillack, de Ruiter, and Rödel, 2021, Zoosyst. Evol., Berlin, 97: 421. Type locality: "Limbareni am Ogowe" = Lambarene, Moyen-Ogooué Province, Gabon. Synonymy with Hyperolius cinnamomeoventris olivaceus suggested by Laurent, 1961, Rev. Zool. Bot. Afr., 64: 79, and confirmed by Lötters, Gossmann, Obame, and Böhme, 2001, Herpetofauna, Weinstadt, 23: 29.

Rappia fimbriolata — Boettger, 1888, Ber. Senckenb. Naturforsch. Ges., 1888: 98.

Hyperolius fimbriata — Tornier, 1896, in Möbius (ed.), Deutsch Ost-Afr., 3: 153. Incorrect subsequent spelling of Hyperolius fimbriolatus according to Tillack, de Ruiter, and Rödel, 2021, Zoosyst. Evol., Berlin, 97: 421–422.

Comment

Resurrected from the synonymy of Hyperolius cinnamomeoventris by Schick, Kielgast, Rödder, Muchai, Burger, and Lötters, 2010, Zootaxa, 2501: 33, but subsequently treated as a subspecies of Hyperolius cinnamomeoventris by Bell, Parra, Badjedjea, Barej, Blackburn, Burger, Channing, Dehling, Greenbaum, Gvoždík, Kielgast, Kasumba, Lötters, McLaughlin, Nagy, Rödel, Portik, Stuart, VanDerWal, Zassi-Boulou, and Zamudio, 2017, Mol. Ecol., 26: 5223–5244, who also discussed biogeography. Previously considered a junior synonym of Hyperolius fuscigula by Boulenger, 1882, Cat. Batr. Sal. Coll. Brit. Mus., Ed. 2: 124. Recognized by Ahl, 1931, Das Tierreich, 55: 293. Synonymy by Laurent, 1943, Ann. Mus. R. Congo Belge, Tervuren, Zool., 4: 67, 80. Synonymy considered tentative by Lötters, Gossmann, Obame, and Böhme, 2001, Herpetofauna, Weinstadt, 23: 28-29. Gilbert and Bell, 2017 "2018", Biol. J. Linn. Soc., 123: 1–11, reported on advertisement call. Jongsma, Tobi, Dixon-MacCallum, Bamba-Kaya, Yoga, Mbega, Mve Beh, Emrich, and Blackburn, 2017, Amph. Rept. Conserv., 11 (1: e144): 12–13, provided records for southeastern Gabon and briefly discussed habitat and range. Dewynter and Frétey, 2019, Cah. Fondation Biotope, 27: 24,, summarized the literature for Gabon, provided a photograph (p. 59). and recognized Hyperolius olivaceus. Channing and Rödel, 2019, Field Guide Frogs & Other Amph. Afr.: 196–197, provided a brief account, photograph, and range map. See brief account, range map, and photographs for Equatorial Guinea in Sánchez-Vialas, Calvo-Revuelta, Castroviejo-Fisher, and De la Riva, 2020, Proc. California Acad. Sci., Ser. 4, 66: 137–230. Tillack, de Ruiter, and Rödel, 2021, Zoosyst. Evol., Berlin, 97: 407–450, briefly discussed the types, collectors, collecting itinerary, and early literature for Hyperolius fimbriolatus and Hyperolius olivaceus.
