Hyperolius obstetricans (Ahl, 1931)

Class: Amphibia > Order: Anura > Family: Hyperoliidae > Subfamily: Hyperoliinae > Genus: Hyperolius > Species: Hyperolius obstetricans

Hyperolius obstetricans Ahl, 1931, Mitt. Zool. Mus. Berlin, 17: 90. Holotype: ZMB 77755 according to Tillack, de Ruiter, and Rödel, 2021, Zoosyst. Evol., Berlin, 97: 430, who reported it as found, although previously considered lost; MHNG 995.48 was designated neotype for the lost holotype by Perret, 1966, Zool. Jahrb., Jena, Abt. Syst., 93: 410. With the reappearance of the lost holotype the neotype designation is invalid. Type locality: "Bipindi, Kamerun [= Cameroon]"; invalid neotype from "Foulassi, rivière Lobô". The description in Ahl, 1931, Das Tierreich, 55: 364, appeared subsequent to the original according to Tillack, de Ruiter, and Rödel, 2021, Zoosyst. Evol., Berlin, 97: 407–450.

Comment

Lasso, Rial, Castroviejo, and De la Riva, 2002, Graellsia, 58: 21–34, provided notes on ecological distribution in Equatorial Guinea. See account for Cameroon by Amiet, 2012, Rainettes Cameroun: 124–136. Schiøtz, 1999, Treefrogs Afr.: 84–85, provided a brief account. Channing, Rödel, and Channing, 2012, Tadpoles of Africa: 196–197, reported on comparative tadpole morphology. Dewynter, Frétey, Jongsma, Bamba-Kaya, and Pauwels, 2018, Cah. Fondation Biotope, 18: 15, provided a brief account and photographs from the Monts Birougou area of Gabon. Dewynter and Frétey, 2019, Cah. Fondation Biotope, 27: 22, summarized the literature for Gabon and provided photographs (p. 56). Channing and Rödel, 2019, Field Guide Frogs & Other Amph. Afr.: 168–169, 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.  Dubois, Ohler, and Pyron, 2021, Megataxa, 5: 416, found Alexteroon obstetricans deeply imbedded within Hyperolius (as had Pyron and Wiens, 2011, Mol. Phylogenet. Evol., 61: 555. Tillack, de Ruiter, and Rödel, 2021, Zoosyst. Evol., Berlin, 97: 430–431, briefly discussed the types, their collector, and the itinerary of the collection. Ernst, Lautenschläger, Branquima, and Hölting, 2020, Zoosyst. Evol., 96: 253, noted the presence in the Serra da Canda, Zaire Province, northwestern Angola.
