ZMB 65177 is the renumbered second syntype according to Tillack, de Ruiter, and Rödel, 2021, Zoosyst.

Syst., 93: 408; neotype designation invalidated by Perret, 1975, Rev. Suisse Zool., 82: 191. Type locality: "Cameruns"; restricted to Ngam, Cameroon, by Perret, 1966, Zool. Jahrb., Jena, Abt. Syst., 93: 408; restriction rejected by Perret, 1975, Rev. Suisse Zool., 82: 191. Type locality discussed and corrected to "Douala", Cameroon, by Frétey, Dubois, and Ohler, 2014, Alytes, 30: 11–28, and "Douala, Region Littoral, Cameroon" by Tillack, de Ruiter, and Rödel, 2021, Zoosyst.

Comment

See comments under Hyperolius mosaicus and Hyperolius endjami. See statement of geographic range, habitat, and conservation status in Stuart, Hoffmann, Chanson, Cox, Berridge, Ramani, and Young, 2008, Threatened Amph. World: 617. Schiøtz, 1999, Treefrogs Afr.: 137, provided a brief account and map. See account by Amiet, 2012, Rainettes Cameroun: 214–218. Channing, Rödel, and Channing, 2012, Tadpoles of Africa: 205–206, reported on comparative tadpole morphology. Dehling and Sinsch, 2019, Zool. Anz., 280: 65–77, considered this to be in the Hyperolius nasutus group. Channing and Rödel, 2019, Field Guide Frogs & Other Amph. Afr.: 196–197, provided a brief account, photograph, and range map. See Hyperolius ghesquieri. Not addressed by Portik, Bell, Blackburn, Bauer, Barratt, Branch, Burger, Channing, Colston, Conradie, Dehling, Drewes, Ernst, Greenbaum, Gvoždík, Harvey, Hillers, Hirschfeld, Jongsma, Kielgast, Kouete, Lawson, Leaché, Loader, Lötters, van der Meijden, Menegon, Müller, Nagy, Ofori-Boateng, Ohler, Papenfuss, Rößler, Sinsch, Rödel, Veith, Vindum, Zassi-Boulou, and McGuire, 2019, Syst.
