English Names

Hot Springs Grass Frog (Ptychadena filwoha [no longer recognized]: Largen and Spawls, 2010, Amph. Rept. Ethiopia Eritrea: 176).

Nile Grass Frog (Channing and Rödel, 2019, Field Guide Frogs & Other Amph. Afr.: 340). 

Distribution

Nile drainage of Egypt and Sudan into Ethiopia, thence south into eastern Dem. Rep. Congo, Uganda, Rwanda, Burundi, western and southern Kenya and Tanzania; records beyond this area are likely based on misidentifications or unnamed species: Botswana, Mozambique, Swaziland, and extreme eastern Rep. South Africa; presumably in the Caprivi Strip of Namibia, Zimbabwe, Zambia, as well as northern Somalia, Djibouti, and southern Eritrea. 

Comment

 Dehling and Sinsch, 2013, Zool. Anz., 253: 143–157, described and discussed vocalizations, external morphology (comparing Ptychadena anchietae, Ptychadena nilotica, and Ptychodena porosissima), molecular markers, and resurrected Ptychadena nilotica from the synonymy of Ptychadena mascareniensis, where it had been placed by by Peters, 1869, Reisen Ost-Afr. 1859–1865, 3: 17 (with Rana bibroni); Boulenger, 1879, Bull. Soc. Zool. France, 4: 92-94;Boulenger, 1882, Cat. Batr. Sal. Coll. Brit. Mus., Ed. 2: 52; and Guibé and Lamotte, 1957, Bull. Inst. Franç. Afr. Noire, Ser. A, 19: 978. Formerly noted as Ptychadena cf mascareniensis (Clade A) of Vences, Kosuch, Rödel, Channing, Glaw, and Böhme, 2004, J. Biogeograph., 31: 593–601, who noted another unnamed species in Kenya which they labeled as Ptychadena cf mascareniensis (Clade D). Zimkus, Lawson, Barej, Barratt, Channing, Dash, Dehling, Du Preez, Gehring, Greenbaum, Gvoždík, Harvey, Kielgast, Kusamba, Nagy, Pabijan, Penner, Rödel, Vences, and Lötters, 2016, Mol. Phylogenet. Evol., 106: 254–269, recognized this species as a member of the Ptychadena mascareniensis complex and reported on molecular systematics and range.  Largen and Spawls, 2010, Amph. Rept. Ethiopia Eritrea: 176, provided a brief account for Ptychadena filwoha, and Largen, 2001, Tropical Zool., 14: 337, commented on the range of Ptychadena filwoha.  Phaka, Netherlands, Kruger, and Du Preez, 2017, Bilingual Field Guide Frogs Zululand: 56, provided a photograph, Zululand regional map, and a brief account of life history and identification. See detailed account for Egypt by Escoriza and Ben Hassine, 2019, Amph. N. Afr.: 266–269. Spawls, Wasonga, and Drewes, 2019, Amph. Kenya: 40, provided a photograph, range map, and brief characterization. Channing and Rödel, 2019, Field Guide Frogs & Other Amph. Afr.: 340–341, provided a brief account, photograph, and range map.
