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, Chifundera, 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, and provided a dot map of genetically-confirmed records. 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. Du Preez and Carruthers, 2017, Frogs S. Afr., Compl. Guide: 336–337, provided an account, including a polygon range map for southern Africa, photograph, identification features, adult and larval morphology, habitat, and call. 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. Dehling, Mindje, and Sinsch, 2023, Salamandra, 59: 42–50, reported on the range in Rwanda, the morphological diagnosis, and call characteristics. 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 on presence in the wetlands of southwestern Uganda. Spawls, Mazuch, and Mohammad, 2023, Handb. Amph. Rept. NE Afr.: 101–102, provided an account addressing identification, natural history, conservation status, and range, including a dot map for northeastern Africa.
