Comment

Vences, Kosuch, Rödel, Channing, Glaw, and Böhme, 2004, J. Biogeograph., 31: 593-601, suggested on the basis of mtDNA evidence that nominal Ptychadena mascareniensis is composed of a number of species, with Ptychadena mascareniensis sensu stricto restricted to Madagascar, the Seychelles, and the Mascarenes. Pickersgill, 2007, Frog Search: 134–135, recognized Ptychadena hylaea on the basis of Uganda material and on a rough sense of similarity with the description of this otherwise Liberian taxon. Given the disarray of the taxonomy of this group, it seems prudent to retain the taxon in this untilitarian "taxon". Although mtDNA has limited application to identifying lineages of organisms, Dehling and Sinsch, 2013, Zool. Anz., 253: 143-157, employed the same gene to delimit and resurrect the name Ptychadena nilotica for the major Nile River drainage (Clade A), which leaves a hodge-podge of unnamed or nomenclaturally unsorted populations from West, Southwest, and East Africa (e.g., Clade B from Cameroon and Benin; Clade C from Ivory Coast; and Clade Clade D from Kenya) and populations from Southwestern and South Africa that have not yet been sampled. Rather than continue to conflate Ptychadena mascareniensis with mainland populations or with Ptychadena nilotica, I just treat the remaining populations as Ptychadena "mascareniensis". This is highly unsatisfactory, but I do not want to submerge Ptychadena nilotica and Ptychadena mascareniensis into a larger taxon just because the revision of the group is incomplete (DRF, Oct. 2014). Padial, Crochet, Géniez, and Brito, 2013, Basic & Appl. Herpetol., 27: 11–22, discussed systematics, distribution, and conservation status in Mauritania, although more recent publications (e.g., Sampaio, Velo-Antón, Martínez-Freiría, Sánchez-Vialas, Pleguezuelos, Géniez, Crochet, and Brito, 2021, Conserv. Genetics, 22: 233–248) do not mention this complex so possibly these populations in Mauritania have been reidentified (DRF). Ohler and Frétey, 2014, J. E. Afr. Nat. Hist., 103: 91, provided a brief discussion of a collection from northern Mozambique. 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, further investigated the mainland group, including refining the concepts of Ptychadena nilotica and including Ptychadena newtoni within the Ptychadena mascareniensis complex. Non-Madagascan, unnamed lineages/species within this complex noted by  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, are (using their numbers for populations): 4: Ghana along the coast (presumably) to western Cameroon; 5: Mount Nimba highlands of Sierra Leone, Guinea, and Liberia; 6: equatorial region of Gabon, Rep. Congo, western Dem. Rep. Congo, east to northeastern Dem. Rep. Congo, Uganda, western Kenya; 7: southeastern Cameroon, exreme southwestern Cent. Afr. Rep., west-central Rep. Congo; 8: north-central Dem. Rep. Congo; 9: south-central Tanzania. Presumably these lineages will be appropriately named in the near future. Kassie Teme, 2016, J. Zool. Stud., 3(4): 1–6, reported a population from Warki (Kessa), northwestern Ethiopia. Sánchez-Vialas, Calvo-Revuelta, and Márquez, 2017, ZooKeys, 673: 125–133, discussed the species in Mauritania. M. Dehling and U. Sinsch in Spawls, Wasonga, and Drewes, 2019, Amph. Kenya: 40, suggested that most Kenya records of this nominal species are probably referable to Ptychadena nilotica.  Ernst, Lautenschläger, Branquima, and Hölting, 2020, Zoosyst. Evol., 96: 255, noted the presence in Uigé Province, northwestern Angola and suggested that records in southern Angola are referable to Ptychadena nilotica. Badjedjea, Masudi, Akaibe, and Gvoždík, 2022, Amph. Rept. Conserv., 16 (1: e301): 61–62, commented on a population of Ptychadena sp. aff. mascareniensis from the Kokolopori Bonobo Nature Reserve, Tshuapa Province, Dem. Rep. Congo. Discussion of range in Libya with dot map of distribution in that country (as Ptychadena sp., likely assignable to this complex) provided by Blackburn, Nielsen, and Jdeidi, 2022, Herpetol. Rev., 53: 211–219. Dehling and Sinsch, 2023, Diversity, 15 (512): 66, noted that populations assigned to this name from Rwanda have been reidentified as Ptychadena nilotica.  Gansa, Agadjihouèdé, and Hounkanrin, 2023, Afr. Zool., 58: 39–56, reported the species from the lower Ouémé Valley, southeastern Benin, and briefly descried habitat preference.

Accounts provided that apply to this complex were provided by Schmidt and Inger, 1959, Explor. Parc Natl. Upemba, Miss. G.F. de Witte, 56: 76-85, who described Ptychadena mascareniensis hylaea. Hylaea was subsequently considered a distinct species by Lamotte, 1967, Bull. Mus. Natl. Hist. Nat. Paris, Ser. 2, 39: 647-656, but Perret, 1979, Bull. Soc. Neuchatel. Sci. Nat., 102: 7-17, considered Ptychadena bibroni (Hallowell, 1845) to be a West African subspecies (following Boulenger, 1882, Cat. Batr. Sal. Coll. Brit. Mus., Ed. 2: 523) and hylaea to be a synonym of bibroni. See Poynton, 1964, Ann. Natal Mus., 17: 129, Poynton and Broadley, 1985, Ann. Natal Mus., 27: 148-149, and Lambiris, 1988, Lammergeyer, 39: 84. Perret, 1997, Bull. Soc. Neuchatel. Sci. Nat., 120: 77, discussed confusion in the literature between Ptychadena arnei and "Ptychadena bibroni". Passmore, 1977, S. Afr. J. Sci., 73: 212–214, described the advertisement call for a population in South Africa. See Largen, 1997, Tropical Zool., 10: 71, for comments on misidentified Ptychadena anchietae ascribed to this species and for discussion of distribution. Rödel, 2000, Herpetofauna W. Afr., 1: 128-132, discussed the issue of difficulty of identification of species related to Ptychadena mascareniensis and provided a comparison with Ptychadena bibroni, Ptychadena pujoli, Ptychadena mascareniensis hylaea, and Ptychadena arnei. Channing, 2001, Amph. Cent. S. Afr.: 329-331, and Du Preez and Carruthers, 2009, Compl. Guide Frogs S. Afr.: 312-313, provided accounts for the southern African populations. Largen, 2001, Tropical Zool., 14: 337-338, commented on distribution. Andreone, Glaw, Nussbaum, Raxworthy, Vences, and Randrianirina, 2003, J. Nat. Hist., London, 37: 2119-2149, discussed the occurrence of this species on Nosy Be Vences, Kosuch, Rödel, Channing, Glaw, and Böhme, 2004, J. Biogeograph., 31: 593-601, studied molecular phylogeography, provided a map of the range, and suggested that this nominal taxon contains at least five cryptic species: (1) the population in Madagascar (which they regarded as having arrived via over-water dispersal), the Seychelles, and Reunion; (2-3) two in West Africa; and (4-5) two in East Africa. Channing and Howell, 2006, Amph. E. Afr.: 306-308, provided an account for East Africa. Minter and Passmore, 2004, in Minter et al. (eds.), Atlas Frogs S. Afr. Lesotho and Swaziland: 286-287, provided an account for South Africa. Padial and De la Riva, 2004, Rev. Esp. Herpetol., 18: 94, provided records of this species, or one of the complex, from Mauritania. Baha El Din, 2006, Guide Rept. Amph.

Pickersgill, 2007, Frog Search: 128-131, provided an account and noted an apparently unnamed species from Arusha, Tanzania, masquerading under this name. Rödel, Brede, Schiefenhövel, Penner, Sinsin, and Nago, 2007, Salamandra, 43: 231–238, reported this species from the Lokoli Forest of southern Benin. Lötters, Wagner, Bwong, Schick, Malonza, Muchai, Wasonga, and Veith, 2007, Fieldguide Amph. Rept. Kakamega Forest: 21-22, provided an account for Ptychadena cf mascareniensis in Kenya. Jacobsen, 2009, Afr. Herp News, 47: 2-20, reported this species from east-north-central Central African Republic. Bwong, Chira, Schick, Veith, and Lötters, 2009, Salamandra, 45: 129-146, discussed the assignment of a population in western Kenya to this taxon and noted that if Ptychadena mascareniensis constitutes a species complex, then the name Rana venusta Werner, 1908, is likely the appropriate name for the northeastern population.
