Comment

See account by Guibé and Lamotte, 1963, Mem. Inst. Franç. Afr. Noire, 66: 601–627. Schiøtz, 1963, Vidensk. Medd. Dansk Naturhist. Foren., 125: 42, provided records for Nigeria. Frétey, 2008, Alytes, 25: 99–172, summarized the literature. See statement of geographic range, habitat, and conservation status in Stuart, Hoffmann, Chanson, Cox, Berridge, Ramani, and Young, 2008, Threatened Amph. World: 627–628. In species group C of Zimkus, Rödel, and Hillers, 2010, Mol. Phylogenet. Evol., 55: 883–900. Onadeko, 2016, Ethiopian J. Environm. Stud. Manag., 9: 22–34, reported on habitat preference (as Phrynobatrachus accraensis) in southwestern Nigeria. Rödel and Glos, 2019, Zoosyst. Evol., 95: 24, reported this species from the Krahn-Bassa Proposed Protected Area in southeastern Liberia and the Foya Proposed Protected Area in western Liberia, and commented on identification, suggesting it is a species complex, and habitat preference. Channing and Rödel, 2019, Field Guide Frogs & Other Amph. Afr.: 292–293, provided a brief account, photograph, and range map. In the Phrynobatrachus natalensis group of Goutte, Reyes-Velasco, and Boissinot, 2019, ZooKeys, 824: 53–70. Kanga, Kouamé, Zogbass, Gongomin, Agoh, Kouamé, Konan, Adepo-Gourène, Gourène, and Rödel, 2021, Amph. Rept. Conserv., 15: 71–107, commented on conservation status, identification, range, breeding behavior, and habitat on the Ivory Coast side of Mont Nimba. van Huyssteen, Petford, Burger, Rödel, Grimes, and Gaugris, 2026, Acta Herpetol., Firenze, 21: 91–106, reported a member of the Phrynobatrachus alleni complex from the Dugbe region of southern Liberia.
