Comment

In the Rana (Amnirana) albolabris group of Dubois, 1992, Bull. Mens. Soc. Linn. Lyon, 61: 324. See Perret, 1977, Rev. Suisse Zool., 84: 844. Discussed, redefined, and compared with Rana lepus (as Hylarana lepus) by Perret, 1983, Bull. Soc. Neuchatel. Sci. Nat., 106: 109-113. Rödel and Branch, 2002, Salamandra, 38: 251, reported the species in Ivory Coast, and provided some brief comments. See brief comments by Rödel, Bangoura, and Böhme, 2004, Herpetozoa, Wien, 17: 107, regarding range and natural history. Rödel, Gil, Agyei, Leaché, Diaz, Fujita, and Ernst, 2005, Salamandra, 41: 114, provided a record for southwestern Ghana. Segniagbeto, Bowessidjaou, Dubois, and Ohler, 2007, Alytes, 24: 72–90, considered the presence of this species in Togo to be doubtful. See photograph, map, description of geographic range and habitat, and conservation status (as Amnirana occidentalis) in Stuart, Hoffmann, Chanson, Cox, Berridge, Ramani, and Young, 2008, Threatened Amph. World: 475, who noted that records from Nigeria require confirmation. Kouamé, Konan, Adepo-Gourène, Gourène, and Rödel, 2014, Herpetol. Notes, 7: 657–665, provided a record for southeastern Ivory Coast. Rödel and Glos, 2019, Zoosyst. Evol., 95: 26, reported this species from Foya Proposed Protected Area in western Liberia, and commented on habitat preference. Channing and Rödel, 2019, Field Guide Frogs & Other Amph. Afr.: 388–389, provided a brief account, photograph, and range map.
