Comment

See discussion of taxonomic history by Largen, 1997, Tropical Zool., 10: 73ˆ74, who provisionally retained this taxon in Rana, possibly near to Pelophylax ridibundus, although with internal rather than external vocal sacs. Dubois, 1992, Bull. Mens. Soc. Linn. Lyon, 61: 315 (following Dubois, 1987 "1986", Alytes, 5: 61), placed this in the Hoplobatrachus occipitalis group, but Kosuch, Vences, Dubois, Ohler, and Böhme, 2001, Mol. Phylogenet. Evol., 21: 405, returned it to Pelophylax (in the sense of being a subgenus of Rana). See account, photograph, and map for Eritrea (as "Rana" demarchii) by Largen and Spawls, 2010, Amph. Rept. Ethiopia Eritrea: 163. Channing and Rödel, 2019, Field Guide Frogs & Other Amph. Afr.: 384–385, provided a brief account and range map (as Pelophylax demarchii). Generic assignment requires confirmation. Spawls, Mazuch, and Mohammad, 2023, Handb. Amph. Rept. NE Afr.: 126, provided an account addressing identification, natural history, conservation status, and range.
