The phylogenetic relationships of this genus were discussed by Grandison, 1981, Monit. Zool. Ital., N.S., Suppl., 15: 187-215. Frost, Grant, Faivovich, Bain, Haas, Haddad, de Sá, Channing, Wilkinson, Donnellan, Raxworthy, Campbell, Blotto, Moler, Drewes, Nussbaum, Lynch, Green, and Wheeler, 2006, Bull. Am. Mus. Nat. Hist., 297: 129, suggested on the basis of DNA sequence evidence that Didynamipus is most closely related to Nectophrynoides among the exemplars studied by those authors. Smith and Chiszar, 2006, Herpetol. Conserv. Biol., 1: 6-8, implied that this taxon should be considered a subgenus of Bufo; see comment under Bufonidae. Van Bocxlaer, Biju, Loader, and Bossuyt, 2009, BMC Evol. Biol., 9 (e131): 1-10, did not address this genus. Van Bocxlaer, Loader, Roelants, Biju, Menegon, and Bossuyt, 2010, Science, 327: 679-682, suggested that Didynamipus phylogenetically isolated, in the neighborhood of Schismaderma, Churamiti, Nectophrynoides, but not demonstratably close to them. Channing, Rödel, and Channing, 2012, Tadpoles of Africa: 142, suggested that the species is a direct-developer.
