Synapturanus Carvalho, 1954, Occas. Pap. Mus. Zool. Univ. Michigan, 555: 17. Type species: Synapturanus mirandaribeiroi Nelson and Lescure, 1975, designated by Opinion 1513, Anonymous, 1988, Bull.

Colombia and Peru east through the Guianas to northern Brazil.
Closely related to Elachistocleis and Myersiella according to Carvalho, 1954, Occas. Pap. Mus. Zool. Univ. Michigan, 555: 18. See Nelson and Lescure, 1975, Herpetologica, 31: 389-397, for a discussion of the taxonomic history and literature of this genus. Formerly in the New World component of Microhylinae; Frost, Grant, Faivovich, Bain, Haas, Haddad, de Sá, Channing, Wilkinson, Donnellan, Raxworthy, Campbell, Blotto, Moler, Drewes, Nussbaum, Lynch, and Green, 2006, Bull. Am. Mus. Nat. Hist., 297: 225, considered Synapturanus to be a basal lineage of the entire Microhylidae and phylogenetically removed from Microhylinae or Gastrophryninae and excluded it from any subfamily pending resolution of its phylogenetic placement. Van Bocxlaer, Roelants, Biju, Nagaraju, and Bossuyt, 2006, PLoS One, 1: 1-6, suggested that Synapturanus is the sister taxon of Scaphiophryninae, but did not name the taxon. van der Meijden, Vences, Hoegg, Boistel, Channing, and Meyer, 2007, Mol. Phylogenet. Evol., 44: 1017-1030, found Synapturanus to be distantly related to other New World microhylids and excluded it from Gastrophryninae. Pyron and Wiens, 2011, Mol. Phylogenet. Evol., 61: 543-583, in their study of Genbank sequences, placed Synapturanus as the sister taxon of Otophryne and in Otophryninae.
