Comment

Most closely allied to (and morphologically more primitive than) Hyophryne and Ctenophryne, according to Carvalho, 1954, Occas. Pap. Mus. Zool. Univ. Michigan, 555: 4. 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, did not address this taxon in their study, and they removed Stereocyclops from any subfamily pending resolution of its phylogenetic placement. van der Meijden, Vences, Hoegg, Boistel, Channing, and Meyer, 2007, Mol. Phylogenet. Evol., 44: 1017-1030, did not address this taxon. Pyron and Wiens, 2011, Mol. Phylogenet. Evol., 61: 543-583, assigned this taxon to Gastrophryninae without comment. de Sá, Streicher, Sekonyela, Forlani, Loader, Greenbaum, Richards, and Haddad, 2012, BMC Evol. Biol., 12(241): 1-21, transferred Stereocyclops into Gastrophryninae on the basis of molecular evidence.
