Duellman, 1970, Monogr. Mus. Nat. Hist. Univ. Kansas: 18, included eight genera. Subsequent workers, i.e., Duellman and Trueb, 1976, Occas. Pap. Mus. Nat. Hist. Univ. Kansas, 58: 12, and Maxson, 1977, Syst. Zool., 26: 72, transferred two of these genera, Anotheca and Nyctimantis, into Hylinae. Duellman and Gray, 1983, Herpetologica, 39: 333-358, provided a cladogram of the genera, as did Duellman and Hoogmoed, 1984, Misc. Publ. Mus. Nat. Hist. Univ. Kansas, 75: 33. Duellman, Maxson, and Jesiolowski, 1988, Copeia, 1988: 527-543, discussed the immunological evidence for evolution of hemiphractines. Laurent, 1984, Acta Zool. Lilloana, 38: 19-28, provided a phenetic study of the subfamily (as Amphignathodontinae) and demonstrated the possibility of generic rearrangements. Mendelson, Silva, and Maglia, 2000, Zool. J. Linn. Soc., 128: 125-148, provided a cladogram based on morphology that suggested that Gastrotheca is paraphyletic with respect to Hemiphractus, although this was based on the prior assumption of the monophyly of the group, which was the received wisdom at the time. Darst and Cannatella, 2004, Mol. Phylogenet. Evol., 31: 462-475, suggested on the basis of molecular evidence that Hemiphractinae (sensu lato) is polyphyletic and not closely related to hylids. Faivovich, Haddad, Garcia, Frost, Campbell, and Wheeler, 2005, Bull. Am. Mus. Nat. Hist., 294: 1-370, obtained similar results and transferred "Hemiphractinae" out of Hylidae and into "Leptodactylidae" (sensu lato, a former grade of hyloid frogs, not Leptodactylidae, sensu stricto) to render a monophyletic Hylidae. Wiens, Fetzner, Parkinson, and Reeder, 2005, Syst. Biol., 54: 719-748, also considered the hemiphractines (sensu lato) to not be hylids, but recognized them as a family, Hemiphractidae, strongly supported in their Bayesian analysis and weakly supported by their parsimony analysis. Wiens, Graham, Moen, Smith, and Reeder, 2006, Am. Nat., 168: 579-596 (suppl. inform.), with additional evidence, subsequently found "Hemiphractinae" to be nonmonophyletic in their parsimony analysis but did not provide a Bayesian or maximum-likelihood analysis of those data. 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, concluded on the basis of somewhat different lines of evidence that "Hemiphractinae" as previously considered is composed of three phylogenetically distantly-related taxa which they recognized as families: Amphignathodontidae (Flectonotus and Gastrotheca), Cryptobatrachidae (Cryptobatrachus and Stefania), and Hemiphractidae (Hemiphractus). Wiens, Kuczynski, Duellman, and Reeder, 2007, Evolution, 61: 1886-1899, confirmed the results of Wiens et al. (2005). Guayasamin, Castroviejo-Fisher, Ayarzagüena, Trueb, and Vilà, 2008, Mol. Phylogenet. Evol., 48: 577, most recently considered Hemiphractidae (sensu lato) to form a monophyletic group. See comment under Hylidae. Pyron and Wiens, 2011, Mol. Phylogenet. Evol., 61: 543-583, in their study of Genbank sequences, confirmed the monophyly of this taxon, although continuing their exclusion of Cryptobatrachus from analysis. Blackburn and Wake, 2011, In Zhang (ed.), Zootaxa, 3148: 39-55, discussed briefly the taxonomic history of the group. Vitt and Caldwell, 2013, Herpetology, 4th Ed., provided a summary of life history, diagnosis, and taxonomy. Blackburn and Duellman, 2013, Mol. Phylogenet. Evol., 68 : 709-714, provided a molecular phylogeny of the group, also excluding Cryptobatrachus. Castroviejo-Fisher, Padial, De la Riva, Pombal, Silva, Rojas-Runjaic, Medina-Méndez, and Frost, 2015, Zootaxa, 4004: 1–75, provided a phylogenetic analysis based on molecular and morphological evidence of representatives of all nominal general and provided a subfamilial taxonomy.
