Comment

Myers, 1962, Copeia, 1962: 195-202, reviewed the nomenclatural history of Hylodes; his opinion was followed by Lynch, 1971, Misc. Publ. Mus. Nat. Hist. Univ. Kansas, 53: 1-238. See Bokermann, 1966, Lista Anot. Local. Tipo Anf. Brasil.: 36-38, for discussion of the type localities of the Brazilian forms under Elosia. Heyer, 1982, Proc. Biol. Soc. Washington, 95: 377-385, defined the species groups noted in the species accounts. Heyer and Cocroft, 1986, Proc. Biol. Soc. Washington, 99: 100-109, discussed the Hylodes lateristrigatus group. Pavan, Narvaes, and Rodrigues, 2001, Pap. Avulsos Zool., São Paulo, 41: 407-425, discussed the similarity groups of species and phylogeny within the genus. Nascimento, Pombal, and Haddad, 2001, J. Zool., London, 254: 421-428, also summarized the species groups. Pavan, Narvaes, and Rodrigues, 2001, Pap. Avulsos Zool., São Paulo, 41: 407-425, suggested that the Hylodes asper group is paraphyletic. Nuin and Val, 2005, Amphibia-Reptilia, 26: 139-147, provided evidence for the monophyly of Hylodes. Pyron and Wiens, 2011, Mol. Phylogenet. Evol., 61: 543-583, in their study of Genbank sequences, suggested that Hylodes is paraphyletic with respect to Megaelosia. Weber and Caramaschi, 2013, Zootaxa, 3635: 557-568,  reported on comparative larval morphology of the species.
