Junior homonym of Glossostoma LeConte, 1851 (Turbellaria). Synonymy with Ctenophryne by de Sá, Streicher, Sekonyela, Forlani, Loader, Greenbaum, Richards, and Haddad, 2012, BMC Evol. Biol., 12(241): 1-21.

Ctenophryne Mocquard, 1904, Bull. Mus. Natl. Hist. Nat. Paris, 10: 308. Type species: Ctenophryne geayi Mocquard, 1904, by monotypy.

Nelsonophryne Frost, 1987, Copeia, 1987: 1025. Replacement name for Glossostoma Günther, 1900.

Comment

Probably derived from Stereocyclops according to Carvalho, 1954, Occas. Pap. Mus. Zool. Univ. Michigan, 555: 4. Pyron and Wiens, 2011, Mol. Phylogenet. Evol., 61: 543-583, suggested that Ctenophryne is the sister taxon of Nelsonophryne. Parker, 1934, Monogr. Frogs Fam. Microhylidae: 143, 146, included former Nelsonophryne species in Microhyla; Carvalho, 1954, Occas. Pap. Mus. Zool. Univ. Michigan, 555: 11, resurrected Glossostoma. This action was supported by karyotypic evidence provided by Bogart and Nelson, 1976, Herpetologica, 32: 204. de Sá, Streicher, Sekonyela, Forlani, Loader, Greenbaum, Richards, and Haddad, 2012, BMC Evol. Biol., 12(241): 1-21, placed Nelsonophryne into the synonymy of Ctenophryne.
