6 species (see text) Glossostoma Günther, 1901 — junior homonym of Glossostoma LeConte, 1851 Nelsonophryne Frost, 1987 — replacement name for Glossostoma Melanophryne Lehr and Trueb, 2007 Ctenophryne is a genus of microhylid frogs.

[1] As of 2017, Ctenophryne includes two other genera, Nelsonophryne and Melanophryne, in synonymy.

The latter might represent valid genera, but molecular analyses could not resolve their relationships in a robust way.

Placing Nelsonophryne and Melanophryne in the synonymy of Ctenophryne is an interim measure that avoids paraphyly, until new data might resolve the relationships.

[4] The current definition of the genus is essentially based on molecular phylogenetics rather than morphology.
