Taxonomic Notes: The family assignment of this genus is uncertain because there are no molecular data for either species of Dischidodactylus. For now, AmphibiaWeb follows Padial et al 2014 in considering this genus as closely related to Ceuthomantis based primarily on two morphological characters whose distribution in other species of Terrarana is unclear. Padial et al. (2014a), in a correction to Padial et al. (2014b), placed Ceuthomantis and Dischidodactylus in the Ceuthmantinae along with Yunganastes. AmphibiaWeb instead recognizes the taxon in the family Ceuthomantidae, and excludes Yunganestes from it following Heinicke et al. (2009)
