''Ceuthomantis'' is a genus of craugastorid frogs. These frogs are distributed in the southern and eastern parts of the Guiana Highlands (Venezuela, Guyana, and Brazil). The generic name is derived from the Greek noun ''mantis'', which means treefrog, and adjective ''keuthos'', which means hidden, in allusion to the hidden existence of this genus in the tepuis of the Guiana Shield.〔 ==Taxonomy== ''Ceuthomantis'' has been considered to be a monogeneric family Ceuthomantidae,〔〔 but is now merged with Pristimantinae; the oldest name for this taxon is Ceuthomantinae. ''Ceuthomantis'' is closely related to ''Dischidodactylus'', with which they share a synapomorphy: completely or almost completely divided ungual flaps. Both genera also have dorsal skin composed of small, flat, pliable (not keratinized) warts, and lack nuptial pads in adult males. They differ in ''Dischidodactylus'' possessing a dentigerous process of the vomer, and in ''Ceuthomantis'' lacking basal toe webbing.
