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).[2] 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.[1]

Taxonomy

Ceuthomantis has been considered to be a monogeneric family Ceuthomantidae,[2][3] but is now merged with Pristimantinae; the oldest name for this taxon is Ceuthomantinae.[4]

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.[5]

Description

Ceuthomantis have T-shaped terminal phalanges and paired, dorsal, gland-like protrusions in the post-temporal and sacral regions; the function of the latter is unknown. They have notched digital discs on the fingers and toes.[1]

Species

The genus contains four species:[2][3]
