What is "ceuthomantis"

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.
