Ceuthomantis new genus

Type species. Ceuthomantis smaragdinus Heinicke, Duellman, Trueb, Means, MacCulloch , and Hedges, 2009.

Diagnosis. Same as for family. Members of the genus Ceuthomantis are unique compared to the strabomantid genera Dischidodactylus and Pristimantis in the Guiana Highlands by having notched digital discs on the fingers and toes and by lacking dentigerous processes of vomers.

Content. Tentatively three species, C. aracamuni (Barrio Amorós & Molina) and C. caveribardus (Myers & Donnelly) , new combinations, plus C. smaragdinus n. sp. described below, are assigned to the genus.

Distribution. The genus is known only from elevations of 493–1540 m in the southern and eastern parts of the Guiana Highlands. These include Mt. Ayanganna and the Wokomung Massif in Guyana, Cerro Aracamuni and Sierra Tapirapecó in the Cerro Neblina Massif on the Venezuela-Brazil border, and possibly Sarisariñama Tepui in southern Venezuela (see Remarks). The species are known from the slopes of the mountains and the tops of tepuis.

Etymology. The generic name is masculine and derived from the Greek noun mantis, meaning treefrog and the Greek adjective keuthos, meaning hidden and alludes to its hidden existence in the tepuis of the Guiana Shield, which became known as the Lost World through the writings of Arthur Conan Doyle (1912).
