4 species in 1 genus

Tree Frogs

Frogs of the family Ceuthomantidae are found in the Guiana Highlands of northeastern South America (Heinicke et al. 2009). Diagnostic characters include: T-shaped terminal phalanges, adductor musculature of the "S" type, lack of intercalary elements at the digit tips, paired lipid-containing protrusions of unknown function in the post-temporal and sacral regions, a very poorly ossified neurocranium, an unusually massive neopalatine bone, notched digital discs on fingers and toes, and the lack of vomerine teeth. The protrusions resemble dorsal glands but are not true glands. This family is basal within Terrarana (a clade consisting of the families Ceuthomantidae, Brachycephalidae, Craugastoridae, Eleutherodactylidae and Strabomantidae, with the latter four families recognized by Hedges et al. 2008; these families were all originally subsumed within Eleutherodactylus). Ceuthomantid frogs are presumed to have direct development of terrestrial eggs, as do other members of the clade Terrarana.
