Mount Duida frogs[1] (Dischidodactylus) form a genus of brachycephaloid frogs endemic to the tepuis of southern Venezuela.[1] The scientific name is derived from the Greek dischidos, meaning divided, and dactylos, meaning finger or toe, in reference to the divided ungual flap (see below).[2]
The family in which Dischidodactylus should be placed is currently uncertain.[3] Amphibian Species of the World currently places it in superfamily Brachycephaloidea with family incertae sedis,[3] while AmphibiaWeb places it in Ceuthomantidae.[4] It had been placed in subfamily Ceuthomantinae within family Craugastoridae based on morphology because no DNA sequence data was available. Dischidodactylus was considered closely related to Ceuthomantis because they share a synapomorphy (completely or almost completely divided ungual flaps) and both genera also have dorsal skin composed of small, flat, pliable (not keratinized) warts, and lack nuptial pads in adult males; they differ in that Dischidodactylus possess a dentigerous process of the vomer, and in that Ceuthomantis lack basal toe webbing.[5]
