Urkuphryne, also known as the Merino leaflitter frog, is a monotypic genus of frogs in the family Strabomantidae. It is endemic to the Cerro Golondrinas forest area of northern Ecuador. Phylogenetic analyses have recovered "Urkuphryne" as the sister taxon to the smaller "Phyllonastes" within the subfamily Holoadeninae. Autapomorphic characters of this taxon include reduced distal expansions of the fingers and toes and the presence of protruding vomerine teeth. Like other brachycephaloid frogs, "Urkuphryne" individuals mature via direct development, meaning that they do not go through metamorphosis or have tadpoles; instead, hatchlings demonstrate adult features and proportions.
