Eleutherodactylus cosnipatae Duellman, 1978
Pristimantis cosnipatae is a species of frog in the family Craugastoridae, sometimes known as Rio Cosnipata robber frog. It is endemic to Cusco Department, Peru. It is believed to only occur in the Cosñipata Valley. The specific name refers to this valley.
Pristimantis cosnipatae is a robust-bodied small frog. Head is longer than wide and snout is long and narrow. Forearms are short and robust, and hind limbs are moderately short and robust. Dorsum is finely shagreened and grayish tan to reddish brown in colour, with dark brown markings.
It has been suggested that until Paedophryne amauensis was described in 2012, Pristimantis cosnipatae held the record for world's smallest frog. However, with males in the type series measuring 21.8–29.5 mm (0.86–1.16 in) in snout–vent length, this species is not particularly small.
The call is a soft "wraak".
Habitat and conservation
Its natural habitat is tall montane forest, with some tree ferns and bromeliads and rich undergrowth of mosses and ferns. The species is threatened by habitat loss, primarily due to small-scale agriculture taking place within the valley it inhabits. A part of the range is within the Manú National Park.
