Pithecopus azureus

Pithecopus azureus is a species of frog in the subfamily Phyllomedusinae that lives in Brazil, Paraguay, Argentina, Bolivia, and Peru.

The adult frog measures 31 to 44 mm in snout-vent length. Its eyes are disproportionately large relative to its head. It has very little webbing on its forepaws. The skin of the dorsum is bright green, but it can change color to brown during the day. The ventrum is whitish. There is a green stripe down each side of the hind legs. Some individuals have orange and black stripes the legs.

This frog is in some danger of dying out because of habitat loss. People convert its habitats to soybean farms and sugar cane farms and build dams nearby.
