Osteocephalus exophthalmus

Osteocephalus exophthalmus is a species of frog in the family Hylidae. It is native to Guyana and Venezuela in South America.[1]
This species was first described to science in 2001. The type specimen was collected in the Pacaraima Mountains in western Guyana.[2] There it inhabited sclerophyll forest habitat and was observed to be active at night.[2]
This is the smallest member of the genus Osteocephalus, measuring just over 3 centimeters in length. Its eyes are described as "large and bulgy" and "huge and protruding" and inspired the specific epithet exophthalmus. They are buff with a black cross shape across the iris; this eye coloration is a main feature that distinguishes the species from other frogs in the genus. Its body is brownish above and cream-colored below, and the back surface of the thighs are black. The vocal sac of the male is not well developed. The skin is mostly smooth with a few tubercles along the dorsal surface and a granular texture to the throat and belly.[2]
After the first specimen was recorded, the species was also discovered living in Guyana's Kaieteur National Park and across the border in Estado Bolívar, Venezuela.[1]
