Oreophrynella quelchii
Oreophryne Quelchii Boulenger, 1895[2] Oreophrynella quelchii, commonly known as the Roraima black frog[4] or Roraima bush toad, is a species of toad in the family Bufonidae.[3] This species is restricted to the transboundary summit of Mount Roraima in Venezuela, Guyana and Brazil, and to the nearby Wei-Assipu-tepui on the Brazil–Guyana border.[2][3] The description was based on one of the several specimens collected from the summit of Mount Roraima by Mr. J. J. Quelch and Mr. F. McConnell.[2][6] The species' natural habitats are high montane tepui environments.There are currently no major threats, although the restricted range of the species makes its vulnerable to stochastic events.
