67. Psychrophrynella guillei

Psychrophrynella guillei


Psychrophrynella guillei is a species of frog in the family Craugastoridae.

The Craugastoridae family diverged from its closest family, between 31 and 59 million years ago, before the major Andean uplift. The species is found east of Chullina in the Province of Saavedra, Bolivia. This locality is on top of the mountain range that separates the valleys of Río Charazani and Río Quillhuacota, on the Amazonian slopes of the Cordillera de Apolobamba. This species has both geographic and altitudinal restrictions in range, and the species occurs in a total area of less than 20km2. The species range is under threat due to traditional agriculture and there is limited connectivity between forest patches. Due to the restrictions in range, it is likely that the predicted effects of climate change, such as the drying up of regions and increased temperatures, will pose a serious threat to this species. Very little is known about the population status of this species and no conservation measures are currently known for this species.
