Psychrophrynella is a genus of small sized frogs restricted to the high Andes of Bolivia and Peru. Currently, 20 species are recognized with few further information on their ecology and/or behavior. They are direct developers, having a reproductive behaviour where eggs are deposited on land, without a free, aquatic tadpole stage.

Psychrophrynella illimani, a critically endangered member of this genus, is the centre of our conservation effort. The species was discovered in 2002 and described to science in 2007 (De la Riva et al. 2007). It is found in a valley on the west flanks of Mt. Illimani, Bolivias second highest peak, hence the species’ name. Few observations were made after its initial discovery and other information about this species is non-existing.
