Alsodes is a genus of alsodid frogs found in Chile and Argentina. It is the most species-rich frog genus in Patagonia. Common name spiny-chest frogs has been coined for them.

Description

Characteristic for this genus is that during the reproductive season, adult males have thorny structures on the fingers and rounded spiny patches on the chest. Breeding takes place in high-elevation streams, and tadpoles have slow development, including overwintering under ice cover.
