Alsodes nodosus

Alsodes nodosus (common name: black spiny-chest frog) is a species of frog in the family Alsodidae endemic to central Chile; records from Argentina are not considered valid.

Alsodes nodosus is locally common but is getting rarer. It is found in temperate shrubland and seasonal and permanent streams. It is not tolerant of habitat destruction, and urban sprawl is rapidly destroying suitable habitat.
