Craugastor pygmaeus shows strong color polymorphism.[3] Several species have been described and later synonymized with this species,[2][3] but it is in need of taxonomic revision and probably represents a complex of at least five species.[1]
Habitat and conservation
editCraugastor pygmaeus occurs in a great variety of habitats, from lowland forests to montane pine and pine-oak forests and cloud forests at elevations of 400–2,000 m (1,300–6,600 ft) above sea level. It can tolerate some habitat modification as long as shade remains, such as coffee plantations. Development is direct[1] (i.e., there is no free-living larval stage[4]).
Craugastor pygmaeus can be locally common. It can be threatened by habitat and climate change (changing precipitation patterns) leading to the disappearance of shade, humidity and leaf-litter microhabitats. Chytridiomycosis is a potential threat. It occurs in some protected areas.[1]
