Craugastor pygmaeus, also known as the pigmy free-fingered frog or the pigmy robber frog, is a species of frog in the family Craugastoridae. It is found in western Guatemala and southern Mexico from southern Sinaloa to Chiapas. [1] [2]

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

Craugastor 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]

Craugastor mexicanus is a species of frog in the family Craugastoridae. It is endemic to eastern Mexico and occurs in the states of Oaxaca, Puebla, Hidalgo, and Veracruz.

Although it is adaptable to habitat disturbance, loss of cloud forest is a potential threat to it. Also chytridiomycosis can have negative impacts. It is present in a number of protected areas, including Cofre de Perote National Park, Tehuacán-Cuicatlán Biosphere Reserve, and Cuenca Hidrográfica Río Necaxa.
