Plectrohyla sagorum

Plectrohyla sagorum (common name: arcane spikethumb frog) is a species of frog in the family Hylidae. It is found in the Sierra Madre de Chiapas from Chiapas (Mexico) to southwestern Guatemala, with a single record from northwestern El Salvador. Its natural habitats are cloud forests at elevations of 1000 – above sea level. Breeding takes place in streams. It is very rare in Mexico and El Salvador but abundant at two Guatemalan sites. It is threatened by habitat loss. Chytridiomycosis might also be a threat.
