Atelopus tamaensis La Marca, García-Pérez, and Renjifo, 1990 Atelopus tamaense, the Tamá harlequin frog or Venezuela stubfoot toad, is a species of toad in the family Bufonidae.

It is endemic to the Páramo de Tamá on the Venezuelan-Colombian border and occurs in Apure and (likely) Táchira states of Venezuela and Norte de Santander Department on the Cordillera Oriental of Colombia.

[1][2][3] Its natural habitats are sphagnum bogs in páramo ecosystems[1] as well as upper montane forests[3] at elevations of 2,950–3,200 m (9,680–10,500 ft) above sea level.

[1][3] The species occurs in the Tamá National Natural Park in Colombia and El Tamá National Park in Venezuela.

Its major threat, however, is chytridiomycosis that has negatively impacted many other montane Atelopus species.
