Phyllobates thorntoni Cochran and Goin, 1970 Colostethus thorntoni is a species of frog in the family Dendrobatidae.

It is endemic to Colombia where it is known from the Cordillera Central in the Antioquia Department.

Scientists have observed this frog between 1480 and 2500 meters above sea level.

[2][1] The type locality now has the city of Medellín on it, so it is unlikely that these frogs live there now.

Its principal threats are inferred to be habitats associated with agriculture and human habitation.
