It is found in the Cordillera Central, Colombia, from Nevado del Huila southward to the Colombian Massif and the Carchi Province in northern Ecuador.

The toes have only indistinct fringes but bear discs of similar size to the fingers ones; webbing is absent.

The underparts are cream, occasionally with a pink wash.[2] Pristimantis supernatis live in cloud forest, sub-páramo, and páramo at elevations of 2,280–3,500 m (7,480–11,480 ft) above sea level.

Specimens have been spotted under rocks and logs and in deep grass, but also in bromeliads, leaf litter, and in vegetation as high as three meters above the ground.

It is threatened by habitat loss caused by logging and agricultural development (livestock and illegal crops).
