Small lowland species of the Sierra de Juarez. It is known from the holotype, a male of 1.95 cm SVL. The nostril is very big and oval, the nasiolabial area is well developed, and the limbs are rather long. Hands and feet are narrow but well developped. The tail is rather long and thick, the color is dark grey/brown with a bronze green dorsal stripe from the back of the head to the base of the tail where it disappears with the dark color. Some light spots are on the flanks and other body parts. Ventral parts are slightly lighter than the flanks.

Habitat & Range : It was collected under bark on the ground, in a low altitude cloud forest near the locality of Vista Hermosa, on the north side of the Cerro Pelon, Atlantic side of the Sierra de Juarez (Oaxaca) at an altitude of around 1500m, in the same area as T. smithi, from which it differs by the lack of maxillary teeth and the shape of the nostrils and fingers. 17Km².

Conservation : Data deficient.
