However, specimens collected some 10 km (6.2 mi) from the type locality might belong to this species.

[1] The specific name trachydermus is derived from the Greek trachys (=rough) and derma (=skin).

[2] This species is known from an old-growth premontane wet forest at about 900 m (3,000 ft) above sea level.

[1][2] Craugastor trachydermus is threatened by habitat loss caused by human settlement, agricultural encroachment, and wood extraction.

Chytridiomycosis, an infectious disease, is possibly behind dramatic declines seen in many other stream-dwelling frogs, and could also affect this species.
