This species is known only from the type locality on the northern slopes of the eastern portion of the Sierra de las Minas, near Aldea Vista Hermosa, Guatemala, at 600-650m asl. It might occur more widely.
Habitat and Ecology
It has been found only in undisturbed forest habit transitional between premontane moist and premontane wet forest. Animals were found on or under rocks, and on leaf-litter near streams. This species presumably breeds by direct development, with eggs that are laid on land.
The population status of this species is unknown.
It is facing habitat loss due to expanding agricultural activity and wood extraction. Water pollution is also likely to be a problem.
It occurs in the Reserva de la Biósfera Sierra de las Minas. It should be noted that some other species of Craugastor that are associated with streams have undergone dramatic declines and disappearances, possibly due to chytridiomycosis, so the status of this species should be monitored carefully.
This species was previously within the genus Eleutherodactylus (Crawford and Smith 2005).
