This species can be found on the lower Caribbean slopes of northern Chiapas, Mexico, and adjacent Guatemala, where it is known from small tributaries that drain into the lower Río Grijalva, at altitudes of 300-350m asl.
Habitat and Ecology
It can be found in premontane wet forest along small tributary streams in which it presumably breeds.
It is known only from the type series.
Habitat loss due to agricultural development is a major threat to this species, and water pollution represents an additional threat.
It is protected in Parque Nacional Laguna Lachúa in Guatemala. 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). The two Guatemalan specimens assigned to this species might represent a new taxon.
