This species can be found in the Pacific drainages of Tonalá, Chiapas, Mexico, where it occurs on the Pacific versant in the vicinity of Escuintla, south-eastward through southern Guatemala to eastern El Salvador, 400-2,000m asl.
Habitat and Ecology
It inhabits steep, rocky streams primarily in Premontane Wet Forest, but also in Lowland and Lower Montane Wet Forests. Reproduction occurs via direct development. Occurs in second growth forest and shade coffee plantations.
This species is common and persistent in Guatemala and El Salvador. It is abundant in Mexico.
Habitat loss is a major threat. It should be noted that some other species of Eleutherodactylus 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.
It occurs in several protected areas.
This species was previously within the genus Eleutherodactylus (Crawford and Smith, 2005).
