This species is known only from the Sierra de Omoa on the Atlantic versant of north-western Honduras at 1,470-2,200 m asl.
Habitat and Ecology
It has been found on low vegetation and on the ground of lower montane wet forest. It breeds by direct development and is not dependent upon water.
Fewer than 30 specimens are known, and it is believed to be an uncommon species.
Its habitat is threatened by encroaching subsistence agriculture and forest fires. Chytrid infection has been reported in this species (J. Kolby pers. comm. 2008).
It occurs in the Parque Nacional El Cusuco, and while the protection of this area has been improved in recent years, there is still a need for additional protection of the remaining habitat in the area is needed. Further survey work is needed to determine the current population status of this species as well as the possible impact of chytrid fungus.
Red List Status
Critically Endangered (CR)
Listed as Critically Endangered because its Area of Occupancy is less than 10 km2, all individuals are in a single location, and there is continuing decline in the extent and quality of its habitat on the Sierra de Omoa.
