Justification: Listed as Critically Endangered because its Area of Occupancy is probably less than 10km2, all individuals are in a single sub-population, and the extent of its forest habitat is declining.

Range Description:	This extremely distinctive species is known only from the immediate vicinity of the type locality in extreme north-western Guatemala, on the eastern slopes of the Sierra de los Cuchumatanes, at 1,310m asl. There has been little nearby sampling and the species may range more widely within the escarpment.
Countries:	Possibly extinct: Guatemala

Population:	The species is known only from 12 specimens collected at the type locality. It has not been seen since 1976, despite recent searches.
Population Trend:	Decreasing

Habitat and Ecology:	It has been collected in both disturbed and undisturbed wet forest (approximately 6,000mm annual precipitation). The animals were found under pieces of wood and logs. It presumably breeds by direct development and is not dependent upon water.
Systems:	Terrestrial

Major Threat(s):	There is severe habitat loss taking place at the type locality due to the settlement of refugees and expanding agriculture.

Major Threat(s):
