This species is known with certainty only from the type locality in Táchira State, Venezuela (Boca del Monte, Camino del Pregonero), from 2,300-2,800m asl. Other Táchira localities listed in Barrio (1999) are unconfirmed.
Habitat and Ecology
It inhabits mountain streams in cloud forest. The eggs are laid on land and the male protects the eggs. When they are hatched, the male carries the larvae on his back to water where they develop further.
It is an uncommon species.
The major threats are agriculture, involving both crops and livestock, and agricultural pollution, and the area of occupancy of this species is now less than 20km².
It is not known to occur in any protected areas, and protection of remaining tracts of forest habitat in the Venezuelan Andes is necessary.
Red List Status
Listed as Endangered, because its Extent of Occurrence is less than 5,000 km2 and its Area of Occupancy is less than 500 km2, its distribution is severely fragmented, and there is continuing decline in its area of occupancy and in the extent and quality of its habitat.
