Assessment Information
Red List Category & Criteria:
Endangered B1ab(ii,iii)+2ab(ii,iii) ver 3.1
Year Published:
2010
Date Assessed:
November 14, 2008
Justification:
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.

Geographic Range
Range Description:
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.

Population
It is an uncommon species.
Current Population Trend: Unknown
Habitat and Ecology (see Appendix for additional information)
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.
Systems: Terrestrial, Freshwater
Threats (see Appendix for additional information)
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.
Conservation Actions (see Appendix for additional information)
It is not known to occur in any protected areas, and protection of remaining tracts of forest habitat in
the Venezuelan Andes is necessary.
