This species is known from the Andes in the state of Mérida, in Venezuela. It occurs from 200-1,800m asl.
Habitat and Ecology
It inhabits seasonal (semi-deciduous) montane forests. The eggs are laid on land and the male protects the eggs. When hatched the male carries the larvae on his back to water where they develop further.
It is a locally abundant species, but appears to be in decline in some parts of its range. La Marca (1995a) noted population declines in this species in several localities in the Andes of Venezuela.
The main threat to the species is habitat destruction and alteration, due primarily to agriculture (for both crops and livestock), infrastructure development for human settlement in the vicinity of the city of Merida, and tourism development. In addition, pollution may also be contributing to the observed declines.
Its range does not include any protected areas, and expanded protection of the remaining montane forest within the range of the species is recommended.
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 the extent and quality of its habitat, and in the number of mature individuals.
