This species is known mainly from Yacambú and Terepaima National Parks in Lara State, Venezuela. It has been recorded from 1,200-1,800m asl.
Habitat and Ecology
It occurs along streams and on the forest floor of montane moist and cloud forests. The eggs are laid on land and the male protects the eggs. When they hatch, the male carries the larvae on his back to water where they develop further.
It is a common species and there is currently no evidence of any decline. Healthy populations were found in April 2003 in Parque Nacional Yacambú.
In some parts of the range, populations are affected by the extensive clearing of land for coffee plantations (and specifically by the agro-chemicals associated with the plantations).
Although it is protected in two Venezuelan Andean national parks (Yacambú and Terepaima National Parks), some populations (in Cubiro and Guarico) live outside protected areas. Expanded protection of the montane forest within the species' range is recommended.
