This species is known from a single locality in Venezuelan Guyana: the village of Las Majadas, in Bolívar State, at the merging of the Caura and Orinoco Rivers. It has a very restricted range in a degraded environment, where it has been recorded from 100m asl.
Habitat and Ecology
It occurs in semi-deciduous forests. Its breeding habits are unknown, although larvae presumably develop in water, as with other species of the genus.
It is known from only two specimens, so nothing is known about its population status.
The major threats to this species' habitat are agricultural development, both for crops and livestock, as well as infrastructure development for human settlements. Over-fishing is also a problem.
Its range does not include any protected areas.
