This species is known only from the islands of Sumbawa, Rinca, Komodo, and the western part of Flores, in the Lesser Sunda Islands, Indonesia, below 600m asl.
Habitat and Ecology
It lives in bushes and trees in tropical dry forest and shrubland. Breeding is presumably by direct development, with the eggs being laid on the ground.
It is not an abundant species, but is still regularly recorded.
Very little is known about threats to this species, but plans for introducing livestock to the area would be particularly detrimental.
It occurs in Komodo National Park and perhaps other protected areas within its range.
