to southwestern Sri Lanka where it is found at altitudes of up to above sea level. It does not have a continuous distribution as its range is fragmented into a number of separate locations. Its typical habitat is tropical humid forests where it occurs in the leaf litter on the ground near upland streams. It sometimes climbs into the lower parts of trees and has also been seen on sandbanks beside rivers, in rock crevices, in rotting logs and in holes in trees.
