[1][3][4][5] It is endemic to Borneo and only known from Sarawak (East Malaysia); there are records from at least four localities representing three different divisions (Bintulu, Miri, and Kapit).

Preserved specimens have sandy brown to pale tan dorsal coloration.

In living individuals, small red spots are often present on the larger dorsal tubercles.

[1] The habitat of this species is threatened by logging, leading to a decline in both its extent and quality.

It is present in the Gunung Mulu and Pulong Tau National Parks; while the former is well protected, the latter is not and faces encroachment from logging companies.
