This medium-sized gecko is
easily identified by the pairs of black spots along its ventral surface, and
by the black 'W' at the back of the neck. This nocturnal species occurs in
lowland forest, both primary and secondary, as well as rock crevices, old
buildings and road culverts.
Its eggs are laid in pairs
in the leaf litter or rotting logs, or else adhered to walls or other
man-made structures.
It ranges from Southern
Thailand through Peninsular Malaysia and Singapore to the islands of Borneo,
Sumatra, Java, Sulawesi, the Moluccas, New Guinea and the Philippines.
