A species of wide distribution, ranging from Corea to the Malay Peninsula and 
Archipelago, eastwards to New Guinea. Occurs on many of the islands of the Western 
Pacific and Indian Oceans. Also known from Somaliland and St. Helena, and reported 
from the Seychelles by Boettger. As for many Geckos, this wide distribution is probably 
to be accounted for by human introduction through ships.
