Its not tokay its either smithii or siamenis. I personally can't tell from the pic but someone should be able to.
If you know what it is what's the point in asking for help figuring it out.
Where did the animal come from?
To me it looks like a subspecies from tokays - no morph, no G.siamensis or G.smithii! They aren't the result of breeding like most unusual colored tokays.
In China and Vietnam are some populations which look similar to them. They are smaller than nominate tokays, are greenish or grey and life on rocks similar to Gekko siamensis.
It probably is a not yet described species, which should be closely related to G. gecko and G. smithii.

Sadly the only azhari photographs in Roeslers publication are from preserved specimens which of course do look quite different than in life.
And yes..there are similarities to the geckos depicted ihn this thread. But afaik, no geckos have been exported from Bangladesh in recent years.
Also, the "tokay" as aspecies needs a thorough revision. Some of the "colour morphs" and "locales" may turn out to be valid species -or at least subspecies- already after quick and cheap analysis of not only motichondrial DNA but also some relevant nurclear regiuons.

Those pictures were posted almost 2 years ago on this forum by member "Roegbyaj". He called them "Rock Gecko". I've seen some chinese publications about a "Black Spotted Tokay Gecko" which I beleive is the same thing but it did not include any pictures. These geckos are from the Guangxi province of China. If you go a little further south into North Vietnam you will get the normal Tokay Gecko with the red or orange spots.
