Hello I acquired some Gekko smithii specimens, but I would like to know the visual difference between Gekko smithii (Gekko Stentor) and Gekko Siamensis because I can not find anything about it, except from that Siamensis not vocalize as smithii.

Thanks

Beside's G. Siamensis..I have seen G. Smithii "2 I" and G. Smithi "1 I" and I'm not sure what that's about, but Mr. Boone had them like that on his site.

Edit* Actually he still has all 3 of them up with picture's, here's a link starting with Siamensis, then click nest, and the next 2 picture's after are of the Smithii and Smithi.

Ok thanks, but the little siamensis hatchling is virtually the same as the Smithii ... but I will go talk with Jon Boone about it :)

Thanks again

Smithii has the dark markings on it's head where siamensis has none.

On the Jon Boone website, it have two different Smithii (Smithii and Smithi). The Gekko Stentor are related to Gekko Smithii, right ?

Both species have been traded under the (invalid) name G. stentor.
There are many morphological and color diffeences between smithii and siamensis.
However, the most obvious one is what was already mentioned: The dorsal patterns on the head.
While in siamensis, there is no conspicuous pattern, all G. smithii display (at least) a Y shaped pattern on top of their head.
This alreaedy is obvious in hatchlings. However, in some older specimens, especially from Malaysia and mainly in males, the head pattern in some moods almost fades out, but normally can still be seen in neutral mood.
From my perspective by the way, indonesian and malayan G. smithii may be either seperate subspecies or even seperate species. I hope, at some point in time, this will be matter of some closer revision including sequencing. Some "island populations of G. smithii" are close to being described as seperate species as well.

best regards

Ingo

I do not know if it's just me, or with your explanations Ingo many people labelled Siamensis ...

Maybe I don't look at marks in the right place , but in some photos of Siamensis I found on the Internet, is very much like the Smithii from your description ....

Gekko siamensis | The Reptile Database (http://reptile-database.reptarium.cz/species?genus=Gekko&species=siamensis)

Jon Boone - Geckos, etc (http://www.jonboone.com/index.php?link=galleryphotos&row=670)

Maybe I need more explanation ...

Thanks

Ingo has it right, the RD website is just using the wrong photos and they were actually contacted about that with Jon Boone's link for verification, but nothing has apparently been done about it. Mr. Boone personally knows two of the men who discovered a number of the Gekko species, which is one reason he has been able to photograph and keep so many rare and unusual species.
