One last possibility. The Chinese geckos, Gekko chinensis and Gekko
hokouensis have recently become the subject of several evolutionary studies.
It appears that both of these species have a complex evolutionary history and
there are some chromosomal races and hybrid forms that haven't been described
yet as species. With the extremely large range of the Tokay gecko I am sure
that it's possible that it has a similar evolutionary history with several
taxa yet to be described.
That is very interesting. Thanks for the great info. Yes, the large range does make one wonder about cryptic species etc. A salamander analogy would be genetic evidence of species divergence in the slimy group. I would just consider it a color morph if it was not for the unique scalation and form. However....a hybrid or chromosomal variant is a very interesting angle. The Jeff/blue spots of the lizard world in a way...eh? I am heading to try and pin down those references you mention this week.
Its a shame that the Tokay has to be the trash lizard of the pet shop circuit.
Regards and again thanks,
