I recently got a pair of Pachydactylus capensis from a German seller in Hamm. He did not have much information on them. I wanted a female for my big male, and finally bought the pair from this German guy. When I got the animals, I was fairly surprised by the size, color and pattern difference. Here is a pic:

The male I had from Jon Boone is below, and the new male above. The female I got is exactly similar to the latter.
Johan Marais and Terrence Anderson both told me the biggest, yellow form is often found in Southern Gauteng and near Jo'Burg. Can anyone confirm this?
Has anyone an idea about the locality of the smaller, darker form or are they both found in the same places?
Could they possibly be different species?
Thanks in advance for any help.
