there is still a great deal unknown about the uroplatus genus.
the "geckos of madagascar..." book by schonecker has, from what i've seen, the most complete listing of Uroplatus anyone has bothered to write about.

as far as the animals available in the trade, it's a little different for you Europeans, where some of you may have locality info on your animals. But here, at least for the vast majority, no locality data is provided for the animals received. But if you want to get a better idea of the ranges of these animals (at least most of them), i suggest you buy the Schonecker and Svatek/van Duin books.
