except vipers, some female vipers have spurs...
i thought i heard there was some sort of paper written about classifying the different candoia species, but i've never seen it. the best way to know what's what is to look at as many live candoia and as many pics as possible, and still you'll make mistakes, but after a while, you can kind of figure out which is which. a while ago i found a paulsoni that looked surprisingly like an australis... but i agree you most definitely have a full sized carinata carinata.
