C. crawshayi question

[Jesse607]

Does anyone know whether you can accurately guess the sex of a C. crawshayi by the relative thickness of the hind legs. I have a ~4" juvenile that has very thin back legs, and is relatively pale in color. I am guessing that it is male, because I have seen pictures of this species of similar size and they had already, or always had, thick back legs and were a dark maroon color, and mine does not. In other words, I know the adults of this species are sexually dimorphic, and I was wondering if the dimorphism becomes apparent as juveniles. Any second thoughts or opinions are encouraged.....please.

I would just look at the molts, but it shreds them soon after molting deep in its burrow.
