In my opinion, the one on the left is a female and the one on the right is a male, but the pictures are too blurry to be certain. My main criterion is that the one on the right looks to have the pair of claspers around the vent area that are used during mating, while the one on the left has nothing of the sort, but you should be able to look up guides yourself online with higher resolution photos that will make it clearer. Males of some species also have longer claws.
