Confidence: It's likely to be this, but I can't be certain.
Notes: I'm sticking my neck out here... It's clearly an Armadillidium species based on the blunt-ended uropods (the bits either side of the telson), and the uropod form, patterning and sharp ends to the tergites makes it almost certainly nasatum... I think. However, this is not one I've ever seen, so please make allowances if I'm wrong... ;o)
