Found under a rock, this millipede coils like a sweet, with a black spiral and white legs. I think it doesn't have a confusion species, but if it turns out to have then I might have to revisit it
Tachypodoiulus niger, White-legged Snake Millipede
Considering Cylindroiulus londinensis, I thought it looked like we were going to the microscope and keys, but aha! you can actually see the mucronate telson in the lower photo, so I think we're ok!
