ID by Dr Robert Mesibov. He said:- I'm actually not sure that's Ommatoiulus, because I can't see a projection on the tail. No native juliforms have such a projection, but sometimes it's broken off in Ommatoiulus. Because it could either be a damaged introduced Ommatoiulus or a native Juliform, it can't be IDed other than "Juliform millipede".
Hi Harvey I've added info about the tail projection to the species page - just look at the pics: https://canberra.naturemapr.org/Community/Species/Details/20758
