Those have been around for a while now. They were previously sold as Neon blueleg centipedes. They were tentatively Id'ed as Trachycormacephalous sp. (don't know who did the ID or whether or not it's right) There should be some pictures of the one I had in this forum somewhere.
I checked the one of the other 'Neon Blueleg' on Todd's site and since it bore little resemblance to that specimen except for the blue in the legs, I dubbed it something else... But upon checking Atrax's pics, and the other pic on tarantulaspiders it looks the same. Who tentatively ID'ed it?
