I've seen lots of large millipedes, but never any with orange stripes and longer antennae like this one.

The closest looking species I could find online without spending too much time is Ommatoiulus sabulosus, but supposedly those re only found in Europe.

Why not post it over on Inaturalist, there are only 16 observations for this species.

Yeah, I should probably make some accounts on other websites. I'm so busy with what I have, I hardly every post anywhere but here.

Californiulus is an interesting genus. Most other large cylindrical millipedes are either spirobolids (such as Narceus) or spirostreptids (such as Orthoporus), but Californiulus and one other genus endemic to the pacific northwest belong to the order Julida, which mostly consists of tiny, common millipedes less than an inch long. 


Last year I encountered Californiulus euphanus in Oregon, which has even longer appendages.
