There are actually 2 genera o
There are actually 2 genera of introduced polydesmids here, Polydesmus and Brachydesmus; superficially, they both look pretty much alike, and there is no way to distinguish based on just the size of the "bumps" or polygonal areas on the dorsa. In pretty much any urban environment anywhere in the continental US and Canada, any "flat-backed" milliped like this could be either introduced genus, but most of the time they are a species of Polydesmus, and the most common of these is Polydesmus inconstans Latzel, 1884.

Thanks for the help and explanation.

will move to the main guide page and wait for Dr Shelley

Thanks. I count 18 body segments if that helps.

This is somewhat similiar
to Lynette's which we thought might be Polydesmus. You can check those over and see what you think, but we really have no expertise here.
