Platydesmid? - Octoglena anura
Gresham, Clackamas County, Oregon, USA

Hi, Bugguide

This millipede was found under a rotting log in an alder forest with sword fern undergrowth. I'm guessing it's platydesmid based on the wide plates and the pink color. Can any of you narrow it down to something more specific?

Moved from Octoglena.

Moved from ID Request.

I believe it is Octoglena anura, but another should confirm before placing at species level.

Do you know how common this species is? Also, do you know of any other species of Polyzonids in the pacific northwest?


I am not as familiar with the millipedes from your area, but from Hoffman's 1999 checklist (1) it appears most of them are found in California and Southwest Oregon.

I would not consider your location SW, but I don't know how strict the ranges are.

There is a link to a downloadable copy of the checklist, it is nice because you can search for terms with ctrl-f.

Oregon Range
I would bet that the range is somewhat strict. Southwestern Oregon has very similar habitat to California, which starts to fade out around Douglas County area.

Thanks for the link to Hoffman's checklist! That is quite the collection of data!
