Uncertain :(
Hi! It's possibly a new Isopoda species on BugGuide.net! :)

I was about to say that it's a Chaetophiloscia species from the Philoscidae family. See article from here: http://www.univet.hu/users/ehornung/downloads/cikkeim/CRM2003.pdf.

After the telson and uropodites, however it's more likely a Ligidium sp. from a Ligiidae family, possibly an Asian species.

An image with details of antennae and/or telson would be very useful!

 
Ligidium gracile??
Hi, I would agree with Ferenc that it should be a Ligidium and from what I read about American species it seems Ligidium gracile would be an excellent candidate, but I can't be sure - it would be the first photo online of this species, so nothing to compare to except for some rather schematic/unexact drawings :o(

 
Thanks
Glad I didn't say much in my previous comment, I thought that it looked like the linked image currently in Trichoniscus!

 
Yes, the shape may look simil
Yes, the shape may look similar to Trichoniscids, but not quite the same. Unfortunately I can't say more. I have a feeling that it is a Ligidium, but I'd rather not put it there unless it is really certain.

However, the image now can be put under the label "Woodlice".. :)
Bye! F

Maybe
you could email the contributor of this image and ask him for help?

Or Ferenc Vilisics has commented on some in this area, so maybe email him?
