Pseudosinella sp.? - Pseudosinella rolfsi

Pseudosinella sp.? - Pseudosinella rolfsi
Wayland, Middlesex County, Massachusetts, USA
March 14, 2008
Found under a board at a community garden.

Frans
These weren't with ants, just a group of them under a board in a garden, so I think this is the right identification.

Pseudosinella rolfsi, tentativelly.
Else Cyphoderus similis. Both lack eyes, have scales and a whitish body colour, have a laterally expanded mesothorax ('broad shoulders'). To distinguish them one has to see the furca. Pseudosinella have a very small mucro, while in Cyphoderus it is relatively large.
Also: Cyphoderus lives in ant nests.

Checkout the pictures of Pseudosinella rolfsi that I have IDed in error as 'Cyphoderus similis' (currently still under Cyphoderus similis of Jim McClarin), to see how easy it is to confuse both species. But the furca revealed it was not Cyphoderus but Pseudosinella. Jim still has to move the records...
For the correct ID, see

Frans, we moved that series for Jim
Are any of the other images currently at Cyphoderus misplaced? Put comments on them and we will move them also if necessary. Thanks for all the information you share!

 
Current Cyphoderus images are correct
... as far as I can see. All remaining records are associated with ant nests.
