Pseudosinella rolfsi
The recent pictures of Tom Murray requires me to reconsider my initial ID as Cyphoderus.
Pseudosinella rolfsi is a Cyphoderus similis 'imposter'.
And it got me fooled...
It also has the broad 'shoulders' of Cyphoderus. But the furca is quite different:
in Pseudosinella the dentes are long and the mucro is very short
in Cyphoderus the dentes are relativelly short and the mucro long
(I should have seen this earlier...)

 
Are they also ant associates
like Cyphoderus?

 
Pseudosinella rolfsi
is not particularly associated with ants. It is very common in the leaf litter layer and has a wide distribution in the USA. It is rarely found in caves.

 
This one was definitely with ants.
I've been finding quite a few white springtails with ants lately. I guess I should post some more images and see what you think of them.

Thanks, John & Jane.
Shame on me for not moving it myself :-) I've got a number of albino white springtails that I've found with ant species and one that I found in litter I collected with some giant ter*mites in California. There were several ant species in the same log so I won't claim they are necessarily ter*mitophilic. (So many photos, so little time to tweak and post!)

 
No problem
we enjoy learning from your images - we owe you for that!
