"Metaphorura affinis" from Polden Hills, Street, Somerset, England, United Kingdom. "Original description on Flickr:" :"Yes, yet another white, blind springtail. I'm a little more definite about the ID of this one than the last time! I found two of them, both with the little projection underneath the anal spines, up on Polden ridge again, where I found Neonaphorura duboscqi."
