I did my homework on this one. I thought it was Tapinella. I dissected it and mounted the subgenital plate and genitalia on a permanent slide. I cleared the rest of the specimen and mounted it in water on a well slide. I keyed it according to (1). Subgenital plate with a T shaped sclerite: yes, Posterior pretarsal claw of each foot foliate, anterior pretarsal claw normal: yes. That takes us to Nanopsocus oceanicus; in this case the "Apterous female creamy white excpt along posterior margin of vertex: maybe. I then looked in Psocopteres Euro- Mediterraneens by Charles Lienhard p. 177-178 and followed his description and images. I'm waiting for the final OK from Mockford, but I think I'm right.
