Baeopelma foersteri
Previously known as Psylla foersteri but now placed in the genus Baeopelma. It is also sometimes written Baeopelma försteri.
This was found by Graham Moates on Alder. He took the specimen to confirm the ID so my photos are in-pot, though you can see the long terminalia and long antennae which characterise this species. It's a site I visit regularly so I hope to find the species again before too long and improve on my photos.
