Enderleinella obsoleta
There seems to have been some uncertainty about the taxonomic position of this species seeing as New has it as a member of subfmaily Paracaecilinae (which is now raised to family level), Wikipedia has it as a member of family Stenopsocidae and UKSI has it as a member of Caeciliusidae.
This was swept from a conifer.
