Also note the common name "Common Barklice" applies to a family of these insects, so you may come across many species with the same common name.

Psocidae/Common Barklice, Cerastipsocus venosus. Need to be verified! Due to the coloring I don't think it is the other one: Cerastipsocus trifasciatus:

Nice spotting, hope you get an ID.
