Elipsocus pumilus
This may well be a common species here but unfortunately the vast majority I catch are males. Males are not safely separable from Elopsocus nuptialis and very difficult to separate from Elipsocus abdominalis or Elipsocus moebiusi, so any males I've caught appear on a separate page for unidentified Elipsocus sp.
This one was a female and from its wing pattern I concluded that it was either Elipsocus abdominalis or Elipsocus pumilus. On clearing the abdomen it became clear that the epiproct had well-defined dark patches at the sides, which pointed to pumilus.
