Ectopsocus briggsi sensu stricto

Description

A barkfly with conspicuous dark spots on forewings. Males always have wings longer than abdomen (macropterous) but females occur in both long and short-winged (brachypterous) forms. E. briggsi and E. petersi both have spots on the wings. In general the spots are smaller and less intense on E. briggsi, larger and more intense on E. petersi, but there is  overlap of size and intensity between the two species. The best way to distinguish the two species is by checking their genitalia.
