Ectopsocus petersi No areola postica. Prominent dark marks where veins meet wing edge (much more prominent than any other British Ectopsocus species).
Ectopsocus petersi Ectopsocus petersi Female
Subgenital plate (underside of abdomen) has pair of colourless apical lobes with the inner margins parallel (cf. E. briggsi). The tips of the lobes have several long hairs.
