Species account |
 |
Small (c. 2-3mm) brown barkfly. The species has been recorded on only three occasions (in England). Males have long wings (macropterous) while females are frequently short-winged (brachypterous). |
 |
No areola postica. Macropterous forewing uniformly very pale brown. |
 |
Brachypterous forewing also has no areola postica cell. Unlike the macropterous wing, a number of dark marks are present. |
  |
Female
Subgenital plate (underside of abdomen) has an apical lobe that differs from P. didymus and P. phaeopterus in being broader than long. The ‘arms’ are also wider than in those species and has a small colourless ‘triangle’ just above the apical lobe.

Male
The phallosome (underside of abdomen) has a narrow stem (cf. the wider stems of P. didymus and P. phaeopterus), an almost oval ‘body’ with the black sclerite ‘arms’ prominently crossing.
