Specimens examined.

Site 4: slide BUL-4-2

Notes.

This species is characterised by having a thallus bent approximately at a right angle about one-quarter up the thallus from the holdfast; no other described species shares this feature. This species was originally described from the stonefly family Taeniopterygidae . Our specimens were observed in Nemouridae , a different family in the same Order of insects sharing all characteristics with P. angulatum , although most individuals were immature, measuring 350-380 × 29-33 µm, with the typical thallus with the right angle bend and discoid acellular holdfast, known previously only from France ( Valle 2014a).
