Sochi region, beach of fast Mzimta river. Near forest river I found P. quadripunctata(?) with large R4+5 appendix and dark spots on ta tp. This Parydra with generaly slightly darkened wings and small appendix (not all specimens even). Is it P. croactata or samething else?

Nikita - has this species got a large bristle on the outer face of the mid coxa? If it has no such bristle, then I'd say it was coarctata. If it has a bristle, then it's something else. P. coarctata normally has a well-developed apical tubercle on the scutellum. The appendix on vein R2+3 is a variable character. In some species it can be present or absent.

In that case it's likely to be coarctata. Unfortunately I don't know all the Palaearctic species well enough to exclude others, but coarctata is known from the Black Sea area.
