This species is very similar to P. luteitarsis , from which it can only be reliably distinguished in the male sex using features of the male genitalia ( Figs. 21–24 ). In the female, sternite 5 is noticeably wider than long (as in Fig. 14 ), whereas it is longer than wide in P. luteitarsis ( Fig. 16 ). These features are figured by Wolff (1998), who recently records this species from Baden-Württemberg ( Germany).

Distribution: Finland ( Haarto & Kerppola, 2007), Sweden (Bartsch, pers. comm.), Germany (Niedersachsen, Baden-Württemberg), Russia, Siberia ( Speight 2007).

Ecology (based on Speight 2007): preferred environment: forest; deciduous forest, along streams with Alnus and Fraxinus in Quercus /Carpinus/Ulmus forest ( Wolff 1998), in association with Prunus padus close to water. Flowers visited: Prunus padus , Salix . Flight period: end April/mid May.
