Comments.

The specimens from Xinjiang share similarities with the European specimens of P. pusillum , as redescribed by Schuppenhauer and Triapitsyn (2018), in having a short median carina on the propodeum and the longest marginal setae on the forewing are ~ 0.7 × the wing width. However, they differ in that the scape of the Xinjiang specimens is smooth, whereas the scape of the European P. pusillum has some faint longitudinal striations.
