Distribution. Rider and Zheng (2002) provided distributional information in China (Anhui, Hebei, Heilongjiang, Jilin, Liaoning, Inner Mongolia). Wide spread Palaearctic species, also introduced to northeastern North American ( Thomas, 1992).

The apex of humeral angle sharp, bifurcate or with a small prominence at the posterior of subapex ( Fig. 19 View FIGURES 19–26 ). Two lateral sides of abdominal venter with evenly shallow punctures, not formed into black belt ( Fig. 15 View FIGURES 13–18 ), but in P. lewisi lateral sides with deep black punctures, and formed into black belts ( Fig. 16 View FIGURES 13–18 ).
