Remarks. This Holarctic species (see RඈIJගඹൾκ & Bൺඋൻൾඋ 2005) has slightly differently coloured adults in the Palae- arctic and Nearctic Regions. The Palaearctic specimens have the lateral yellow part of the thorax larger, covering (besides the humeral callus) the entire notopleural area (see Fig. 55 ).

Distribution. A widespread Holarctic species (RඈIJගඹൾκ & Bൺඋൻൾඋ 2005); it is frequently recorded from the eastern parts of the Palaearctic Region but disappears westerly, with only scarce records from Europe ( Czech Republic, Latvia, Slovakia, see RඈIJගඹൾκ et al. 2017). In the E. Palaearctic, it is known from Russia (West and East Siberia, Far East), China (Inner Mongolia) and North Korea (see RඈIJගඹൾκ & Bൺඋൻൾඋ 2005; RඈIJගඹൾκ 2006, 2009; RඈIJගඹൾκ et al. 2017; WൺඇǤ et al. 2021; and new records above).
