Comments: A previously overlooked Eucnemis zaitzevi Mamaev, 1976 formerly known from Siberia and Russian Far East recently has been showed to occur in Eastern Europe ( Estonia, Finland and Ukraine) ( Muona 2019). In spite of this fact, Eucnemis specimens from Kaliningrad region (material collected in 2015–2021 years) were re-examined using new key ( Muona 2019). The species E. capucinus is confirmed for the Kaliningrad region and comparatively often occurs in local fauna at eastern periphery of main distributional area.
