| Summary: | The article provides first records of 20 true bugs species (Heteroptera) from seven families (Lygaeidae, Miridae, Tingidae, Acanthosomatidae, Berytidae, and Saldidae) in Kemerovo Region, Western Siberia, Russia. These species, except two, are known in other regions of the Asian part of Russia, thus, the novel data clarify their up-to-date distribution. Most of true bugs, including an alienHoplomachus thunbergii(Fallén) (i.e. 70% of all species in the study) were found in two botanical gardens (Kuzbasskiy and Orbita) in Kemerovo Region, highlighting the importance of surveying such plantings when running faunal studies and inventories. Two alien species,H. thunbergii(fam. Miridae) andArocatus rufipesStål (fam. Lygaeidae) originating from the European and Far Eastern parts of Russia respectively, were found in the city of Kemerovo and represent novel records for the Asian part of Russia (the former species) and Siberia (the latter species). These species could be introduced to Kemerovo Region with plants for planting, plant material or transported with human vehicles. Further studies would be needed to confirm this hypothesis. Here we provide short synopses of the bionomics, distributional records and trophic associations for all species newly documented in Kemerovo Region. The images of adults and male genitalia are given for the majority of species. The authors are grateful to Prof. R.V. Yakovlev (Altai State University, Barnaul) for his help and support on different stages of this study, A. Ustyuzhanina (Tomsk) for useful comments on early version of the manuscript.
