Pluskwiaki różnoskrzydłe (Hemiptera: Heteroptera) Cieszyna (Beskidy Zachodnie, południowa Polska) / True-bugs (Hemiptera: Heteroptera) of Cieszyn (Western Beskidy Mts., southern Poland)

This paper presents the results of faunistic study conducted mainly in years 2018–2019 (available material from previous years was also used) on the area of Cieszyn (South Poland). Collected insects have been classified into 198 species, which represented 28 of 32 terrestrial families of the Heteroptera known from Poland. Fourteen of the identified species are recorded for the first time from the area of the Western Beskidy Mts., i.e.: Amphiareus obscuriceps, Brachycarenus tigrinus, Campyloneura virgula, Charagochilus spiralifer, Chilacis typhae, Empicoris culiciformis, Europiella artemisiae, Halyomorpha halys, Leptopus marmoratus, Megalonotus sabulicola, Mermitelocerus schmidtii, Oncotylus viridiflavus, Polymerus palustris and Tingis ampliata. The updated list of true-bugs of this zoogeographical region comprises 468 species. New sites of some rarely sampled species as: Campyloneura virgula, Charagochilus spiralifer, Leptopus marmoratus, Macrotylus quadrilineatus, Mermitelocerus schmidtii and Oncotylus viridiflavus are given. The study presents also new data about alien species in Poland such as: Amphiareus obscuriceps, Deraeocoris flavilinea, Halyomorpha halys, Leptoglossus occidentalis, Orsillus depressus and Oxycarenus lavaterae, as well as species showing northward expansion: Acetropis longirostris, Oxycarenus pallens and Spilostethus saxatilis.
