Materiały do rozmieszczenia pluskwiaków różnoskrzydłych (Hemiptera: Heteropte-ra) wybranych obszarów Polski: Podlasie, Puszcza Białowieska, Wyżyna Lubelska, Nizina Sandomierska i Roztocze [Materials to the distribution of terrestrial true-bugs (Hemiptera: Heteroptera) in selected parts of Poland: Podlasie, Puszcza Białowieska, Wyżyna Lubelska, Nizina Sandomierska, Roztocze]

Eastern part of Poland is unevenly examined according to distribution of terrestrial true-bugs. Among well studied zoogeographical regions (Wyżyna Lubelska, Beskid Wschodni, Roztocze), true-bugs fauna of others like Podlasie and Nizina Sandomierska is poorly documented. The paper presents new faunistic data on the occurrence of true-bugs Heteroptera in Eastern Poland. Localities were scattered in 17 UTM squares in  five zoogeographical regions: Podlasie, Puszcza Białowieska, Wyżyna Lubelska, Nizina Sandomierska and Roztocze. In total we present the data concerning 58 true-bug species. Ceratocombus coleoptratus and Microporus nigrita are listed for the first time from Podlasie, whilst Pilophorus confusus, Plinthisus pusillus and Psallus wagneri are new to the fauna of Puszcza Białowieska.
