This paper presents the first record of a rare species of Miridae, Polymerus (Pachycentrum) carpathicus (Horváth, 1882), in Poland. A broad analysis of its occurrence was conducted, which was based on modelling its potential ecological niche using past and future models, which enabled new and valuable information about the potentially suitable habitats and its possible range of distribution as well as its climatic preferences to be identified. The results of the research indicate that P. (P.) carpathicus prefers habitats in highlands and mountains. This species probably came to Europe from Asia via a postglacial migration and the disjunctive range that characterises P. (P.) carpathicus may be due to a lack of data. Additionally, the key to identifying the Polish species from the subgenera Pachycentrum and Polymerus and maps of their distribution in Poland are also presented.
