Materiały do znajomości Bethylidae (Hymenoptera: Chrysidoidea) Parku Narodowego "Bory Tucholskie", z trzema nowymi gatunkami w faunie Polski

Contribution to the knowledge of bethylid wasps (Hymenoptera, Chrysidoidea: Bethylidae) of “Bory Tucholskie” National Park including three species newly recorded for the Polish fauna.
This article presents the findings of preliminary investigations into the Bethylidae family within the “Bory Tucholskie” National Park, Poland. The research was carried out between 2013 and 2014, with supplementary material collected during 2022-2024. In total, four species were identified, three of which – Bethylus boops (Thomson, 1861), Epyris bilineatus Thomson, 1862, and Goniozus distigmus Thomson, 1862 – are newly recorded for the Polish fauna. Goniozus claripennis (Förster, 1851) had previously been documented in Ojców National Park. The majority of specimens (89%) were obtained from dune firebreak
habitats, with G. distigmus being the dominant species, comprising 93% of the collected material. The hosts of G. distigmus are primarily small moths associated with heather and other plants characteristic of sandy grasslands. As a result of these studies, the Bethylidae family is now represented by ten species in Poland.
