Sažetak
The genus Heptatoma contains only one species, Heptatoma pellucens, distributed almost throughout the whole Palaearctic region. Without the author's and collaborator's (J. Mikuska) previous and current research, this species had been recorded in six localities in Croatia. The author's previous unpublished data recorded the species in localities of Donja Bistra, Popovac, Šenkovec, Vinica and Duzluk. The findings of this species in the localities of Branjina, Karanac, Kotlina on Bansko Hill in the Croatian part of Baranja during this year represent new locality records alongside unpublished ones. The total number of recorded localities where Heptatoma pellucens appears in Croatia has increased to 40. From all collected specimens from previous and current research (242), 29.34% (71) of specimens of this species in Croatia were collected during 2022. In the sample collected in 2022, 97.18% of specimens were collected by liquid oil trap (shiny black trays filled with transparent vegetable oil). The sex ratio of the collected specimens in 2022 showed there were 1.7 times more males than females, unlike in previous research where only one male specimen was recorded.
