New data on hoverfly fauna (Diptera: Syrphidae) of Bosnia and Herzegovina

Hoverflies (Syrphidae) are a large Dipteran family, distributed almost worldwide. They play very important ecological roles such as plant pollination, nutrient recycling and predation of plant pests. The members of the genus Epistrophe Walker, 1852 are medium-sized hoverflies of which about 75 species have been described in the World, and 12 of them occur in Europe. During a survey, conducted from 16th June to 4th July 2021 at Blidinje Nature Park (Bosnia and Herzegovina), a new species, of the fauna of Bosnia and Herzegovina, was recorded – Epistrophe diaphana (Zetterstedt, 1843) and new records for species Epistrophe leiophthalma (Schiner & Egger, 1853) were observed. Specimens were collected from inflorescences of Common Hogweed (Heracleum sphondylium L.). Information about the records, species habitats, distribution and status in the country and the region is presented and discussed in this research work.
