Aquatic Empididae (Clinocerinae and Hemerodromiinae) of the upper course of the Neretva River with updated checklist for Bosnia and Herzegovina

Aquatic dance flies (Empididae) were collected during the “Neretva Science Week” in July 2022 along the upper course of the Neretva River in Bosnia and Herzegovina using sweep nets and an aspirator at 10 sampling sites. Of the19 species recorded in this study, five species are new to the fauna of Bosnia and Herzegovina: Clinocerella sorex (Engel), Wiedemannia angelieri Vaillant, Wiedemannia aquilex (Loew), Wiedemannia ariadne Wagner and Wiedemannia mikiana (Bezzi). In total, 45 species from Bosnia and Herzegovina have now been recorded, belonging to 10 genera. This study represents an important contribution to the knowledge of the aquatic dance fly fauna of Bosnia and Herzegovina and is a significant addition to information about the species distribution in the Balkans.
