"Diptera are the least known insect order in our rivers, despite their extraordinary diversity and their numerous ecosystem services. 111 Diptera taxa (excluding Chironomidae and Ceratopogonidae) were recorded along the over-all length of the Dordogne River and some of its tributaries. 4 species, Hilara clavipes, Dicranomyia aperta, Rhabdomastix hirticornis and Rhipidia punctiplena are recorded for the first time in France, and the presence of 3 species absent from national databases is confirmed. The interest of Diptera in understanding hydrosystems functioning is discussed in light of the species ecological." . . . "2021"^^ . . . "2021"^^ .
