New records of Micropezidae, Clusiidae and Periscelididae (Diptera: Acalyptrata) from Portugal

Records of 11 species of three families of acalyptrate Diptera, Micropezidae (4 species), Clusiidae (4) and Periscelididae (3) are given from Portugal. Seven species are new faunal additions to this country, viz. Neria cibaria (Linnaeus, 1761), Neria octoannulata (Strobl, 1899) (both Micropezidae), Clusiodes albimanus (Meigen, 1830), C. caledonicus (Collin, 1912), C. gentilis (Collin, 1912) (all Clusiidae), Periscelis (Myodris) piricercus Carles-Tolrá & Verdugo Páez, 2009 and P. (Periscelis) sp. n. near P. winnertzii Egger, 1862 (Periscelididae). Distribution and biology of all recorded species are reviewed and supplemented with new information based on Portuguese material and notes on the taxonomy and variability of some species are appended.
