Three new species of Chloropidae (Diptera) from southern Sardinia

摘要

During a recent survey of arthropod diversity in several localities of southern Sardinia, three new species of Chloropidae (Diptera) were discovered: Aphanotrigonum lanceolatum sp. nov., Dicraeus sardous sp. nov. and Elachiptera sarda sp. nov. The first is close to A. hastatum Dely-Draskovits from Afghanistan; the second is placed in subgenus Oedesiella Becker; the third is compared to E. cornuta (Fallen, 1820) and E. rufifrons Duda, 1932. The Chloropidae of Sardinia have never been the subject of focussed specific research. Old citations of Chloropidae from Sardinia include those by Costa (1883, 1884a, 1884b, 1885, 1886, 1891), Corti (1909) and Leonardi (1927), while Canzoneri et al. (1995) recorded 36 species (in 17 genera) from Sardinia in general, without further details on their distribution. According to the Fauna Europaea online database (Nartshuk 2004), the current knowledge for this family in Sardinia is 38 recorded species.
