Beschreibungen/Notizen

• Two new species of Hedychridium (Hymenoptera, Chrysididae) are described (H. tyrrhenicum n. sp. and H. etruscum n. sp.) and the synonymy between H. wolfi Linsenmaier, 1959, from Sardinia, and H. perraudini Linsenmaier, 1968, from Corsica, is established. The geographical distribution of these species is discussed, showing that H. tyrrhenicum is an ancient species of many central Mediterranean islands, while H. wolfi is endemic to the Corso-Sardinian block (including the small islands of Asinara, Capraia, Elba, and Montecristo), and H. etruscum is known only from the Tuscany and Latium coasts and the islands of Elba, Giglio, Gorgona, and Pianosa. In addition, H. etruscum and H. wolfi are the only Chrysididae species known from Montecristo. The geographical ranges of the new species are distinct; H. tyrrhenicum appears to be dominant, in its range, with respect to the widespread H. monochroum, as is H. etruscum on Elba, while the contrary is the case on the Tuscany Mainland; H. wolfi coexists with H. tyrrhenicum and H. etruscum on the Monte Capanne on Elba. The presence of H. carmelitanum Mercet, 1918, in Sicily is confirmed. A key is given for the identification of the Italian species of the H. monochroum group, namely carmelitanum, etruscum, monochroum, and tyrrhenicum.
