Fazekas Imre: Microlepidoptera Pannoniae meridionalis, V. A Dél–Dunántúl üvegszárnyú lepkefaunája (Microlepidoptera: Sesiidae)

367 Microlepidoptera Pannóniáé meridionalis, № 5 Clearwing moth Region fauna in the South Transdanubian (Microlepidoptera: Sesiidae) IMRE FAZEKAS No complex studies have been published on the Sesiidae fauna of the Hungarian geographical regions. In the present study the Sesiidae species of three counties (Baranya, Somogy, and Tolna) were analyzed in the South Transdanubian region. In Hungary 47 Sesiidae species were recorded so far (ABAFIAIGNER et al. 1896; FAZEKAS 2002; FREINA 1997; ISSEKUTZ 1955b; KOVÁCS 1956; LASTÛVKA & LASTÛVKA 1987; LASTÛVKA 1990). The first complex study on the Hungarian clearwing moth — in the Fauna Hungáriáé series — was made by ISSEKUTZ (1955b). In the following years Lastuvka carried out a taxonomical revision on the material of several museums and private collections, providing a significantly different list of the Hungarian Sesiidae species. In this paper, I intend to give an overview and a critical analysis of the special literature on South Transdanubia. The Sesiidae collections of the museums of Komló and Kaposvár were studied. A comparative analysis of the genital on all the cases of different taxon was carried out. I also gave a list of the foodplant, the flight time of the imago and the name of the localities. I analyzed the Palearctic and the Hungarian distribution of the taxon and the habitat preferences of the species. I have concluded that the occurrence of 33 Sesiidae species can be proved in Hungary so far, which is 70.2 % of the Hungarian fauna. Paranthrene insolita polonica Schnaider, 1939 and the Bembecia albanensis (Rebel, 1818) are new to the region. Synanthedon cephiformis (Ochsenheimer, 1808) Synansphecia muscaeformis (Esper, 1800) disappeared, supposedly died out from the area. Only one protected species Chamaesphecia hungarica (Tomala, 1901) is known. The occurrence of the endangered species is significant (21.2%) at the same time the number of local and rare species is outstandingly high (Table 1.) Synanthedon mesiaeformis (Herrich-Schäffer, 1846) is only known in Somogy County in Hungary (Kaposvár, Darány). This Siberian species is endangered in Hungary, it is worth of regional protection. 39.39% of the regional clearwing moth fauna is originated from the Mediterranean refuges, and the Ponto-mediterranean elements are dominant. The Siberian fauna elements are subdominant (27.27%) but the number of the Holarctic species is relatively high as well (18.18%). The majority of the European species (9.09%) is local and rare (Fig. 13)
