Vig Károly: Zoological Research in Western Hungary. A history (Szombathely, 2003)

116 Phylum Arthropoda on ephippium, В. ohtusum, Perigona nigriceps, Anisodactylus poeciloides, Parophonus mendax, Ophonus gammeli, Harpalus progrediens, H. rufipalpis, H. zahroides, Dicheirotrichus obsoletus lacustris, Trichocellus placidus, Poecilus puncticollis, Pterostichus elongatus, P. macer, Molops elatus, Sphodrus leucophthalmus, Laemostenus terricola, Amara convexiuscula, A. famelica, A. gebleri, A. pseudostreuna, A. tibialis, Chlaenius festivus and Dromius longiceps (SZÉL and BÉRCES 2002). LÁSZLÓ ÁDÁM (1992) worked on rare aquatic beetles in the fauna territory, identifying several species that had been recorded in the West Hungarian border region before. These (with collection localities and dates in parentheses) were Peltodytes rotundatus (Fertő, April 1901, leg: F. EHMANN), Potamonectes elegáns (Kőszeg, April 1900, leg: F. EHMANN), Hydroporus melanarius (Csörötnek), H. nigrita (Kőszeg Hills) and Bidessus grossepunctatus (Farkasfa and Magyarszombatfa). In another communication (ÁDÁM 1994a), he examined the distribution of rare beetle species in the Heteroceridae family, of which three deserve mentioning. Heterocerus crinitus and Я. hispidulus have only recorded in the fauna territory in the last few years, from the Őrség and the Bükk Hills, while H. jlexuosus was known only from old specimens probably caught on what is now the Austrian side of Fertő. Many aquatic beetles in the beetle collection of the Mátra Museum in Gyöngyös were collected in the West Hungarian border region. Collection records appear in ÁDÁM (1994b). Specimens collected in the Őrség of aquatic-beetle species in the Haliplidae, Dytiscidae, Laccophilidae, Noteridae, Hydroporidae and Gyrinidae families were identified by LÁSZLÓ ÁDÁM (1996a). Previously, there had only been occasional records of such taxa in the Őrség (ÁDÁM 1992, 1994b and 1996c; HORVATOVICH 1981b). So far, 39 species from these families have been shown to occur, of which Ilybius guttiger, Gaurodytes affinis, G. melanarius, Asternus subtilis, Hydroporus nigrita, H. umbrosus, Hydroporidius melanarius and Bidessus grossepunctatus are typical. Hydroporus foveolatus proved to be new to the Hungarian fauna, although as a typical Alpine species, its occurrence needs confirmation. TIBOR KOVÁCS and ANDRÁS AMBRUS (2001) recorded the occurrence as rare species in the Rába and Lapines of Haliplus obliquus, Platambus maculatus and Orectochilus villosus. Several West Hungarian border region records for the last appear in KOVÁCS et al. (2000b). Numerous Western Hungarian specimens can be found in the aquatic Adephaga collection at the Mátra Museum in Gyöngyös (CSABAI et al. 2001). It is worth mentioning the occurrence in the West Hungarian border region (at Kőszeg, Magyarszombatfa, Szőce and Ivánc) of the rare Central and Northern European species Ilybius guttiger (CSABAI 2000). The checklist of water scavenger beetles (Hydrophilidae, with Sperchidae, Hydrochidae, Helophoridae and Hydraenidae) contains only one rare species from the West Hungarian border region: Enochus ater from near Fertőrákos. This is a Mediterranean species, whose northernmost occurrence localities are in Austria and Hungary (CSABAI and SZÉL 1999). The parts of the Fertő-Hanság National Park investigated have yielded
