CSABAI ZOLTÁN – MÓRA ARNOLD – BODA PÁL – CSER BALÁZS – MÁLNÁS KRISTÓF: Contribution to the aquatic insect fauna of the northern part of the Bakony mountains (Ephemeroptera, Coleoptera, Heteroptera and Trichoptera)

The 13 mayfly species found represent 14% of the Hungarian fauna and 43.3% of the fauna known from the Bakony. Siphlonurus armatus (28 sites), Electrogena ujhelyii (17 sites) were the most common species. Baetis pentaphlebodes is new to the fauna of Bakony Mountains. The 97 aquatic beetle species found represent 39% of the Hungarian fauna and 78.8% of the fauna known from the Bakony. The most common species of aquatic beetles were Anacaena limbata (30 sites), Platambus maculatus (22 sites), Hydrobius fuscipes (16 sites). Because of the lack of comprehensive survey on aquatic beetles in the northern part of the Bakony, all of the species found are new to the fauna of this area, 35 species are new to the fauna of the whole Bakony Mountains and its environs (including edge territories and Lake Balaton, in the list below these species marked with asterisk). Based on earlier papers and our recent data a total of 132 aquatic beetle species are known recently from the Bakony Mountains and its environs. The 26 aquatic and semi-aquatic bug species found represent 47.6% of the Hungarian fauna. Nepa cinerea (17 sites), Gerris lacustris (18 sites), and Aquarius paludum (21 sites) were the most common species. Thus far only Nepa cinerea, Notonecta viridis, Aquarius paludum and Gerris thoracicus were recorded from the Bakony Mountains and its environs, so the other 23 species are new to the fauna of this area (marked with asterisk in the list below). The found 31 caddisfly species are 14% of the Hungarian fauna and 31% of the fauna known from the Bakony. Five species proved to be new to the caddisfly fauna of this area: Rhyacophila obliterata, Halesus digitatus, Micropterna nycterobia, Potamophylax cingulatus, Eithax obscurus. The Ironoquia dubia (20 sites), Eimnephilus rhombicus, Potamophylax rotundipennis, Chaetopteryx fusca (17-17 sites) and Limnephilus lunatus (14 sites) were the most common species. Our results suggest that Aranyos-patak (Csesznek), Borostyán-kút (Bakonybél), CuhaiBakony-ér (Réde), Dudari-patak (Bakonyszentkirály), Feketevíz-éri-tavak (Acsteszér), Fekete-ér, Kardosrét (Zirc), Gaja (Bakonycsernye, Szápár) and Gerence, Gerencepuszta (Bakonybél) are the most valuable waterbodies in the northern part of the Bakony mountains. In the list of the species we gave the locality (with administration unit), the date of sampling, the total number of individuals and the names of collectors in alphabetic order. The names of collectors are given by abbreviations as follows: BP - Pál Boda, CsB - Balázs Cser, CsZ - Zoltán Csabai, MA - Arnold Móra, PZs - Zsuzsanna Pap.
