LŐKKÖS A: THE WATER BEETLES OF THE NAGY-BEREK AREA 167 Results During a faunistical investigation of Nagy-berek carried out between 2003 and 2009, 136 water beetle species (10 Haliplidae, 60 Dytiscidae, 2 Noteridae, 4 Gyrinidae, 1 Georissidae, 1 Spercheidae, 3 Hydrochidae, 8 Helophoridae and 47 Hydrophilidae species) were recorded from the area. The most important faunistic records are the following: Hydroporus longicornis Sharp, 1871 - North and Central European species. It prefers springs and small streams, as well as marshes and peatbogs. From Hungary it is only known from Ócsa and Trizs ( ÁDÁM 1986, CSABAI & HUBER 2001). Hydroporus melanarius Sturm, 1835 - Palearctic species, it prefers marshes, but it is known from other habitats, such as small forest pools and springs. So far it was known only from a few localities of Hungary: Barcs, Csörötnek, Kőszegi-hegység, Középrigóc, Nádasd, Orfü, Őriszentpéter, Pellérd ( ÁDÁM 1992, 1994, 1996a,b, GIDÓ 1999, GIDÓ & SZÉL 1998, HORVATOVICH 1981a, b). Hydroporus neglectus Schaum, 1845 - North and Central European species. It inhabits mainly small forest puddles. It is very rare in Hungary: Bares, Csaroda, Dabas, Farkasfa, Ócsa ( ÁDÁM 1986, 1996b). Hydroporus notatus Sturm, 1835 - It is known from North and Central Europe to Siberia. It prefers undisturbed marshes and small lakes. So far it was known only from a few localities in Hungary: Bares, Dabas, Kalocsa, Tabdi ( ÁDÁM 1986, HORVATOVICH 1981a, SPEISER 1893). Hydroporus umbrosus (Gyllenhal, 1808) - The distribution of this species includes most of northern and central Europe and Siberia to Kamchatka. It occurs in various types of standing water bodies, most often in those with dense vegetation and in peatbogs. It is very rare in Hungary: Budapest, Farkasfa ( ÁDÁM 1992, 1996a). Laccornis kocae (Ganglbauer, 1904) - It is known only from Hungary, Austria, Croatia, South-Russia and Ukraine, it is very rare throughout. It was collected in open marshes. So far it was known only from few localities in Hungary: Biharugra, Hortobágy, Kétegyháza, Pellérd, Sátoraljaújhely, Tabdi, Tiszacsege, Újszentmargita ( ÁDÁM 1983a, 1983b, 1986, 1996, ÁDÁM & HEGYESSY 2003, CSABAI & MÓRA 2003, HORVATOVICH 1982). Agabus nebulosus (Forster, 1771) - Mediterranean species. It prefers newly created water bodies without vegetation or a layer of organic matter on the bottom, frequently also in puddles. It is rare in Hungary. Agabus striolatus (Gyllenhal, 1808) - A very rare Central and North European species. It prefers astatic temporary waters and shadowed habitats. So far it was known only from few localities in Hungary: Badacsonytördemic, Barcs, Bárdudvarnok, Farkasfa, Kaposvár, Kéleshalom, Lakitelek, Lipótfa, Mosonmagyaróvár, Ócsa, Orfü, Pocsaj, Súr, Szeged, Tabdi and Zalaszántó (ÁDÁM 1986a, CSABAI et al. 2005, 2010b, GIDÓ & SZÉL 1998, HORVATOVICH 1981A,B). Ilybius guttiger (Gyllenhal, 1818) - Central and North European species, prefers largely vegetated permanent stagnant waters, such as fens, marshes and ponds. It was known from a few localities in Hungary: Baja, Csaroda, Farkasfa, Ivánc, Keszthely, Kőszeg, Magyarszombatfa, Nógrádverőce (doubtful record), Sátoraljaújhely, Székesfehérvár, Szőce, Tokaj, Tolcsva, Zamárdi (ÁDÁM 1986, 1992, 1996a, b, ÁDÁM & HEGYESSY 2004, CSABAI et al. 2001, 2010b, ENDRŐDI 1974). Graphoderus zonatus (Hoppe, 1795) - Widely distributed Palearctic species, it is found chiefly in larger, densely vegetated water bodies. It is rare in Hungary. Gyrinus suffriani Scriba, 1855 - An European species which is extremely rare all over its distributional area. It inhabits standing or very slowly flowing waters, usually it could
