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)

Hanság-Földsziget, Izsák, Keszthely; CSABAI 2003b, SCHÖDL 1991). These old specimens are from alkaline waterbodies exclusively. All these data are older than 50 years, so the recent record from Borostyán-kút confirms the occurrence of the species in the Hungarian fauna. Aquarius najas (DE GEER, 1773) — It is distributed in whole Europe, but rare species everywhere. The species is under the protection of the law in many countries in Europe, in Hungary as well. The species inhabits the slow-flowing and standing waters. New to the fauna of the Bakony. Mesovelia thermalis HORVÁTH, 1915 — European species, known from Romania, Ukraine and southwestern territory of Russia. The first Hungarian record of M. thermalis was given from the Borza-Holt-Körös, SE Hungary (Kiss 1999). It is regarded as thermofil species and endemic in the Carpathians (BENEDEK 1970; HORVÁTH 1915, 1923; NIESER 1978; PAINA 1978; STICHEL 1955-56). Its occurrence in the Borostyán-kút is the second published record from Hungary. New to the fauna of the Bakony. Rhyacophila obliterata MCLACHLAN, 1863 - Palaearctic species, it lives in fast-flowing clear streams. It is one of the rarest and endangered rhyacophilids in Hungary, found only in the Northern Mountains thus far (NÓGRÁDI and UHERKOVICH 2002). New to the fauna of the Bakony. Potamophylax cingulatus (STEPHENS, 1837) - The species is distributed in whole Europe. It was found in many mountainous regions of Hungary, but is very rare everywhere and one of the vulnerable caddisflies (NÓGRÁDI and UHERKOVICH 2002). New to the fauna of the Bakony.
