voucher specimens H. elongatulus have not been listed in the Hungarian checklist (CSABAI 2010). Unfortunately the collected two specimens were uncolored females, such the Hungarian occurrence of this species needs further confirmation. Hydroporus scalesianus Stephens, 1828 - Central and North European species. In Hungary it only has been recorded from a few localities. This species typically inhabits Sphagnum bogs, but can be collected from other types of dense vegetation. It was still unknown from Balaton Uplands and Bakony Mountains. Laccornis kocae (Ganglbauer, 1904) - L. kocae is the least specialized member of its genus with the most plesiomorphic characters. The distribution area of this species is very narrow and it is very rare everywhere in this area. It is only known from a few localities in Hungary as well, but more than the half of ever known localities can be found in Hungary. The life history of this species is poorly known. Due to its rarity all new record of L. kocae is valuable. Moreover, our results suggest that the ponds on the plateau of Fekete-hegy are typical habitats for this species. Hydrochus megaphallus Berge Henegouwen, 1988 - This species is widely distributed, but rare all over Europe. It has been known only from a few localities in Hungary. H. megaphallus is an acidophilic species inhabiting waters with dense vegetation. Our results suggest that the ponds on the plateau of Fekete-hegy are typical habitats for this species, where, in some cases, it was abundant. Helophorus obscurus Mulsant, 1844 - European species. It is only known from a few localities in Hungary (Bükk, Mecsek, Simontornya). This species inhabits neutral or slightly alkaline waters. Helophorus dorsalis (Marsham, 1802) - European species. The only member of the genus which inhabits shaded forest puddles. These habitats have rarely been studied, such very few records have only been known for this species from Hungary. Laccobius obscuratus Rottenberg, 1874 - This species occurs in Europe and West Asia. It is a crenophil species typically inhabiting springs, streams and pools with cobbles and pebbles. Up to date L. obscuratus has only sporadically been collected in Hungary. Hydraena nigrita Germar, 1824 - European species. In Hungary it is known only from few localities in hilly regions (Aggtelek, Bükk Mountains, Mátra Mountains, Mecsek Mountains, Zemplén Mountains and Zselic). The species are usually found in gravel and accumulated debris in small, slow to moderately flowing forest streams. TRICHOPTERA Synagapetus krawanyi (Ulmer, 1938) (Trichoptera) - It is distributed in the Alps and West Balkan. In Hungary it only has been known from Mecsek and Kőszeg Mountains, and our records are the first ones outside of these two area. The larvae live in springs and spring outlets. S. krawanyi is an endangered species in Hungary ( NÓGRÁDI and UHERKOVICH 2002). Tinodes rostocki McLachlan, 1878 (Trichoptera) - It is widespread in West, South and Central Europe. Although it is known from many mountainous region in Hungary, it is regarded as rare and vulnerable species in our country ( NÓGRÁDI and UHERKOVICH 2002). It is the first time that T. rostocki was collected in Balaton Uplands. DIPTERA: SIMULIIDAE Simulium trifasciatum (Curtis, 1839) - Widely distributed species all over Europe excluding the Mediterranean region. The larvae typically live in small streams in hilly regions. 152
