Móra, A., Deák, Cs., Kálmán, Z., Lőkkös, A., Soós, N., Csabai, Z.: Contribution to the aquatic insect fauna of Káli-medence and Fekete-hegy, and their surroundings (Balaton Uplands)
Introduction The Balaton Uplands constitute a link between the Lake Balaton and the Bakony Mountains, so it is in close biogeographical connections with both areas. However, this intermediate situation of Balaton Uplands causes that aquatic macroinvertebrate surveys have only focused on the lake or the mountains, and the Uplands have been less considered. Although many papers contain faunistical data on aquatic macroinvertebrates of Balaton Uplands (summarized in MÓRA et al. 2007), these only are results of sporadic investigations. The intensive surveys on this area have recently started (MÓRA et al. 2007). The Káli-medence (Káli Basin) and Fekete-hegy (Fekete Hill) are among the most valuable parts of Balaton Uplands, mainly due to their geological and botanical curiosities. In the area a wide range of standing (small lakes, ponds, marshes, temporary pools) and flowing (springs, brooks, streams) waters can be found, which provide high habitat heterogeneity for aquatic organisms. Unfortunately, the aquatic macroinvertebrate fauna of this area is still poorly known. Sporadic data are known on the fauna of some streams and springs (KOVÁCS 2006; MÓRA et al. 2007; SZEKERES and CSÁNYI 2010; SZÍTÓ 2000). In addition, some data were published concerning aquatic beetles ( CSABAI et al. 2005) and heteropterans (ROZNER 2004). Moreover in cases of some groups, e.g. caddisflies ( SZIVÁK and MÓRA 2009) and some dipterans ( DEÁK and MÓRA 2009; MÓRA 2008a), rarities have been recorded from the area. In this paper new distributional data for some aquatic insect groups (Ephemeroptera, Plecoptera, Heteroptera, Coleoptera, Trichoptera and Diptera: Simuliidae and Chironomidae) from the surface waters of Káli-medence and Fekete-hegy are given, with notes on selected, faunistically important taxa. Material and methods In 2009 and 2010 aquatic macroinvertebrates were collected in 44 surface waters of the Káli-medence and the Fekete-hegy (Table 1), in the frames of "The Natural View of the Bakony" program coordinated by the Bakony Natural History Museum and the 4 TH Biodiversity Day (Szentbékkálla). The specimens were captured by sweeping with a long handled pond net just above the substrate, on water surface, and among the submerged or emergent vegetation. In flowing waters aquatic insects were captured by "kick and sweep" technique. Beyond netting some macroinvertebrates were captured by manual singling from surface of submerged stones, woodstocks, etc. In the case of specimens, which could be identified on field observational data also were taken into consideration. The majority of the captured specimens were preserved in 70% ethyl-alcohol. The aquatic insects were identified on the basis of the following keys and descriptions: BAUERNFEIND (1994), STUDEMANN et al. (1992) for Ephemeroptera; ANDRIKOVICS and MURÁNYI (2002) for Plecoptera; BENEDEK (1969), JANSSON (1986), SAVAGE (1989), Soós (1963) for Heteroptera; ANGUS (1992), CSABAI (2000), CSABAI et al. (2002), HEBAUER (1989), JÄCH (1992, 1998), KODADA and JÄCH (2005), LOHSE (1971), OLMI (1976) for Coleoptera; WALLACE et al. (1990), WARINGER and GRAF (1997) for Trichoptera; BASS (1998), JEDLICKA et al. (2004), JENSEN (1984, 1997), SEITZ (1998) for Simuliidae; BÍRÓ (1981), CRANSTON (1982), HIRVENOJA (1973), JANECEK (1998), KLINK and MOLLER PILLOT 148
