Kisfali Máté, Nagy Antal: Summary of the Ortophtera fauna of the Villány Hills (Southwest Hungary)

M. Kisfali & A. Nagy: Summary of the Orthoptera fauna of the Villány Hills (Southwest Hungary) Abstract The Orthoptera fauna of the Villány Hills were assessed on the basis of published distribution data, unpublished results of authors and the Orthoptera collection of the Department of Evolutionary Zoology, University of Debrecen. In the 15 sampling sites of the area 49 Orthoptera species (Ensifera: 23 Tettigonioidea and 2 Grylloidea; 24 Caelifera) were recorded, which makes up 61.7% of the Hungarian fauna. Seven species - Acrida ungarica, Acrotylus insubricus, Isophya camptoxypha, Phaneroptera falcata, Poecilimon fussii, Myrmecophilus acervorum and Tetrix tenuicornis - have no data from the last thirty years. These species probably do not occur in the area. Introduction The Villány Hills has unique fauna and flora with high ratio of Mediterranean species (VARGA & GYULAI 1978, DÉNES 1994, 1998, NAGY& NAGY 2000). Considering orthopterans this region is one of the most studied ones in Hungary (NAGY & RÁCZ 2007a). The first summary of the fauna published by NAGY & NAGY (2000). The large scale databases built from distribution data can be used during scientific analysis (e.g. biogeographical and ecological studies) and conservation activities (e.g. prioritisation and management). The large scale databases are usually biased by dubious taxonomical and geographical data, and preferential sampling (SÓLYMOS & FEHÉR 2005, NAGY & RÁCZ 2007a, 2007b). In 2006 we finished our ten-year study on the Orthoptera fauna and assemblages of the Villány Hills. In order to provide detailed distribution data we summarised published (six papers see in the References and five manuscripts) and our unpublished results. Materials and methods The Villány Hills is located in southwest Hungary. The Szársomlyó, which is one of the first protected area in Hungary (1944), and Fekete-hegy are the protected parts of the Duna-Dráva National Park. We referred 15 sampling sites with different vegetation types on the area (Fig. 1., Table 1.). The data were collected with different sampling methods. Most of the collectors used sweepnetting and direct search which are widely used in orthopterological surveys (Gardiner et al. 2005, Nagy et al. 2007). We made identification of collected specimens based on the identification keys of Harz (1957, 1969, 1975). Considering the species names we followed Nagy (2003). The Isophya brevipennis included in the species list was revised as Isophya camptoxypha (Fieber, 1853) (Heller et al. 2005). A Janus Pannonius Múzeum Évkönyve 1 48
