Abstract. Based on a two-year survey between 1999-2000, altogether 3255 individuals belonging to 59 neuropteroid species (Megaloptera, Neuroptera) were recorded in the Villány Hills. The author gives a complete list of species with the faunistical data and short zoogeographical evaluation illustrated by some distribution maps of the rarest species: Aleuropteryx loewii, Aleuropteryx umbrata, Helicoconis lutea, Coniopteryx renate, Nineta guadarramensis, Chrysopa walkeri, Chrysoperla mediterranea. The typical habitats of the Villány Hills are described based on their rare characteristic neuropteroids and the dominance distribution of the abundant species. A drawing of the profile of the hill range is also given to illustrate the distribution of the species in the different habitats of the Villány Hills. Introduction The Villány Hills, 25 km long in east-west direction and reaching an average height of 240-300 m above the sea level, belong to the South Transdanubian lowland, South Hungary (MAROSI, SOMOGYI 1990). Based on its structural features, the area is divided into three different parts. The western section is formed by low calcareous hills covered by loess. Its present day surface is characterised by incised loess valleys. The hills between the village Túrony and the town Villány form a homogeneous plateau which is almost completely covered by loess on its northern side and is steep and rocky in the south. The third part of the Villány Hills consists of different independent hills with steep cliff slopes especially on the southern sides; the highest ones are Szársomlyó at Nagyharsány and Vár-hill in Siklós (LOVÁSZ 1977). The climate of the area with sub-Mediterranean influences is moderately warm and humid due to its geographical location and morphological features. In the Villány Hills the long vegetation season reinforced by microclimatological influences is very favourable for the flora and the fauna. The annual mean temperature is 10.5 C°, although its value is higher, 11 C°, on the slopes facing south, due to the distribution of solar radiation. Annual precipitation amounts 670-690 mm. The Villány Hills belong to the phytogeographical district of Sopianicum, the region of Praeillyricum (PÓCS 1981). because of its geographical location in the country, the greatest number of Mediterranean flora elements are found here in entire Hungary. Szársomlyó hill, the highest hill (442 m) of the range is especially rich in such unique flora elements. Only very few data (ÁBRAHÁM 1991, ÁBRAHÁM-PAPP 1996) are known on the neuropteroid fauna of the hills, i. e. 44 individuals belonging to 7 lacewing species have been published.
