Ábrahám Levente: Alderfly (Megaloptera) and lacewing (Neuroptera) fauna of the Villány Hills, South Hungary. - A Villányi-hegység nagyszárnyú (Megaloptera) és recésszárnyú (Neuroptera) faunája.

ÁBRAHÁM, L.: ALDERFLY AND LACEWING FAUNA OF THE VILLÁNY HILLS 257 During this survey very few individuals of alderflies were recorded, since there are no natural watercourses in the Villány Hills, only some artificial fishponds can be found in the northern part of the hill range, where the Pogány-Villány streamlet is dammed. Among the family of neuropteroids, Coniopterygidae show the greatest species richness and almost three quarters of the Hungarian wax fly species live here. According to distribution data of these species in the South Transdanubian region (ÁBRAHÁM 1995, 1998, ÁBRAHÁM, SZIRÁKI 1992) it is evident that the hygrophilous coniopterygids e.g. Coniopteryx aspoecki live only in small populations in the surrounding hills or they may not occur at all. From the populations of Sisyridae and Mantispidae only one of each species was recorded. Considering the species richness of Hemerobiidae the fauna is average, although the number of individuals caught in the samples is quite low. Both the species richness and relative frequency of Chrysopidae meet the requirements. A great variety of biological methods based on DNA analysis, on courting behaviour of males made up of vibrations and acoustic signals, morphological features of egg-laying and larval instars are being used to separate the species, e.g. Chrysoperla carnea, Dichochrysa prasina and Dichochrysa flavifrons (in Italy) complex (HENRY et al. 1996, HÖLZEL 1995, THIERRY et al. 1996). Sometimes these valid species cannot be distinguished from each other on their morphological characters, especially if the recorded material preserved in ethylene glycol was taken for faunistical or ecological investigations. So the Ch. carnea and the D. prasina complex are listed without valid species determination, with quantitative data. I determined Chrysoperla kolthoffi (Navas, 1927) as the most dominant species from the recorded material in the Villány Hills, while Chrysoperla lucasina (Lacroix, 1912) was also found but in average abundance. Both Dichochrysa species - Dichochrysa prasina (Burmeister, 1839) Dichochrysa abdominalis (Brauer, 1856) - were caught. Dichochrysa prasina seems to be more frequent than Dichochrysa abdominalis in the recorded material of 1999-2000. The whole of the material collected in Hungary should be revised so as to get a clear picture of their frequency and distribution. The number of ant lion species seem to be underestimated by this survey. The hypothesis that Libelloides macaronius and Palpales libelluloides may live in the Villány Hills was not confirmed by the present examination, although some suitable habitats for these species were found in the southern part of the Villány Hills. Both species (PONGRÁCZ 1914, STEINMANN 1967) were collected in the Mecsek Mountains, 20 kilometres away from Villány Hills. In the course of this examination several very rare species were collected, so that a short characterisation of them is also given. Aleuropteryx loewii Klapalek, 1894 - It is an expansive Holo-Mediterranean faunal element. Based on its distribution in Hungary it seems to be a rare species and to prefer thermophilous and xerothermic habitats associated with pine species, especially Pinus nigra. The first published specimens recorded by ÚJHELYI (1978) came from Dömörkapu near Pécs and Budaörs near Budapest, i. e. in hilly areas in Hungary. Since then, it has occurred in several similar places but has never been abundant anywhere.
