FOLIA ENTOMOLOGICA HUNGARICA ROVARTANI KÖZLEMÉNYEK LX 1999 pp. 153-164 New Auchenorrhyncha species from Hungary (Homoptera) A. Orosz New Auchenorrhyncha species from Hungary (Homoptera) — Three new species, Tachycixius soosi sp. n., Rhopalopyx brachyanus sp. n. and Psammotettix remanei sp. n. from Hungary are described from the collection of the Hungarian Natural History Museum. Three other taxa, Macrosteles septemnotatus (Fallén, 1806), Paralimnus zachvatkini Emeljanov, 1964 and Psammotettix agrestis Logvinenko, 1966 are first recorded from Hungary. With 50 figures. INTRODUCTION The intense faunistic studies in the newly established national parks of Hungary have produced a vast entomological material of several, less explored insect groups. The elaboration of this material resulted in the discoveries of the three new species described below and of some further species reported here for the first time from Hungary. The semi-automatic methods used during these studies (e.g. the Malaise trap and the D-Vac trap) could also help in the better exploration of certain habitats (e.g. the forest canopy) and giving a good chance for finding the less abundant or even rare species. The taxonomic and faunistical novelties are discussed below, following the sequence proposed by Nast (1972). CIXIIDAE Tachycixius soosi sp. n. (Figs 1-14) The genus Tachycixius W. Wagner, 1939 has been represented in the Hungarian fauna by two species, T pilosus (Olivier, 1791) and T. desertorum (Fieber, 1876). The specimens of the new species were collected in the Bükk Mts (NE Hungary), within the framework of the "Síkfőkút Project" research programme. The Síkfőkút area lies at the south-western part of the Bükk mountains, covered mostly by large patches of turkeyoak forest (Quercetum petreae-cerris). Most of the known specimens were collected by a permanent Malaise trap operating in one of these forest patches, an additional specimen was found in the material of a pheromone trap put in a vineyard nearby the village Demjén, SW of Síkfőkút. This latter site is also surrounded by larger mixed forest patch-
