Vig Károly: Zoological Research in Western Hungary. A history (Szombathely, 2003)
100 Phylum Arthropoda Figure 12.1. ALADÁR VISNYA in 1945 The leafhoppers collected under the Natural History of the Őrség research programme were processed by ANDRÁS OROSZ (1997). His investigations in the landscape-conservation area yielded 134 species in six families. Six —Arthaldeus arenarius, Cicadula alhingensis, Edwardsiana flavescens, E. spinigera, E. staminata, Eupteryx lelievrei, Macropsis infuscata, Psammotettix nodosus and Sorrhoanus assimilis —were new to the Hungarian fauna. One species (Psammotettix sp.) new to science is in the course of being described. Collections in the Fertő-Hanság National Park in 1995-2000 found 226 species in 113 genera and 9 families. Three species (Eurhadina saageri, Macrosteles oshanini and Metidiocerus elegáns) proved new to the Hungarian fauna, and another four (Edwardsiana salicicola, Eupteryx immaculatifrons, Macrosteles septemnotatus and Rhytiododus nobilis) had been known in Hungary from literary sources but lacked a voucher specimen. The species-level identification of Empoasca (Kybos) sp. aff. austriacus is dubious and calls for further investigation (OROSZ 2002). Order Stemorrchyncha (aphids) The wide-ranging activity of ALADÁR VISNYA (Figure 12.1) included study of whitefly (Aleyrodidae). He wrote a communication on the discovery in Kőszeg of Aleyrodes asari, which had been unreported for 130 years (VISNYA 1935). Further enthusiastic collection in the Kőszeg district demonstrated the occurrence of seven species (VISNYA 1936). (Fauna Regni Hungáriáé gave collection records for only five species within the preTrianon borders of Hungary.) VISNYA'S summary study of the distribution and systematics of the whitefly in Hungary included faunistic data from the West Hungarian border region (VISNYA 1941). He described a species new to science in the Aleurochiton genus, as A. pseudoplatani. 21 He also wrote on whiteflies living on glasshouse orchids. 22 Dreyfusia prelli, of the aphid (Aphididae) family, appeared in the Hungarian fauna as a new pest on conifers. It was first shown to occur in the West Hungarian border region (AMBRUS 1961a). In the Fertő-Hanság National Park, 39 scale-insect species have been found, of which Rhizoecus periolanus is 21 VISNYA, A. 1940.
