Vig Károly: Zoological Research in Western Hungary. A history (Szombathely, 2003)

90 Phylum Arthropoda occurs in BRAUER (1876), where Sympecma fusca and Libellula fulva are reported from Fertő without exact localities. MOCSÁRY (1896a) cited both records and PONGRÁCZ (1914) only the one for L. fulva, in neither case with new data. After a long silence, several papers concerning dragonflies in the area, mentioned earlier, were published, so that today there are 53 species known to occur in and around the national park. All have been found in the adult state, while nymphs and exuviae for 48 species have been found. (Those missing are Calopteryx virgo, Lestes dryas, Pyrrhosoma nymphula interposita, Hemianax ephippiger and Somatochlora flavomaculata.) The last is new to the Hungarian fauna (KOVÁCS and AMBRUS 2002b). Order Plecoptera (stoneflies) The earliest stonefly record from the region was given by FRANTISEK KLAPÁLEK (1902), for breeding by Perla marginata in the Kőszeg Hills. Later SÁNDOR PONGRÁCZ (1914) reported the stoneflies P. maxima and P. marginata in Kőszeg. SÁNDOR ÚJHELYI (1979 and 1983) gave occurrences in the region of several species: Leuctra braueri, L. autumnalis, Nemoura dubitans and Protonemura auberti. The occurrence of the last in Kőszeg also appears in an article by JACQUES AUBERT (1966). Faunistic research into aquatic insects has developed very rapidly in the last decade and several new results for stoneflies have been added. TIBOR KOVÁCS and ANDRÁS AMBRUS began to collect stonefly nymphs along with Ephemeroptera (mayflies). Their first communication was of the occurrence of two rare species on the Rába. Agnetina elegantula, found at several points on the Rába (Körmend, Magyarlak, Rábahídvég and Sárvár) and on the Austrian stretch of the Lapines (Königsdorf), is new to the Hungarian fauna. The species Marthamea vitripennis was collected for the first time in Hungary since 1914 (on the Rába, at Rábapatona, on the road to Koroncó—KOVÁCS and AMBRUS 2001b). Their early successes encouraged the authors to search the entire Hungarian length of the Lapines and another stretch of the Rába. They were able to find nymphs of ten stonefly species on the Rába and seven on the Lapines in the 1997- 2000 period. Of these, Besdolus ventralis proved to be new to the Hungarian fauna and investigations so far suggest it is found in this country only on the Rába. The record was based on a male adult collected at Rábahídvég on April 20, 2000 and a nymph collected on April 21, 2000 which ecdysed into an imago on the same day. Nymphs of the Dinocras and Perla species are quite difficult to identify, so that the list gives them as Dinocras cephalotes-megacephala complex and Perla marginata-pallida complex (KOVÁCS and AMBRUS 2001a). The data for the adult specimens in the stonefly collection at the Mátra Museum in Gyöngyös were published in an article by ÁRMIN WEINZIERL, TIBOR KOVÁCS and ANDRÁS AMBRUS. The specimens of 23 species were collected at 45 locations between May 1, 1995 and May 21, 2000. The communication includes several occurrence records from the West Hungarian border region. There are strong populations of breeding Isogenus nubecula on the Lapines at Szentgotthárd and along the length of the Rába between Szentgott-
