132 Phylum Arthropode* extremely successful daytime netting. Their findings confirmed the richness of the caddis fauna of the Kőszeg Hills. Three species new to the Hungarian fauna were found: Hydropsyche siltalai, Plectrocnemia geniculata and Adicella balcanica. So were further specimens of Rhyacophila laevis and Philopotamus ludificatus, which had previously been recorded in the district. The Kőszeg Hills are still the only known location in Hungary for these five species, while for several others, they are among only two or three locations in the country (NÓGRÁDI and UHERKOVICH 1989). Although A. balcanica was later shown as occurring by the Dráva as well, 47 a revision revealed that an error had been made and the Kőszeg Hills have remained the only place where the species is known in present-day Hungary (NÓGRÁDI 2001). The authors continued investigating in 1988-9, when the most material (over 2500 specimens) came from a seasonal light trap near the Malom-árok in Kőszeg. Reassuringly, the caddis fauna of the small streams in the Kőszeg Hills had not been impoverished since the previous investigation period, thanks to the natural conditions and lack of disturbance. After the manuscript of the earlier paper was closed (NÓGRÁDI and UHERKOVICH 1989), a further 3349 specimens of 76 species were found, 9 of them for the first time from there, raising the caddis species count in the district to 97. The most important faunistic finding was of Crunoecia kempnyi, confirming an earlier, uncertain record (NÓGRÁDI and UHERKOVICH 1991). Large numbers of caddis flies were collected with a light trap operated at Szőce in the Őrség in 1982, 1983 and 1984 and by other methods. In 1986, SÁNDOR TÓTH operated a Malaise trap on the banks of the Szőce Brook. Only 254 specimens were caught, but some of the 21 species represented were extremely rare (such as Ptilocolepus granulatus). ÁKOS UHERKOVICH and SÁRA NÓGRÁDI caught 3241 specimens of 84 caddis species over the three-year collecting period (NÓGRÁDI 1987 and 1989). The high species count is evidence of the faunistic and floristic variety of the vicinity. The most important results of the processing were five caddis species new to the Hungarian fauna: P. granulatus, Agapetus delicatulus, Hydropsyche guttata, Phacopteryx brevipennis and Potamophylax luctuosus (NÓGRÁDI 1984, 1985a, 1987 and 1989). Some interesting records also appear in another article by SÁRA NÓGRÁDI (1985b). NÓGRÁDI (1986), among further occurrences in Hungary of some rarer species, gives examples from the West Hungarian border region or the Őrség of A. delicatulus, Chaetopteryx rugulosa and Beraeodes minutus, while another publication (NÓGRÁDI 1988) gives Glossosoma boltoni as a species new to the Hungarian fauna. ÁKOS UHERKOVICH resumed work with the Magyarszombatfa light trap in 1982. The caddis material collected in its second period of operation (1982-5) was again processed by the same pair of authors. The trap caught 4901 male and 16,556 female specimens of 99 species over the three years. It was established from this that Magyarszombatfa has the richest 47 NÓGRÁDI, S., and A.
