ROVARTANI KÖZLEMÉNYEK LIX 1998 pp. 73-78 New data to the caddisfly (Trichoptera) fauna of Hungary, IV S. Nógrádi New data to the caddisfly (Trichoptera) fauna of Hungary, IV. - Two species proved to be new for the Hungarian fauna: Heiicopsyche bacescui Orgh. et Bots, and Limnephilus stigma Curt. The number of recorded Hungarian Trichoptera species increased up to 205. Recent data of some rare species are also presented. An interesting and characteristic caddisfly habitat is introduced. In the past years I reported the first occurrence of 35 species in Hungary and I gave further data to the knowledge of the Hungarian caddisfly fauna in a series of six papers (Nógrádi 1984, 1985, 1986, 1988, 1992, 1994). Further papers present detailed data for certain regions, e.g. for Duna-Dráva National Park (Nógrádi, Uherkovich 1995), East Hungary: Körös Region (Nógrádi, Uherkovich 1996), and also for others, respectivelly. During the last years we continued our intensive field work, mostly in northwest Hungary ("Szigetköz") and along the southwestern border, on the area of Duna-Dráva National Park. At least 100.000 caddisfly adults were collected, captured and determined during the last three years. Besides other small materials were received from colleagues form different parts of the country. In spite of that we visited many new sites, we could hardly find species which were unknown formerly in Hungary. Nothwithstanding many new data of so-called "rare" species were recorded from some localities. The materials mentioned in this paper are deposited in the collection of the Hungarian Natural History Museum, Budapest; Janus Pannonius Museum, Pécs and National Museum of Natural History, Smithsonian Institution, Washington, D.C.
