FOLIA ENTOMOLOGICA HUNGARICA ROVARTANI KÖZLEMÉNYEK LXII 2001 pp. 83-93 Six new Dolerus Panzer, 1801 species from Japan, Turkey and the United States (Hymenoptera: Tenthredinidae) A. Haris Six new Dolerus Panzer, 1801 species from Japan, Turkey and the United States (Hymenoptera: Tenthredinidae) — Key for the Japanese Dolerus Panzer, 1801 species is given. Four new sepcies are described from Japan: Dolerus honshuensis sp. n., D. kurodakensis sp. n., D. rubrosignalis sp. n. and D. takaosanensis sp. n. and compared to D. salmanticensis Vigil, 1988, D. lewisii Cameron, 1885 and D. albolineolatus Haris et Blank, 1996. Dolerus osmanicus sp. n. is described from Turkey, D. rubromaculatus sp. n. from the United States and compared to D. puncticollis Thomson, 1871, D. novograblenovi Malaise, 1931, D. borealis MacGillivray, 1893 and D. rufilobus Ross, 1931. Key words: Dolerus, Tenthredinidae, new species, Japan, Turkey, United States. The first list of the Japanese Dolerus Panzer, 1801 species was compiled by Takeuchi (Takeuchi 1952). In his paper, the following species are listed: Dolerus japonicus Kirby, 1882, D. harukawai Waterston, 1926, D. armillatus Konow, 1896, D. ephippiatus Smith, 1874 (syn. Dolerus umbraticus Marlatt, 1898), D. yokohamensis Rohwer, 1925, D. hordei Rohwer, 1925, D. lewisii Cameron, 1885, D. coreanus Takeuchi, 1927, D. gessneri Ed.

D. pratensis ssp. aterrimus Zhelochovtsev, 1935) and 4 unidentified species. Haris listed the same species from Japan without any addition (Haris 2000). Here I publish the description of four new species and give a key for the Japanese Dolerus Panzer, 1801 species. I studied approximately 1000 Dolerus specimens. 1 received from the National Science Museum (Tokyo) about 700 specimens, the other 300 are from different European and American museums: Hungarian Natural History Museum, Budapest Deutsches Entomologisches Institut, Eberswalde Museum fur Naturkunde, Berlin The Natural History Museum, London
