Haris Study on the Palaearctic Dolerus Panzer, 1801 species (Hymenoptera: Tenthredinidae) - In this paper identification keys are given for all Palaearctic Dolerus species. 7 new synonym names are established: Dolerus asceta Jakovlev, 1891 and D. Hi Wei et Nie, 1997 are synonyms of Dolerus cameroni Kirby, 1882; Dolerus thargitai Zombori, 1994 is synonym of D. scoticus Cameron, 1881; D, pseudaeneus Lacourt, 1988 is synonymous with D. aeneus Hartig, 1837; D. kurahashii Togashi, 1981 with D. pakistanicus Muche, 1981; D. nipponicus Haris, 1996 with D. ephippiatus Smith, 1874 and D. persicus Haris, 1996 with D. hispanicus Mocsáry, 1881. D scoticus Cameron, 1881 is revised. Key words: Dolerus, Palaearctic, key, new synonyms. INTRODUCTION The subfamily Dolerinae consists of two genera, namely: Prionourgus Goulet, 1986 and Dolerus Panzer, 1801 according to Goulet's system. In the other system, established by Konow (1890), this genus is also divided into two genera: Dolerus Panzer, 1801 and Loderus Konow, 1890. Goulet (1986) combined the two existing genera (Dolerus Panzer, 1801 and Loderus Konow, 1890 ) together and made a large new genus which he named Dolerus Panzer, 1801 and took out a single species, on which he established a new genus named Prionourgus Goulet, 1986. Goulet divided the genus Dolerus Panzer into seven subgenera and one species group: Dicrodolerus Goulet, 1986; Loderus Konow, 1890; Oncodolerus Goulet, 1986; Dosytheus Leach, 1817; Neodolerus Goulet, 1986; Dolerus Panzer, 1801; Archaeotprion Goulet, 1986 and nitens group. The genus Prionourgus is established on Loderus salmani (Ross, 1935), (syn. Loderus cajonensis Smith, 1980) only. The relationship between the two systems is scheduled here: genus Prionourgus Goulet, 1986 in Konow's system is a member of genus Loderus Konow, 1890. The species of the subgenera Dicrodolerus Goulet, 1986, Loderus Konow, 1890 and Oncodolerus Goulet, 1986 are members of the genus Dolerus Panzer, 1801 according to Goulet (1986), but are members of genus Loderus Konow, 1890 in Konow's system. The species of the subgenera Dosytheus Leach, 1817, Neodolerus Goulet, 1986, Dolerus Panzer, 1801, Archaeotropion Goulet, 1801 and the nitens group are members of genus Dolerus Panzer, 1801 in both classifications. Those species which have large eyes, narrow genae and frequently coloured with white on the thorax are members of the genus Loderus Konow, 1890 and those species which have small eyes, wider genae and
