CarolI20A, 700505,Iasi,Romania; [email protected] — Abstract. TheEuropean,North-Africanand CentralAsianspeciesofthegenusNorbanusWalker are revised, providing an illustrated key to males and females of all the species. Three new synonymies are proposed: Norbanusglobulariae (Szelenyi 1941) = Norbanusgiordanii (Ferriere 1952), n. syn.; Norbanus meridionalis (Masi 1922) = Norbanus mordellidarum Dzhanokmen 1999, n. syn.; Norbanusobscurus (Masi 1922) = Norbanus erdoesi (Szelenyi 1974),n. syn. Bothsexes ofN.guyoniare redescribed, and its type locality clarified. A new host record together with distributional data are given for nine out often valid species. The genus Norbanus Walker 1843 (Pter- giordanii (Ferriere 1952), N. globulariae Sze- omalidae: Pteromalinae) consists of 38 lenyi (1941), and N. albicrus (Masi 1934). species distributed all over the world, 13 The latter was later placed in synonymy of which have been described from the with Cyrtoptyx latipes (Rondani 1874) (Pter- West and Central Palaearctic (Noyes 2003), omalidae) by Boucek (1974).
