• We revise the classification of taxa belonging to the genus Maculinea from the East Palaearctic Region. In this region, in addition to the well-known three species: M. arion (Linnaeus, 1758), M. ationides (Staudinger, 1887) and M. teleius (Bergstriisser, [1779] 1778-1780), two additional species occur: M. alcon ([Denis & Schiffermiiller], 1775) (upper and middle Amur River, Primor'e, China Northeast/Manchuria and North Korea) and M. kurentzovi sp. nov. (upper and middle Amur River, Primor'e, China Northeast and North Korea). Lycaena kondakovi (Kurentzov, 1970) described from Primor'e is a composite species: the lectotype if' designated here represents an East-Asian subspecies of M. alcon, but its single paralectotype is a female to be assigned to M. kurentzovi sp. nov. Only limited numbers of specimens have been known with M. alcon kondakovi from lowlands of "Far-Eastern" Russia and China Northeast, but in North Korea we found a conspicuous allied taxon arirang nov. (female unknown), which we treat here as a highland subspecies of M. alcon but which may actually represent a good species. Of kurentzovi, we have found a series of specimens which have so far been mostly confused with M. teleius in various collections. We treat Glaucopsyche xiaheana Murayama, 1991 from western Gansu as a subspecies of M. arion along with other subspecies from the central and western parts of China: M. adon philidor (Fruhstorfer, 1915) from the east end of the Qilian Range as well as Mongolia, the type locality, and M. arion inferna nom. nov., a replacement name for Lycaena talsienluica (OberthUr, 1910) (praeoccupied) from Tibet, Sichuan and Qinghai. Because of the similarity of male genitalia and existence of intermediate forms, we regard M. sinalcon Murayama, 1992 described from Qinghai as a subspecies of M. teleius despite a few significant characteristics of the holotype. East continental Asia may be regarded as the headquarter of the genus Maculinea.
