Description
Summary:The subgenus Pezocrosita Jacobson, 1901, genus Chrysolina Motschulsky, 1860, currently includes 38 species, being divided into 7 species-groups. Among them, the Chrysolina ( sahlbergiana ) group remains the least studied, although it comprises the type species of the subgenus. The latter, Chrysolina sahlbergiana (Jacobson, 1901a), is shown to encompass 2 subspecies: Ch. sahlbergiana sahlbergiana and Ch. sahlbergiana jacobsoni (Lopatin, 1970) . An amended description of Chrysolina hyperboreica Mikhailov, 2002, a local species endemic to the northern Ural Mountains within Sverdlovsk Province and previously known only from the male holotype, is given based on new material. A new species, Ch. korgonica sp. n., is described from western Altai. A key is given to all the four species of the group. The relict character of the Chrysolina ( sahlbergiana ) group is discussed based on disjunct distributions of its species and their associations with the former tundra-steppe communities.
