Berlov, 1996: 11. Type species: Lyperopherus vermiculosus Menetries , 1851 by original designation. Etymology (original). From the name of the river Lena and the Greek pteron (wing, by extension elytron) or the first two syllables of the generic name Pterostichus [ q.v .] [masculine]. Galapterus O. Berlov and Plutenko, 1997: 47. Type species: Pterostichus galae Farkac and Plutenko, 1996 by original designation. Synonymy established by Sundukov (2005: 803). Etymology. From the first name of Plutenko's wife and the Greek pteron (wing, by extension elytron) or the first two syllables of the generic name Pterostichus [ q.v .] [masculine]. Diversity. Eleven species in the arctic, subarctic, and boreal regions of North America (four species) and Asia (ten species, one of them extending to European Russia). Three species are Holarctic. Identification. Lindroth (1966) reviewed the North American species. Budarin (1976) reviewed the world fauna, including two species ( Pterostichus mirus Tschitscherine and Pterostichus rugosus Gebler) that belong, however, to the subgenus Metallophilus Chaudoir. Recently Sundukov (2005) revised all known species and provided a key for their identification. Taxonomic Note. This subgenus has been known for sometimes under the name Lyperopherus Motschulsky (e.g., Ball 1960b: 127; Lindroth 1966: 525).
