Synonymy established by Lindroth (1939b: 80). Etymology. The specific name was proposed for Bjarne Lysholm [1861-1939], a Norwegian physician who turned company manager. Lysholm devoted the last 25 years of his life to natural history and particularly to beetles. He was a founding member of the Norwegian Entomological Society in 1904, served as president of The Royal Norwegian Society of Sciences, and was awarded the Knight’s Cross of the Order of St. Olav for scientific accomplishments.

Distribution.

This Holarctic species ranges from Scandinavia to eastern Siberia and Mongolia (Marggi et al. 2003: 261) in the Palaearctic Region and from the Chukchi coast in Alaska to the Hudson Bay coast in northern Manitoba (Lindroth 1963b: 325); it also occurs quite isolated in the southern parts of the Rocky Mountains in Colorado and New Mexico (Lindroth 1969a: 1114). Fossil remnants of this species, dated between about 16,700 and 18,100 years B.P., have been unearthed in southeastern Iowa (Baker et al. 1986: 96); others, older than 33,000 years B.P., in southwestern Ontario (Warner et al. 1988: 35).
