Dyschirius aeneolus LeConte, 1850

Dyschirius aeneolus LeConte, 1850: 204. Type locality: Lake Superior (inferred from title of the paper), herein restricted to Marquette, Marquette County, Michigan (see Hubbard and Schwarz 1878: 627). Two syntypes [2 originally cited] in MCZ [# 692].

Dyschirius frigidus Mannerheim, 1853: 123. Type locality: "ad fl. Tchunitén peninsulae Kenai [Alaska]" (original citation). Holotype [by monotypy] location unknown. Synonymy established by Lindroth (1961a: 152).

Distribution.

This species ranges from southern Labrador to the Kenai Peninsula in Alaska (Lindroth 1961a: 152, as Dyschirius frigidus ), south to northern Idaho (Hatch 1953: 67), northeastern Minnesota (Gandhi et al. 2005: 923), northeastern Illinois (Peter W. Messer pers. comm. 2008), and the upper and lower peninsulas of Michigan (Hubbard and Schwarz 1878: 627, 644). The records from Colorado (LeConte 1879d: 500; Wickham 1902: 232), Washington and southwestern Oregon (Herman 1986: 60, as Dyschirius frigidus ; Hatch 1953: 67), and “California” (Leng and Beutenmüller 1894: 184) need confirmation; that from Iowa (Wickham 1911b: 5) is probably in error.
