Bembidion punctatostriatum Say, 1823

Bembidium punctato-striatum Say, 1823a: 83. Type locality: "Rumney [Grafton County], N[ew] H[ampshire]" (neotype label). Neotype (♂), designated by Lindroth and Freitag (1969: 335), in MCZ [# 33072].

Bembidium sigillare Say, 1830c: 24 [nomen dubium]. Type locality: "Missouri [Territory]" (original citation). Syntype(s) lost. Synonymy established with doubt by LeConte (1857a: 4).

Bembidium stigmaticum Dejean, 1831: 83. Type locality: «Amérique septentrionale" (original citation). Holotype [by monotypy] in MHNP (Lindroth 1955b: 13). Synonymy established, under the name Bembidium sigillare Say, by LeConte (1847: 451), confirmed by Lindroth (1955b: 13).

Distribution.

This species shows a disjunct distribution. In the east, it ranges from Nova Scotia (Majka et al. 2007: 8), Maine, and southern Quebec south to the District of Columbia and Kentucky; in the west it occurs from western North Dakota and Saskatchewan to southwestern British Columbia, north to northern Northwest Territories and southwestern Alaska (Elias 1988: 41) [see Maddison 1993: Fig. 268]. I have also seen one specimen from northwestern Colorado (Eagle County, CMNH). The records from “Missouri,” “Arkansas” (Hayward 1897: 47), southwestern Iowa (Wickham 1911b: 6), “Washington” and “Oregon” (Hatch 1953: 81) need confirmation; that from “California” (Hayward 1897: 47) is probably in error.
