Agonum basale LeConte, 1846

Agonum basale LeConte, 1846b: 227. Type locality: "ad Rocky Mountains" (original citation); cited from "Nebraska [Territory], near the mountains [probably in present day Colorado]" by LeConte (1854b: 52). One syntype in MCZ [# 5772]. Note. Prior to 1854, Nebraska included the area between the Missouri river and the Rockies from 40°N to the Canadian border.

Platynus vagans LeConte, 1854b: 52. Type locality: "New York" (original citation). Holotype [by monotypy] (♀) in MCZ [# 5773]. Synonymy established by LeConte (1879b: 56), confirmed by Lindroth (1966: 620).

Micragonum concretum Casey, 1920: 83. Type locality: «Illinois» (original citation). Lectotype (♀), designated by Lindroth (1975: 129), in USNM [# 47503]. Synonymy established by Lindroth (1966: 620).

Micragonum concretum amicum Casey, 1920: 83. Type locality: "northern Illinois" (original citation). Lectotype (♀), designated by Lindroth (1975: 129), in USNM [# 47504]. Synonymy established by Lindroth (1966: 620).

Distribution.

This species ranges from "New York" (LeConte 1854b: 52, as Platynus vagans ) and New Jersey (Smith 1890: 85; Smith 1910: 208) to northeastern Colorado (LeConte 1854b: 52), south to northwestern South Carolina (Kirk 1970: 12; Ciegler 2000: 110). The record from “Florida” (Leng and Beutenmüller 1893: 140) is probably in error; that from “Wisconsin” (Bousquet and Larochelle 1993: 258) needs confirmation.
