Platynus hypolithos (Say, 1823)

Feronia hypolithos Say, 1823a: 59. Type locality: "Cleveland [Cuyahoga County], O[hio]" (neotype label). Neotype (♂), designated by Lindroth and Freitag (1969: 346), in MCZ [# 33021].

Platynus erythropus Dejean, 1828: 97. Type locality: «Amérique septentrionale" (original citation). Holotype [by monotypy] (♀) in MHNP (Lindroth 1955b: 18). Synonymy established by LeConte (1854b: 41), confirmed by Lindroth (1955b: 18).

Platynidius ontariensis Casey, 1920: 8. Type locality: «Ontario» (original citation). Lectotype (♂), designated by Lindroth (1975: 130), in USNM [# 47384]. Synonymy established by Lindroth (1966: 645).

Distribution.

This species is found from Vermont (Rutland County, CNC) to the lower peninsula of Michigan (Hubbard and Schwarz 1878: 644), including southern Ontario (Lindroth 1966: 646), south to east-central Kentucky (Powell County, CNC). The record from “Iowa” (Bousquet and Larochelle 1993: 263) needs confirmation; that from “Virginia” (Bousquet and Larochelle 1993: 263) is probably in error (Richard L. Hoffman pers. comm. 2009).
