Calathus gregarius (Say, 1823)

Feronia gregaria Say, 1823a: 47. Type locality: "Phila[delphia] [Philadelphia County], P[ennsylvani]a" (neotype label). Neotype (♀), designated by Lindroth and Freitag (1969: 345), in MCZ [# 33022].

Calathus piceus T.W. Harris, 1828c: 123 (as piceous). Type locality not stated. Syntype(s) presumably lost. Synonymy established with doubt by Harris (1833: 567).

Calathus distinguendus LeConte, 1844: 53 (as distinguenidus). Type locality: «Georgia» (original citation). Lectotype [as holotype] (♂), designated by Ball and Nègre (1972: 486), in MCZ [# 5728]. Synonymy established by LeConte (1854b: 36), confirmed by Lindroth (1966: 543).

Distribution.

This species is found from Cape Breton Island in Nova Scotia (Lindroth 1966: 544) to western North Dakota (Tinerella 2003: 636), south to Nebraska, northern Alabama, and northeastern Georgia (Fattig 1949: 32) [see Ball and Nègre 1972: Fig. 51]. The records from Prince Edward Island (Bousquet and Larochelle 1993: 245, see Majka et al. 2008: 133) and eastern Kansas (Popenoe 1877: 23) need confirmation; those from “Florida,” Texas (Wickham 1896c: 133; Knaus 1905b: 348), and New Mexico (Fall and Cockerell 1907: 159) are likely in error (see Ball and Nègre 1972: 486).
