Calosoma obsoletum Say, 1823

Calosoma obsoleta Say, 1823b: 149. Type locality: "F[or]t Reynolds [Pueblo County], Colo[rado]" (neotype label). Neotype (♀), designated by Lindroth and Freitag (1969: 331), in MCZ [# 33088]. Note. «Arkansa» was the area originally cited by Say (1823b: 150).

Calosoma indistinctum LeConte, 1845b: 208. Type locality: United States of America (inferred from title of the paper). Syntype(s) probably in MCZ. Synonymy established by Breuning (1928a: 110). Note. LeConte’s collection contains six specimens under the name Calosoma obsoletum . Any or all of them could be syntypes.

Calosoma obsoleta microsticta Casey, 1897: 345. Type locality: "Fort Wingate [McKinley County], New Mexico; Kansas" (original citation). Two syntypes [2 ♂ originally cited] in USNM [# 37104]. Synonymy established by Breuning (1928a: 110). Note. Gidaspow (1959: 267) pointed out that of the two specimens in Casey’s collection (USNM) under this name, one belongs to Calosoma lepidum LeConte, the other to Calosoma obsoletum Say. Until a lectotype is designated, the name Calosoma microsticta Casey is listed as a junior synonym of Calosoma obsoletum Say following Breuning (1928a: 110).

Distribution.

This species ranges from Saskatchewan (Lindroth 1961a: 50) to eastern Oregon, south to northeastern Nevada (La Rivers 1947: 136), northwestern New Mexico (Casey 1897: 345, as Calosoma obsoleta microsticta ; McKinley County, UASM) and southwestern Oklahoma (Kondratieff et al. 2005: 171), east to eastern Minnesota (Gandhi et al. 2005: 922). The record from “Texas” (Burgess and Collins 1917: 87) needs confirmation.
