Sphaeroderus stenostomus lecontei Dejean, 1826

Cychrus stenostomus Say, 1823a: 72 [primary homonym of Cychrus stenostomus Weber, 1801]. Type locality: North America (inferred from title of the work). Syntype(s) lost. Note. Say (1823a: 72) described this taxon as a new species as indicated by the presence of an asterisk preceding the specific epithet. Say did not originally indicate the area where his specimen(s) came from but later (Say 1828: [101]) noted that the species "is not uncommon in Pennsylvania" and that he received a specimen "taken in Massachusetts."

Sphaeroderus lecontei Dejean, 1826: 15. Type locality: «Amérique septentrionale" (original citation), restricted to "Rumney [Grafton County], New Hampsh[ire]" by Lindroth (1961a: 29). One possible syntype in MHNP (Lindroth 1955b: 12). Synonymy established by Roeschke (1907a: 263).

Sphaeroderus niagarensis Laporte, 1833: 390. Type locality: «île que forme la chute du Niagara" (original citation). Syntype(s) location unknown. Synonymy established by Chaudoir (1861b: 496).

Sphaeroderus lecontei diffractus Casey, 1914: 25. Type locality: "New Brunswick" (original citation). One syntype in USNM [# 46002]. Synonymy established by Lapouge (1933: 706), confirmed by Lindroth (1961a: 29).

Distribution.

This subspecies is found from Newfoundland (Lindroth 1955a: 21) to southeastern Manitoba (Lindroth 1961a: 29), south to east-central Iowa (Wickham 1888: 81, as Cychrus stenostomus ; Lindroth 1961a: 29), northeastern Mississippi (Tishomingo County, CNC), northern Alabama ( Löding 1945: 11; Madison County, CNC), northern Georgia (Fattig 1949: 9), and southern South Carolina (Ciegler 2000: 30). The records from east-central Missouri (Summers 1873: 133) and southeastern Louisiana (Summers 1874a: 79) need confirmation; that from “Saskatchewan” (Bousquet and Larochelle 1993: 78) is in error.
