Sphaeroderus stenostomus stenostomus (Weber, 1801)

Cychrus stenostomus Weber, 1801: 43. Type locality: «America» (original citation), herein restricted to Chestertown, Kent County, Maryland (CMNH). Syntype(s) location unknown. Note. This species was described the same year under the same name by Knoch (1801: 190). I have not found a date of publication other than the year for Knoch’s book. According to Evenhuis (1997b: 809), Weber’s book was published before March 1801. Weber is in "prevailing usage" as the author of this taxon.

Sphaeroderus stenostomus aequalis Casey, 1920: 172. Type locality: «Pennsylvania» (original citation). One syntype in USNM [# 46003]. Synonymy established by Erwin (2007a: 171).

Distribution.

This mainly coastal subspecies ranges from southeastern New York (Barr 1974a) and southeastern Pennsylvania (York County, CMNH) south to Wake County in east-central North Carolina (Brimley 1938: 115). The record from northern Georgia (Fattig 1949: 9) probably refers to Sphaeroderus stenostomus lecontei .
