Sphaeroderus schaumii Chaudoir, 1861 View in CoL

Sphaeroderus schaumii Chaudoir, 1861b: 500. Type locality: «Ohio» (original citation), herein restricted to South Bass Island in western Lake Erie (see Will et al. 1995: 68). Holotype [by monotypy] (♂) in MHNP.

Distribution.

This species is known from a small area from Michigan to northern Virginia (Barr 1974a) and western Maryland (Bailey et al. 1994: 320). The record from “Illinois” (Bousquet and Larochelle 1993: 78) is probably in error.

Records.

USA: DC, MD, MI, OH, VA, WV

Note.

Roeschke (1907a: 266), Lindroth (1961a: 29), Lorenz (2005: 64), and Erwin (2007a: 170) listed this taxon as a subspecies of Sphaeroderus nitidicollis Guérin-Méneville. Thomas C. Barr, Jr. (pers. comm. 1977) believes it represents a distinct species, though closely related to Sphaeroderus nitidicollis .
