Type locality: "Camp Hill[s] [Cumberland County], P[ennsylvani]a" (neotype label). Neotype (♂), designated by Lindroth and Freitag (1969: 343), in MCZ [# 33026]. Note. Say (1823a) did not indicate the area where his specimen(s) came from but later (Say 1825: [53]) noted that the species was "an inhabitant of Pennsylvania." Dicaelus dejeanii Dejean, 1831: 687. Type locality: "Amerique septentrionale" (original citation), restricted to "coastal plain of Georgia" by Ball (1959: 126). Holotype [by monotypy] (♀) in MHNP (Lindroth 1955b: 17). Synonymy established by Brulle (1835c: 282). Dicaelus planicollis LeConte, 1847: 427. Type locality: "Georgia ad montes" (original citation). Holotype [by monotypy] (♀) in MCZ [# 5709]. Synonymy established by Ball (1959: 130). Dicaelus carolinensis Casey, 1913: 150. Type locality: "Southern Pines [Moore County], North Carolina" (original citation). Holotype [by monotypy] (♂) in USNM [# 47357]. Synonymy established by Ball (1959: 130). Distribution. This subspecies ranges from "Maine" (Larochelle and Lariviere 1990a: 32) to west-central New York, south to northern Florida (Ball 1959: 131-132), west to eastern Texas (Sabine County, Brian Raber pers. comm. 2010). Records. USA : AL, CT, DC, DE, FL, GA, MA, MD, ME, MS, NC, NH, NJ, NY, PA, RI, SC, TX, VA, VT, WV Note. Ball (1959: 132) reported the presence of intergrade populations of this and the sinuatus forms in Mississippi, Alabama, northern Florida, Georgia, South Carolina, and North Carolina. For practical reasons, these populations are considered to belong to the nominotypical subspecies.
