Agonum gratiosum (Mannerheim, 1853)

Platynus ruficornis LeConte, 1850: 205. Type locality: Lake Superior (inferred from title of the paper), herein restricted to Marquette, Marquette County, Michigan (see Hubbard and Schwarz 1878: 628). Three syntypes in MCZ [# 5784]. Note. This name has been considered a junior secondary homonym of Agonum ruficorne (Goeze, 1777). As stated before (see “Note” section for Paranchus albipes (Fabricius)), Goeze’s name is based on a misidentification and has no nomenclatural status. Therefore, Platynus ruficornis LeConte is not a homonym and should be used as the valid name for this taxon. However, the name Agonum gratiosum is well established for this common species since the 1960s and I believe it should be preserved. The case should be submitted to the Commission for a ruling. Reversal of precedence (ICZN 1999: 23.9) cannot be used here since LeConte’s name has been used as valid after 1899 (e.g., Blatchley 1910: 135).

Anchomenus gratiosus Mannerheim, 1853: 142. Type locality: "insula Kadjak [Alaska]" (original citation). Lectotype (♀), designated by Lindroth (1955c: 7), in ZMH. Synonymy established by LeConte (1879b: 58), confirmed by Lindroth (1954b: 139).

Europhilus symmetricus Casey, 1920: 129. Type locality: «Devil’s Lake [Ramsey County], N[orth] Dakota" (original citation for the lectotype). Lectotype (♀), designated by Lindroth (1975: 126), in USNM [# 47528]. Synonymy established by Hatch (1953: 145), confirmed by Lindroth (1954b: 140).

Europhilus properans Casey, 1920: 129. Type locality: "Durham [Strafford County], New Hampshire" (original citation). Lectotype (♀), designated by Lindroth (1975: 126), in USNM [# 47530]. Synonymy established by Lindroth (1954b: 140).

Europhilus antiquus Notman, 1922b: 102. Type locality: "Lyme [New London County], C[onnecticu]t" (original citation). Holotype (♂) in USNM [# 26591]. Synonymy established by Lindroth (1954b: 140).

Europhilus carri Casey, 1924: 85. Type locality: "Edmonton [Alberta]" (original citation). Lectotype (♂), designated by Lindroth (1966: 577), in USNM [# 47529]. Synonymy established with doubt by Lindroth (1955c: 7), confirmed by Lindroth (1966: 577). Etymology. The specific name was proposed in honor of Frederick Stephens Carr [1881-1934], teacher and inspector in the educational system in Alberta and amateur coleopterist. His collection, which consisted at the time of his death of about 6,500 North American species, was deposited at the University of Alberta.

Distribution.

This widely distributed species ranges from western Newfoundland (Lindroth 1955a: 128) to Kodiak Island, north to the Anderson River delta in northern Northwest Territories (Lindroth 1966: 578), south to the Sierra Nevada in Califo rnia (El Dorado County, CAS), San Miguel County in New Mexico (Fall and Cockerell 1907: 159, as Platynus ruficornis ), northeastern Kansas (Popenoe 1878: 78, as Platynus ruficornis ), northern Illinois (Lake County, CNC), and northern West Virginia (Tucker and Randolph Counties, CMNH). The species is also known from the Far East (Bousquet 2003c: 453).
