Agonum deplanatum Menetries, 1843

Agonum deplanatum Ménétriés, 1843: 57. Type locality: «Californie» (original citation), herein restricted to Berkeley, Alameda County (see Casey 1924: 82, as Anchomenus amplicollis ). Lectotype (♀), designated by Lindroth (1966: 598), in ZMH.

Platynus fallianus Leng, 1919b: 203. Unnecessary replacement name for Platynus deplanatus ( Ménétriés, 1843).

Anchomenus amplicollis Casey, 1924: 82. Type locality: "Berkeley [Alameda County], California" (original citation). Lectotype (♂), designated by Liebherr (1991a: 116), in USNM [# 47436]. Synonymy established by Liebherr (1991a: 116).

Distribution.

This species is known from southwestern Oregon (Jackson County, CNC) to southern California (Fall 1901a: 46), including the Sierra Nevada (Papp 1978: 163). The record from “Idaho” (Horn 1872c: 385) is probably in error.

Note.

Agonum fallianum Leng has been retained as the valid name for this taxon by most authors since 1919 on the account that Agonum deplanatum Ménétriés was a junior homonym of Agonum deplanatum (Chaudoir). Leng (1919b: 203) believed the date of publication for Ménétriés’ name was 1844 and Chaudoir’s name 1843. However, both names were published in 1843. Ménétriés’ publication was issued on 29 July 1843 as indicated on page 64 of the journal and Chaudoir’s publication was issued after 7 October 1843, the date of permission for publication as indicated on the recto of the title page. The reversal of precedence (ICZN 1999: Article 23.9) cannot be applied in this case because Agonum deplanatum Ménétriés has been used as a valid name after 1899 (e.g., Csiki 1931: 841).
