Platynus mannerheimii (Dejean, 1828)

It is worth drawing attention to the records of Platynus mannerheimii published by Bertrand ( 2005) who collected 89 specimens of this species in the Black Brook district of northwestern New Brunswick. Although this Holarctic species was not recorded from New Brunswick by Bousquet ( 1991), Bousquet & Larochelle ( 1993) or Goulet & Bousquet ( 2004), Bertrand failed to note that this species was a new record for New Brunswick. It is found in coniferous forests, thickets bordering lakes, ponds and slow rivers, Sphagnum bogs, open Carex marshes, open sub-alpine scrubland, and moist alpine meadows, on open or shaded wet soil; adults feed on Coleoptera larvae ( Larochelle & Larivière 2003).
