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).
