Comments.

Atomaria lederi Johnson was first reported for North America by Johnson et al. (2007) without supporting data. Majka et al. (2010) provided supporting data for Johnson’s record and additional locality and habitat data from NS for the presence of Atomaria lederi in Canada and North America. This species is widespread in NS and was found mostly in red spruce ( Picea rubens Sarg.) and red spruce-eastern hemlock ( Tsuga canadensis (L.) Carr.) forests ( Majka et al. 2010). New Brunswick speci mens were collected from Lindgren funnel traps in a mixed forest, jack pine ( Pinus banksiana Lamb.) forest, red oak ( Quercus rubra L.) forest, old-growth white spruce ( Picea glauca (Moench) Voss) and balsam fir ( Abies balsamea (L.) Mill.) forest, and a red spruce forest with some red maple ( Acer rubrum L.) and balsam fir. Bousquet et al. (2013) considered the status of Atomaria lederi in North America as uncertain and that the species could either be adventive to North America or Holarctic. Klimaszewski et al. (2015) treated Atomaria lederi as an adventive Palaearctic species. Given that this species was collected in natural habitats throughout NB and NS suggests it could be a Holarctic species that has been undetected in Canada and North America until recently.
