Natural history
All specimens of Dinaraea subdepressa from NB were captured in Lindgren funnel traps in the following forest types: an old jack pine forest, a red pine forest, an old-growth eastern white cedar forest, an old black spruce forest, mixed forests, a red oak forest, and an old balsam poplar forest near a river. Little is known about the biology and microhabitat requirements of this species. Other members of the genus live in subcortical habitats and may play a role as natural enemies of bark beetles and other subcortical insects (Klimaszewski et al. 2013b[1]). This species presumably has a similar biology.
Distribution in Canada and Alaska
NB (New Canadian record).
Comments
Dinarea subdepressa (Bernhauer) was previously known only from NH in the USA (Bernhauer 1907[2]). Females were previously unknown and are illustrated for the first time in this publication (Figs 196–198). This species is externally very similar to Dinaraea curtipenis Klimaszewski & Webster but differs in having the posterolateral angles of the pronotum very sharp, with the margin strongly depressed from the angle to the middle of the base, forming a groove (Fig. 192). In Dinaraea curtipenis, the posterior angle is rounded and the margin is not strongly depressed (Fig. 178).
