This species is dedicated to Amélie Gilbert (LFC), who dissected thousands of specimens of Aleocharinae  for our projects.


Body length 2.2-2.4 mm, narrowly elongate, subparallel, black except tarsi and antennae reddish brown (Fig. 494); integument strongly glossy, moderately punctate and pubescent, pubescence short and adhering to body; head subequal to pronotum in size, pubescence directed outward and posterolaterad from midline of disk; eyes large, slightly shorter than postocular area; antennal articles incrassate and articles V–X moderately to strongly transverse; pronotum trapezoidal in shape, broadest subapically, narrower than elytra, pubescence directed almost straight posteriad; elytra elongate, with distinct narrowly rounded shoulders, pubescence directed straight and obliquely posteriad; abdomen subparallel with three basal tergites deeply impressed basally. Male. Median lobe of aedeagus with tubus long, narrow and curved ventrally (Fig. 495); tergite VIII truncate apically (Fig. 496); sternite VIII with apical margin obtusely triangularly produced in middle one-sixth (Fig. 497). Female. Tergite VIII broadly arcuate apically (Fig. 498); sternite VIIII with apical margin broadly triangularly produced, apex rounded (Fig. 499); spermatheca with capsule spherical, stem forming loose coil in apical half, sinuous and narrower basad (Fig. 500).


This species is known from NB and the NT and is likely transcontinental in Canada.

Natural history.

All adults of Phloeopora gilbertae  from NB were captured in Lindgren funnel traps, most in hardwood forests. Specimens were captured in the canopy of a Populus tremuloides  Michx. (trembling aspen) stand, in the canopy of Populus tremuloides  , Juglans cinerea  L. (butternut) and under Tilia americana  L. (American basswood) in a hardwood forest on an island in a river, in Lindgren traps under Populus balsamifera  L. in a Populus balsamifera  stand near a river, in a red oak stand with Populus  , a hardwood stand, and in a Pinus banksiana  forest. The specimen from the Northwest Territories was collected in a Lindgren funnel trap in a mixed Picea  - Betula  forest. Adults were collected during May, June, July, and August. Other members of this genus live in subcortical habitats ( Klimaszewski et al. 2011, Webster et al. 2012), and we presume this species lives in similar habitats.


This species may be separated from its Nearctic congeners by its body proportions, the uniformly black body color except for the appendages, and by the shape of the median lobe of the aedeagus in lateral view, and the spermatheca. It differs from the other two eastern Canadian species, Phloeopora oregona  Casey and Phloeopora canadensis  Klimaszewski and Langor by the black body (brown with darker head in Phloeopora canadensis  and Phloeopora oregona  ), the elongate rather than transverse elytra, the apical part of the median lobe of the tubus straight in lateral view (strongly produced in the other two species), the spermathecal stem forming a shorter loop, and male tergite VIII with the apex more abruptly produced than that of Phloeopora canadensis  .
