Agaricomorpha vincenti Klimaszewski & Webster Figs 27-33

Agaricomorpha vincenti Klimaszewski & Webster (2016).

Diagnosis.

This species is distinguishable by its small body that is compact and narrowly oval in outline (Fig. 27); length 1.7-1.9 mm; uniformly black; forebody with strong microsculpture, that on elytra and abdomen forming scale-like structures, punctation coarse, sparse and flatly impressed, pubescence sparse and approximately evenly distributed on forebody (Fig. 27).

Agaricomorpha vincenti may be readily distinguished from Agaricomorpha websteri Klimaszewski & Brunke by the differently shaped pronotum, which is much broader than the elytra (Fig. 27), by its uniformly black body, and by the shape of median lobe of aedeagus (Fig. 28), male tergite VIII (Fig. 29), and spermatheca (Fig. 33).

Distribution.

Natural history.

In New Brunswick, specimens of Agaricomorpha vincenti were captured in Lindgren funnel traps in a rich Appalachian hardwood forest, a Populus tremuloides stand with a few conifers, an old-growth northern hardwood forest, and a hardwood forest on an island in a river. In Alberta, adults were captured in window traps attached to aspen snags in a boreal aspen stand harvested two years previously. Adults were collected during May, June, and July in New Brunswick, and in May, August and September in Alberta.

Comments.

This species is probably continuously distributed from New Brunswick to Alberta and likely extends further to Alaska.
