Diagnosis.

Body length 2.8-3.2 mm, narrowly subparallel with head slightly narrower than pronotum; body colour dark brown, and with tibiae, tarsi and often basal antennal articles reddish-brown; forebody with dense microsculpture, and moderately dense punctation and pubescence, and strongly glossy; head round and slightly narrower than pronotum; pronotum slightly transverse, with sides rounded, and as wide as elytra; elytra at suture about as long as pronotum or slightly longer (Fig. 7a); abdomen subparallel, as wide as elytra and with basal impressions on first three visible tergites; antennal articles V-X slightly transverse (Fig. 7a). MALE [description of male is based on poorly preserved specimen and should be consider as tentative]: male tergite VIII truncate apically (Fig. 7c); sternite VIII rounded apically and slightly produced medially (Fig. 7d); median lobe of aedeagus with tubus straight and with complex structures of internal sac (Fig. 7b). FEMALE: tergite VIII truncate apically with sharp lateral angles (Fig. 7f); sternite VIII rounded apically (Fig. 7g); spermatheca with narrowly elongate sac-shaped capsule connected with L-shaped neck and narrow and long stem slightly sinuate posteriorly at apex (Fig. 7e).

Distribution.

This native Nearctic species is here described from Nova Scotia, New Brunswick, and Quebec (Map 5).

Bionomics.

Adults were collected from May to July in Lindgren traps in an old-growth eastern hemlock stand, an old hardwood stand, and in a sugar maple forest and a red spruce forest.

Etymology.

This species is named after Odell Park in Fredericton, New Brunswick, where the holotype was found. This park was originally the estate of Reverend Jonathan Odell whom the park was named after. This park was established in 1954.
