Etymology.

Named after Canada, the country of origin, and to commemorate the 150th anniversary of Canada.

Description.

Body length 2.0-3.0 mm, subparallel, yellowish brown with slightly darker head, moderately glossy, forebody with fine and dense pubescence, punctation fine; head subquadrate, eyes moderately large and shorter than postocular region of head, posterior angles rounded and slightly angular, pubescence directed straight and obliquely anteriad; antennomeres V-X strongly transverse, head slightly broader than pronotum; pronotum slightly transverse, posterior angles angular; elytra elongate, at suture longer than pronotum, and about one sixth wider than pronotum, abdomen subparallel, with first four visible tergites deeply impressed basally, males lacking tubercles on first and fifth visible tergites. MALE. Median lobe of aedeagus with tubus strongly produced ventrally, its venter sinuate with apex turned slightly upward, internal sac with complex structures as illustrated (Fig. 10); tergite VIII truncate apically (Fig. 11); sternite VIII truncate and broadly arcuate apically (Fig. 12). FEMALE. Spermatheca S-shaped, capsule spherical, slightly arched with a narrow apical tubular multiple micro-coiled projection, stem sinuate, S-shaped (Fig. 15); tergite VIII truncate apically (Fig. 13); sternite VIII rounded apically (Fig. 14).

Distribution.

Known only from New Brunswick, Canada.

Collection and habitat data.

The holotype and three paratypes were captured on a partially shaded cobblestone bar near the outflow of brook along the Jacquet River. The adults were found under cobblestones and gravel in sand. One paratype was found along a river margin under a cobblestone among grasses away from the water’s edge. Adults were collected in May and June.

Comments.

This species clearly belongs to a different species group than A. fusciceps  , which has capsule of spermatheca entirely tubular.
