Philhygra subpolaris (Fenyes) Figs 21-26

Brundinia subpolaris Fenyes 1909: 423.

Diagnosis.

This species may be distinguished from other Canadian Philhygra by its small subparallel body (length 2.8-3.2 mm), colour dark brown with reddish or yellowish elytra and darker scutellar section, subquadrate pronotum, elytra slightly longer than pronotum, antennal articles V-X subquadrate to slightly elongate (Fig. 21), and distinctive genital structures and terminalia (Figs 22-26).

Distribution.

Natural history.

In Alberta, adults were caught in window traps attached to aspen snags in a boreal aspen stand harvested two years previously, and in pitfall traps deployed in canola fields. Adults were collected in July.

Comments.

It is the first record of this species in Canada, and its broader distribution in Canada is unknown. It is probably continuously distributed in the Rocky Mountains, from Arizona in the south to Canada in the north.
