Philhygra finitima (Casey, 1910) Fig. 32A-H

Material

(non-sequenced specimens). Canada: Ontario: Algonquin Park , ~ 45.87, -77.33, car net, 20.VII.2016, T. Struyve (10, CNC, LFC [4 males, 6 females])

Distribution.

Origin. Nearctic. Canada: ON [new record]. United States: MA, RI.

Diagnosis.

This species can be readily recognized by a combination of its small size, large eyes and relatively simple, ventrally projecting median lobe of the aedeagus in lateral view (Fig. 32B ).

Bionomics.

Nothing specific is known about this species’ microhabitat preferences but it probably occurs near water as do other species of the genus. The series of Ontario specimens was collected using a car net, which is typically effective for collecting small staphylinids.

Comments.

Philhygra finitima is a native Nearctic species distributed in northeastern North America. Here, we newly report it from Canada. Canadian specimens were identified based on comparison with images (Fig. 32C ) of the unpublished lectotype of P. finitima in the Casey collection at NMNH.
