Distribution.

Holarctic. Recorded from across the Palaearctic region, from Western Europe to the Russian Far East ( Klausnitzer 2006). In North America, apparently previously known only from Alaska (Kalsin Bay, Kodiak ( Nyholm 1972)). This record was overlooked by Bousquet et al. (2013).

Canadian records.

British Columbia: Smithers, 28-Jul-2014 to 05-Aug-2014 (4 exx, CBG). Alberta: Jasper National Park, 02-Aug-2010 to 05-Aug-2010 (1 ex, CBG). Manitoba: Churchill, 05-Aug-2005 (1 ex, CBG); Churchill, 18-Aug-2006 (1 ex, JBWM); Churchill, 21-Jul-2007 (2 exx, CBG); Riding Mountain National Park, 16-Jul-2012 to 23-Jul-2012 (1 ex, CBG).

Diagnostic information

(based on Nyholm 1972 and Lohse 1979). Body length 2.7-3.2 mm. Reddish or yellowish brown, head usually darker than pronotum and elytra. Head and pronotum with dense, coarse, granulate punctation. Elytra densely punctate. Male sternite IX and accessory sclerite as in Fig. 23C . Aedeagus as in Fig. 23A, B .

Bionomic notes.

This species is known from acidic Sphagnum bogs ( Nyholm 1972). Most Canadian specimens were collected with Malaise traps; also collected with light traps and by sweep netting.

Comments.

Contacyphon kongsbergensis is morphologically most reliably identified by its genitalia. The lack of a modern revision of North American Contacyphon prevents detailed comparison with related species.
