Abstract

Twelve species of the genus Dinaraea Thomson are recognized in the Nearctic region, ten of which occur in Canada, all east of the Rocky Mountains. Six species are herein described as new to science: D. bicornis Klimaszewski & Webster, sp. n.; D. curtipenis Klimaszewski & Webster, sp. n.; D. longipenis Klimaszewski & Webster, sp. n.; D. quadricornis Klimaszewski & Webster, sp. n.; D. worki Klimaszewski & Jacobs, sp. n.; and D. piceana Klimaszewski & Jacobs, sp. n. Four formerly described species are confirmed in Canada: D. angustula (Thomson), D. backusensis Klimaszewski & Brunke, D. borealis Lohse, and D. pacei Klimaszewki & Langor. The previously unknown male of D. borealis Lohse and female of D. backusensis are described. All species are illustrated with colour habitus images and black and white images of the median lobe of the aedeagus and spermatheca, and tergite VIII and sternite VIII of both sexes. New habitat and distribution data are presented and a key to all Nearctic species of the genus is provided.
