Type material.

Types not examined.

Diagnosis.

Males have a distinctive, asymmetrical aedeagus that differs from all other Nearctic species (Fig. 39C ). Females can be distinguished by the shape of their valvifers (Fig. 39A ).

Description.

Body length 8 mm; body coloration dark, appendages and mouthparts light red, elytra bicolored with narrow black base, or monochromatic black. Gular sutures parallel; antennomeres V-VII longer than wide. Wing dimorphic, elytra as long or slightly longer than pronotum. Females tergite IX with paraprocts undivided, apical lobes shorter than basal portion in dorsal view; sternite VIII oblong, valvifers and coxites divided (Fig. 39A ). Male sternite VIII without patches of dark setae, apical emargination shallow and round (Fig. 39 B ). Ventral process of aedeagus asymmetrical in ventral view (Fig. 39C ; Assing and Schülke 2012).

Distribution.

Canada: AB, BC, NB, NF, QC ( Bousquet et al. 2013).

Remarks.

Native to the Palearctic and adventive in North America. Common in unforested habitats ( Assing and Schülke 2012).
