Types not examined. Diagnosis. This species is most similar to L. fulvipenne but can be distinguished by the ventral process of the aedeagus, which lacks an apical tooth and is nearly symmetrical in ventral view (Fig. 45C ). Description. Body length 8 mm; body coloration dark, appendages light brown, elytra usually bicolored with narrow black base. Gular sutures parallel; antennomeres V-VII longer than wide. Elytra as long as pronotum or slightly shorter. Female tergite IX with apical lobes of paraprocts longer than continuous anterior portion in dorsal view; sternite VIII with truncate apex. Ventral process of the aedeagus strongly deflexed, distal tip lying beyond median foreman in lateral view (Fig. 45C ). Distribution. Canada: ON ( Pentinsaari et al. 2019 ). Remarks. Native to the Palearctic and adventive in North American. Found in forest and riparian habitats ( Pentinsaari et al. 2019 ).
