Large species; body brown to black (Fig. 10F). Head black, transverse, with eyes medium sized (EyL/ TL = 1.72–1.89 (1.82)), microsculpture of transverse waves, with two interocular punctures between anterior frontal punctures (Fig. 6G); antennae and palpi reddish with basal three antennomeres clearly pale, all antennomeres elongate. Thorax: pronotum brown to black, slightly wider than long, clearly wider than head, with microsculpture of transverse waves, three punctures in dorsal row and one to two in sublateral row with its posteriormost puncture reaching almost to level of second puncture of dorsal row; scutellum sparsely punctured and pubescent; elytra most often pale orange to reddish brown, rarely fully darkened, clearly wider than long, of similar length as pronotum, with rather short uniform pubescence, with punctures clearly separated from each other; legs reddish with inner face of tibia darkened and tarsi paler. Addomen brown to black, tergites uniformly punctured, without clear iridescence. Male. Aedeagus (Figs 16A, 17): paramere rather broad, with slight basal attenuation and extending into softly rounded apex, reaching to the apex of median lobe, with small sensory peg setae forming two broad irregular rows near the edge of the of the paramere, except at very apex which is slightly folded; median lobe continuously slimming toward pointed apex, on parameral side with two folded teeth which almost meet to form a cavity with a small slit towards apex; internal sac with elongate and internal sclerites. Differential diagnosis. Quedius labradorensis can be distinguished from Q. laticollis and Q. molochinus by the presence of two additional setiferous punctures between the anterior frontal punctures. It can be distinguished from other members of the molochinoides -group (Q. lanei, Q. molochinoides, and Q. horni) by the larger body size and pale basal three antennomeres. Synonymic notes. The subspecies Q. l. kodiakensis was described as a form restricted to Kodiak Island, which differs from the nominotypical subspecies by a slightly larger body and more spatulate paramere with larger peg setae (Sආൾඍൺඇൺ 1971a). Generally, species of Quedius s. str. display some variation in body size and shape of the paramere. With more material available, the observed variation between the putative subspecies falls within the variation observed in the widely distributed nominal subspecies. Thus, we consider Quedius l. kodiakensis Smetana, 1999 syn. nov. a junior subjective synonym of Quedius labradorensis Smetana, 1965. Bionomics. As a northern species, Q. labradorensis prefers wet boggy habitats with specimens collected in litter and moss of mixed forests, mainly poplar and birch, in Ontario (Sආൾඍൺඇൺ 1971a), in deep moss in Saskatchewan (Sආൾ-ඍൺඇൺ 1990), fern bogs in Nova Scotia, margins of creeks on Kodiak Island (Sආൾඍൺඇൺ 1971a), and shrubby alpine tundra in Alaska. Sආൾඍൺඇൺ (1976a) reported this species from moss, mushrooms, and deciduous leaf litter (birch and poplar stands) near streams. In the Alberta foothills forests, Q. labradorensis is considered to be an open-ground specialist after forest logging, which only spread short distances into adjacent pristine forests, with numbers of this species also increased after logging (PඈHඅ et al. 2007). In New Brunswick, most adults have been found from April to May in old-growth eastern white cedar swamps in moss usually near small streams, with the exception
