Holotype (male): USA, Alaska, King Salmon, Naknek R. Alaska, 6.VII.1952, W.R. Mason, No. 20313 (CNC). Examined. New locality data. CANADA: Yukon Territory: location EMAN Plot, Cadet Camp, EP-Yukon, 15.X.2001 (1 ♀, NoFC); Tombstone Mts., 64.60560°, 138.36413°, Rep. 1, mesic, yellow pan trap, 21-24.VI.2011, NBP Field Party (1 ♀, LFC). USA: Alaska: Quinhagak site G, 3 m elevation, 59.71035°, 161.89102°, dry tundra, between Rubus sp. hummocks, pitfall, 18-26, VIII.2014, V. Forbes (1 ♂, LFC) [submitted for barcoding]; Naknek, 58.73973°N - 157.0636°W , 2-5 m elev., creekside/ocean beach confluence, under boards and driftwood 10.VI.2007, D.S. Sikes. UAM:Ento:29798 (1 ♂, UAM) [DNA barcoded: http://arctos.database.museum/guid/UAM:Ento:29798]. Diagnosis. This species may be distinguished by the following combination of characters: body broadly subparallel, dark brown, with elytra, tarsi and tibiae often reddish-brown (Fig. 50) (one specimen from northern Yukon was entirely black); length 2.8-3.3 mm; integument of forebody with moderately pronounced meshed microsculpture ; head about one-eighth narrower than maximum width of pronotum (Fig. 50); pronotum transverse, about evenly wide in basal one-third of its length, then strongly broadest at apical one-third and gradually narrowed apically (Fig. 50); elytra at suture about as long as pronotum, its surface coarsely granulose (Fig. 50); basal two articles of metatarsus about the same length, each shorter than fifth article. Male. Apical margin of tergite VIII with short, very obtusely angular projection in medial two-thirds with rounded lateral angles, margin of projection smooth or micro-denticulate (Fig. 53); apical margin of sternite VIII broadly parabolic (Fig. 54); median lobe of aedeagus with tubus broadly arched, bent ventrad, apex narrow and rounded (Fig. 52). Female. Apical margin of tergite VIII truncate in middle one-third (Fig. 55); apical margin of sternite VIII arcuate, antecostal suture distinctly sinuate (Fig. 56); spermatheca highly sinuate as illustrated (Fig. 57). Natural history. Adults were captured in June, July, August, and October. One Alaskan specimen was captured in tundra between Rubus species and another at a creekside/ocean beach confluence, under boards and driftwood. Distribution. Canada: YT. USA: AK ( Lohse et al. 1990 , Klimaszewski et al. 2008 , Klimaszewski et al. 2012 ). Comments. Only a few specimens of this species are known. Its distribution is nordic and the habitat is unknown. One specimen (UAM:Ento:29798) in UAM was DNA barcoded (UAMIC2693-15), the first and only for this species so far.
