Holotype not examined. <b>Material examined</b> Specimens are listed in Appendix A. <b>Diagnosis</b> This species can be recognized by the following combination of characters: body length 3.2-3.6 mm (Fig. 4); elytra (at suture) slightly longer than pronotum and 1/3 wider than maximum width of pronotum (Fig. 4); abdomen at base distinctly narrower than elytra (Fig. 4); antennal articles 4-6 elongate in males and subquadrate in females, articles 7-9 transverse (Figs 22 a, b); median lobe of aedeagus with apical part broadly triangular in lateral view (Fig. 48); spermatheca with capsule wider than long and funnel-shaped (Fig. 54); stem sinuate and slightly swollen basally (Fig. 54). <b>Description</b> Body length 3.2-3.6 mm; black, sometimes central part of elytra and tarsi reddish brown (Fig. 4); integument strongly glossy; pubescence yellowish grey and moderately long and dense; antennal article 4 slightly shorter than preceding one, 4-6 elongate in males and subquadrate in females, articles 7-9 transverse (Figs 22 a, b); head and pronotum of about the same width, abdomen wider than either head or pronotum; elytra large and distinctly broader than remainder of body (Fig. 4); head rounded posteriorly; pronotum broadest in apical third, pubescence directed anterad along midline and laterad elsewhere; elytra (at suture) slightly longer than pronotum and 1/3 broader than maximum width of pronotum (Fig. 4), pubescence directed obliquely laterad; abdomen subparallel; metatarsus with two basal articles of about the same length and the third one slightly shorter. <b>Male</b>. Tergite 8 transverse and truncate apically (Fig. 52). Sternite 8 slightly transverse and rounded posteriorly (Fig. 53). Median lobe of aedeagus with broadly triangular apical part of tubus in lateral view (Fig. 48), bulbus enlarged and bearing two small angular anterior projections in dorsal view (Fig. 49), internal sac with structures as illustrated (Figs 48-50). <b>Female</b>. Tergite 8 similar to that of male (Fig. 55). Sternite 8 broadly rounded posteriorly (Fig. 56). Spermatheca with capsule wider than long and funnel-shaped (Fig. 54); stem sinuate and slightly swollen basally (Fig. 54). <b>Distribution</b> (Fig. 191) <i>Gnypeta brincki</i> is a Holarctic species with probably circumpolar distribution. In the Palaearctic region it was recorded from Norway, Sweden and Finland (Palm 1966; Smetana 2004). Here, it is recorded for the first time in North America from Quebec, Yukon Territory, Northwest Territories and Alaska. <b>Collection and habitat data</b> Adults were collected in June, July, and August. The Quebec specimen was found in an estuary of a river, 1-2 m above high tide line in organic mat on sand and gravel. The Yukon and Northwest Territories specimens were captured at altitudes ranging from 1005-1280 m.
