Examined. <b>New synonymy</b>. <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 2.6-2.8 mm (Fig. 14); elytra at suture slightly longer than pronotum and about 1/3 wider than maximum width of pronotum (Fig. 14); abdomen at base distinctly narrower than elytra and subparallel (Fig. 14); antennal article 4 strongly elongate, 5 subquadrate or slightly elongate, 7-10 slightly transverse (Figs 32 a, b); median lobe of aedeagus with apical part moderately broad and produced in lateral view (Fig. 130); spermatheca C-shaped, with broadly tubular and mushroom-shaped capsule (Fig. 136); stem broadly tubular and short (Fig. 136); male tergite 8 truncate apically and with slight apical emargination (Fig. 134); female sternite 8 with strong median apical emargination (Fig. 138). The slim, strongly glossy body, basal article of metatarsus almost as long as the two following articles combined; distinct shape of spermatheca; medially emarginated female sternite 8, and the shape of the apical portion of the median lobe of the aedeagus are the best characters for recognition of this species. <b>Description</b> Body length 2.6-2.8 mm; uniformly dark brown to black, elytra often rust brown medially, and tibiae and/or tarsi rust brown (Fig. 14); integument strongly glossy; pubescence yellowish grey and moderately long and dense; antennal article 4 strongly elongate, 5 subquadrate or slightly elongate, 7-10 slightly transverse (Fig. 32 a, b); head and pronotum of about the same width (Fig. 14); elytra and abdomen (less so) wider than either head or pronotum; head rounded posteriorly; pronotum broadest in apical third, pubescence directed anterad along midline and laterad elsewhere; elytra at suture slightly longer than pronotum and about 1/3 wider than maximum width of pronotum, pubescence directed obliquely postero-laterad, in wavy pattern medially on each side of disc (Fig. 14); abdomen subparallel, distinctly narrower than elytra at base (Fig. 14); metatarsus with basal article strongly elongate and about as long as the two following articles combined. <b>Male</b>. Tergite 8 transverse and truncate apically with slight median emargination (Fig. 134). Sternite 8 elongate and broadly rounded apically (Fig. 135). Median lobe of aedeagus with triangular and moderately broad apical part of tubus in lateral view (Fig. 130); bulbus moderately enlarged in dorsal view (Figs 131, 132); internal sac with structures as illustrated (Figs 130-132). <b>Female</b>. Tergite 8 truncate apically (Fig. 137). Sternite 8 broadly rounded posteriorly with deep median emargination (Fig. 138). Spermatheca with tubular and short, mushroom-shaped capsule (Fig. 136); stem short and broadly tubular (Fig. 136). <b>Distribution</b> (Fig. 196) <i>Gnypeta uteana</i> is a western Nearctic species known from southwestern Utah, Colorado and California (Casey 1906, 1911). We report this species for the first time from the province of Alberta. <b>Collection and habitat data</b> Adults from Alberta were collected in July and August, some from altitudes up to 2040 m. Habitat data not available.
