Material examined Specimens are listed in Appendix A. Diagnosis 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. Description 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. Male. 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). Female. 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). Distribution (Fig. 196) Gnypeta uteana 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. Collection and habitat data Adults from Alberta were collected in July and August, some from altitudes up to 2040 m.
