Description Body length 3.2-3.7 mm; uniformly dark brown to black (Fig. 8); integument moderately glossy; pubescence yellowish grey and moderately long and dense; antennal article 4 subquadrate or slightly elongate, 5-6 slightly and 7-9 strongly transverse (Figs 26 a, b); head and pronotum of about the same width (Fig. 8); elytra and abdomen wider than either head or pronotum; elytra small and short (Fig. 8); head rounded basally; pronotum broadest in apical third, pubescence directed anterad along midline and laterad elsewhere; elytra (at suture) about as long as pronotum and 1/5 broader than maximum width of pronotum (Fig. 8), pubescence directed obliquely postero-laterad, in wavy pattern medially on each side; abdomen swollen medially, as broad as elytra at base (Fig. 8); metatarsus with two basal articles of about the same length and the third one slightly shorter. Male. Tergite 8 transverse and truncate apically and slightly concave medially (Fig. 86). Sternite 8 elongate and slightly produced posteriorly (Fig. 87). Median lobe of aedeagus with narrowly produced and sinuate apical part of tubus in lateral view (Fig. 83), sides swollen in dorsal view; bulbus moderately large (Fig. 84); internal sac with structures as illustrated (Figs 83, 84).

Distribution (Fig. 195) Gnypeta groenlandica is a Nearctic species recorded here from Greenland, and newly in Canada (Manitoba, Nunavut, Yukon Territory), and the United States (Alaska). Collection and habitat data Adults were collected in June, July and August, mainly in alpine habitats from Salix litter, litter on shore of a lagoon, and in crown of Ross’s Avens (Geum rossii), rose family (Rosaceae). Comments The late Steve Ashe (University of Kansas) worked on a revision of Nearctic Gnypeta, but was not able to complete it. Some CNC specimens of this species bear his identification labels as G. praeminosa Ashe, 1987 [manuscript – unpublished name].
