Diagnosis

This species can be recognized by the following combination of characters: body robust, length 3.2-3.7 mm ( Fig. 8 View Figs 3-8 ); elytra (at suture) about as long as pronotum and 1/5 wider than maximum width of pronotum ( Fig. 8 View Figs 3-8 ); abdomen at base as broad as elytra and slightly broadening posteriorly ( Fig. 8 View Figs 3-8 ); antennal article 4 subquadrate or slightly elongate, 3-6 slightly to strongly transverse, 7-9 strongly transverse ( Figs 26 a, b View Figs 21-38 ); median lobe of aedeagus with apical part narrowly produced and sinuate laterally ( Fig. 83 View Figs 83-90 ), bulbus in dorsal view with broad lateral swells ( Fig. 84 View Figs 83-90 ); spermatheca with capsule longer than wide, funnel-shaped, lateral sides subparallel ( Fig. 88 View Figs 83-90 ); stem curved, sinuate apically and slightly swollen basally ( Fig. 88 View Figs 83-90 ); male tergite 8 strongly transverse and truncate apically ( Fig. 86 View Figs 83-90 ).

Description

Body length 3.2-3.7 mm; uniformly dark brown to black ( Fig. 8 View Figs 3-8 ); 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 View Figs 21-38 ); head and pronotum of about the same width ( Fig. 8 View Figs 3-8 ); elytra and abdomen wider than either head or pronotum; elytra small and short ( Fig. 8 View Figs 3-8 ); 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 View Figs 3-8 ), pubescence directed obliquely postero-laterad,

in wavy pattern medially on each side; abdomen swollen medially, as broad as elytra at base ( Fig. 8 View Figs 3-8 ); 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 View Figs 83-90 ). Sternite 8 elongate and slightly produced posteriorly ( Fig. 87 View Figs 83-90 ). Median lobe of aedeagus with narrowly produced and sinuate apical part of tubus in lateral view ( Fig. 83 View Figs 83-90 ), sides swollen in dorsal view; bulbus moderately large ( Fig. 84 View Figs 83-90 ); internal sac with structures as illustrated ( Figs 83, 84 View Figs 83-90 ). Female. Tergite 8 truncate apically ( Fig. 89 View Figs 83-90 ). Sternite 8 broadly rounded posteriorly ( Fig. 90 View Figs 83-90 ). Spermatheca with capsule elongate, funnel-shaped with sides subparallel ( Fig. 88 View Figs 83-90 ); stem curved, sinuate apically and swollen basally ( Fig. 88 View Figs 83-90 ).

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].
