Diagnosis
This species can be recognized by the following combination of characters: body length 3.2-3.6 mm ( Fig. 4 View Figs 3-8 ); elytra (at suture) slightly longer than pronotum and 1/3 wider than maximum width of pronotum ( Fig. 4 View Figs 3-8 ); abdomen at base distinctly narrower than elytra ( Fig. 4 View Figs 3-8 ); antennal articles 4-6 elongate in males and subquadrate in females, articles 7-9 transverse ( Figs 22 a, b View Figs 21-38 ); median lobe of aedeagus with apical part broadly triangular in lateral view ( Fig. 48 View Figs 48-56 ); spermatheca with capsule wider than long and funnel-shaped ( Fig. 54 View Figs 48-56 ); stem sinuate and slightly swollen basally ( Fig. 54 View Figs 48-56 ).
Description
Body length 3.2-3.6 mm; black, sometimes central part of elytra and tarsi reddish brown ( Fig. 4 View Figs 3-8 ); 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 View Figs 21-38 ); 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 View Figs 3-8 ); 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 View Figs 3-8 ), pubescence directed obliquely laterad; abdomen subparallel; metatarsus with two basal articles of about the same length and the third one slightly shorter. Male. Tergite 8 transverse and truncate apically ( Fig. 52 View Figs 48-56 ). Sternite 8 slightly transverse and rounded posteriorly ( Fig. 53 View Figs 48-56 ). Median lobe of aedeagus with broadly triangular apical part of tubus in lateral view ( Fig. 48 View Figs 48-56 ), bulbus enlarged and bearing two small angular anterior projections in dorsal view ( Fig. 49 View Figs 48-56 ), internal sac with structures as illustrated ( Figs 48-50 View Figs 48-56 ). Female. Tergite 8 similar to that of male ( Fig. 55 View Figs 48-56 ). Sternite 8 broadly rounded posteriorly ( Fig. 56 View Figs 48-56 ). Spermatheca with capsule wider than long and funnel-shaped ( Fig. 54 View Figs 48-56 ); stem sinuate and slightly swollen basally ( Fig. 54 View Figs 48-56 ).
Distribution (Fig. 191)
Gnypeta brincki 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.
Collection and habitat data
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.
