HOLOTYPE (male): CANADA, Northwest Territories, Unnamed Lake, 18 mi NW Inuvik, via East Channel, [= 68°21' N, 133°43' W] 26.VI.1972, A. Smetana, CNC No. 23677 (CNC). PARATYPES: listed in Appendix A.
Etymology
This species is named for distinct dents on male tergite 8.
Diagnosis
This species can be recognized by the following combination of characters: body length 2.5-2.7 mm (Fig. 7); elytra (at suture) about as long as pronotum and 1/4 wider than maximum width of pronotum (Fig. 7); abdomen at base slightly narrower than elytra (Fig. 7); antennal articles 4-6 subquadrate to moderately elongate, articles 7-9 slightly transverse (Figs 25 a, b); median lobe of aedeagus with apex narrowly produced with sinuate margins in lateral view (Fig. 75); spermatheca with capsule funnel-shaped and cylindrical (Fig. 80); stem curved and slightly swollen basally (Fig. 80); male tergite 8 with four apical dents (Fig. 78).
Description
Body length 2.5-2.7 mm; dark brown to black, sometimes central part of elytra and legs or tarsi only reddish brown (Fig. 7); integument moderately strongly glossy; pubescence yellowish grey and moderately long and dense; antennal article 4 slightly shorter than preceding article, articles 4-6 quadrate to moderately elongate, and 7-9 slightly transverse (Figs 25 a, b); head and pronotum of about the same width (Fig. 7); elytra and abdomen wider than either head or pronotum; elytra small and short (Fig. 7); 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 1/4 broader than maximum width of pronotum (Fig. 7), pubescence directed obliquely postero-laterad, wavy pattern occurs on each side of disc; abdomen subparallel, slightly narrower than elytra at base (Fig. 7); metatarsus with two basal articles of about the same length and the third one slightly shorter. Male. Tergite 8 transverse and truncate apically, with four apical dents (Fig. 78). Sternite 8 transverse and slightly produced posteriorly (Fig. 79). Median lobe of aedeagus with narrowly produced apical part of tubus in lateral view (Fig. 75); bulbus enlarged without pronounced two anterior projections in dorsal view (Fig. 76); internal sac with structures as illustrated (Figs 75, 76). Female. Tergite 8 truncate apically (Fig. 81). Sternite 8 broadly rounded posteriorly and bearing median emargination (Fig. 82). Spermatheca with capsule funnel-shaped and cylindrical (Fig. 80); stem curved and swollen basally (Fig. 80).
Distribution (Fig. 194)
Gnypeta dentata is a Nearctic species recorded here from Saskatchewan, Alberta, and Northwest Territories.
Collection and habitat data
Adults were collected in June, July and August; no habitat data available.
Comments
The late Gustav Adolf Lohse (Hamburg, Germany) worked on a revision of Nearctic Gnypeta, but was not able to complete his project. Some CNC specimens of this species bear his identification labels as G. dentata Lohse [manuscript – unpublished name].
