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 View Figs 3-8 ); elytra (at suture) about as long as pronotum and 1/4 wider than maximum width of pronotum ( Fig. 7 View Figs 3-8 ); abdomen at base slightly narrower than elytra ( Fig. 7 View Figs 3-8 ); antennal articles 4-6 subquadrate to moderately elongate, articles 7-9 slightly transverse ( Figs 25 a, b View Figs 21-38 ); median lobe of aedeagus with apex narrowly produced with sinuate margins in lateral view ( Fig. 75 View Figs 75-82 ); spermatheca with capsule funnel-shaped and cylindrical ( Fig. 80 View Figs 75-82 ); stem curved and slightly swollen basally ( Fig. 80 View Figs 75-82 ); male tergite 8 with four apical dents ( Fig. 78 View Figs 75-82 ).
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 View Figs 3-8 ); 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 View Figs 21-38 ); head and pronotum of about the same width ( Fig. 7 View Figs 3-8 ); elytra and abdomen wider than either head or pronotum; elytra small and short ( Fig. 7 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 1/4 broader than maximum width of pronotum ( Fig. 7 View Figs 3-8 ), pubescence directed obliquely postero-laterad, wavy pattern occurs on each side of disc; abdomen subparallel, slightly narrower than elytra at base ( Fig. 7 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, with four apical dents ( Fig. 78 View Figs 75-82 ). Sternite 8 transverse and slightly produced posteriorly ( Fig. 79 View Figs 75-82 ). Median lobe of aedeagus with narrowly produced apical part of tubus in lateral view ( Fig. 75 View Figs 75-82 ); bulbus enlarged without pronounced two anterior projections in dorsal view ( Fig. 76 View Figs 75-82 ); internal sac with structures as illustrated ( Figs 75, 76 View Figs 75-82 ). Female. Tergite 8 truncate apically ( Fig. 81 View Figs 75-82 ). Sternite 8 broadly rounded posteriorly and bearing median emargination ( Fig. 82 View Figs 75-82 ). Spermatheca with capsule funnel-shaped and cylindrical ( Fig. 80 View Figs 75-82 ); stem curved and swollen basally ( Fig. 80 View Figs 75-82 ).
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].
