Material examined Paratypes are listed in Appendix A.

Etymology

This species is named after the late Gustav Adolf Lohse (Hamburg, Germany), who discovered it in CNC material.

Diagnosis

This species can be recognized by the following combination of characters: body length 2.7-3.0 mm ( Fig. 11 View Figs 9-14 ); elytra at suture slightly longer than pronotum and at least 1/3 wider than maximum width of pronotum ( Fig. 11 View Figs 9-14 ); abdomen at base about as wide as elytra and subparallel or slightly swollen medially ( Fig. 11 View Figs 9-14 ); antennal articles 5-7 subquadrate, 8-10 slightly transverse ( Figs 29 a, b View Figs 21-38 ); median lobe of aedeagus with apical part broadly triangular and edges sinuate in lateral view ( Fig. 108 View Figs 108-116 ); spermatheca S-shaped, capsule mushroom-shaped ( Fig. 114 View Figs 108-116 ); stem more or less sinuate and slightly swollen basally ( Fig. 114 View Figs 108-116 ); male tergite 8 truncate apically and with two minute lateral dents at apical margin ( Fig. 112 View Figs 108-116 ). Gnypeta lohsei is readily distinguishable from G. caerulea by smaller, robust and less glossy body and subquadrate antennal articles 5-7 ( Figs 29 a, b View Figs 21-38 ).

Description

Body length 2.7-3.0 mm; uniformly dark brown to black, sometimes central part of elytra and tarsi rust brown ( Fig. 11 View Figs 9-14 ); integument moderately glossy; pubescence yellowish grey and moderately long and dense; antennal article 4 moderately elongate, 5-7 subquadrate, 8-10 slightly transverse ( Figs 29 a, b View Figs 21-38 ); head and pronotum of about the same width ( Fig. 11 View Figs 9-14 ); elytra and abdomen wider than either head or pronotum; head rounded posteriorly; pronotum broadest in apical third, pubescence directed anterad along midline and laterad elsewhere; elytra at suture slightly longer than pronotum and about 1/3 wider than maximum width of pronotum, pubescence directed obliquely postero-laterad, in wavy pattern on medial parts of disc ( Fig. 11 View Figs 9-14 ); abdomen subparallel, almost as broad as elytra at base ( Fig. 11 View Figs 9-14 ); metatarsus with two basal articles of about the same length and the third one slightly shorter. Male. Tergite 8 transverse and truncate apically with two minute apical dents ( Fig. 112 View Figs 108-116 ). Sternite 8 as broad as long and truncate apically ( Fig. 113 View Figs 108-116 ). Median lobe of aedeagus with triangularly produced apical part of tubus and edges sinuate in lateral view ( Fig. 108 View Figs 108-116 ); bulbus moderately enlarged with two anterior projections in dorsal view ( Figs 109, 110 View Figs 108-116 ); internal sac with structures as illustrated ( Figs 109, 110 View Figs 108-116 ). Female. Tergite 8 truncate apically ( Fig. 115 View Figs 108-116 ). Sternite 8 broadly rounded posteriorly ( Fig. 116 View Figs 108-116 ). Spermatheca with capsule mushroom-shaped, elongate ( Fig. 114 View Figs 108-116 ); stem sinuate and slightly swollen basally ( Fig. 114 View Figs 108-116 ).

Distribution (Fig. 198)

Gnypeta lohsei is a Nearctic species known from Alberta, British Columbia, and Alaska and Washington state, United States.

Collection and habitat data

Adults were collected in June, July, and August, from high altitudes of up to 2340 m. No habitat data are available.

Comments

The late Gustav Adolf Lohse (Hamburg, Germany) worked on a revision of Nearctic Gnypeta but was not able to complete it. The CNC specimens of this species he studied bear his identification labels as G. albertae Lohse and G. paracareluea Lohse [manuscript – unpublished names].
