Materials Examined
HOLOTYPE (male):CANADA,Alberta,KananaskisF.E.S.,[51°04'34"N,115°07'46"W] 1.VIII.1971, J.M. and B.A. Campbell, CNC No. 23678 (CNC). Material examined Paratypes are listed in Appendix A.
Etymology
Etymology This species is named after the late Gustav Adolf Lohse (Hamburg, Germany), who discovered it in CNC material.
Diagnosis
Diagnosis This species can be recognized by the following combination of characters: body length 2.7-3.0 mm (Fig. 11); elytra at suture slightly longer than pronotum and at least 1/3 wider than maximum width of pronotum (Fig. 11); abdomen at base about as wide as elytra and subparallel or slightly swollen medially (Fig. 11); antennal articles 5-7 subquadrate, 8-10 slightly transverse (Figs 29 a, b); median lobe of aedeagus with apical part broadly triangular and edges sinuate in lateral view (Fig. 108); spermatheca S-shaped, capsule mushroom-shaped (Fig. 114); stem more or less sinuate and slightly swollen basally (Fig. 114); male tergite 8 truncate apically and with two minute lateral dents at apical margin (Fig. 112). 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).
Description
Description Body length 2.7-3.0 mm; uniformly dark brown to black, sometimes central part of elytra and tarsi rust brown (Fig. 11); 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); head and pronotum of about the same width (Fig. 11); 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); abdomen subparallel, almost as broad as elytra at base (Fig. 11); 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). Sternite 8 as broad as long and truncate apically (Fig. 113). Median lobe of aedeagus with triangularly produced apical part of tubus and edges sinuate in lateral view (Fig. 108); bulbus moderately enlarged with two anterior projections in dorsal view (Figs 109, 110); internal sac with structures as illustrated (Figs 109, 110). Female. Tergite 8 truncate apically (Fig. 115). Sternite 8 broadly rounded posteriorly (Fig. 116). Spermatheca with capsule mushroom-shaped, elongate (Fig. 114); stem sinuate and slightly swollen basally (Fig. 114).
Distribution
Distribution (Fig. 198) Gnypeta lohsei is a Nearctic species known from Alberta, British Columbia, and Alaska and Washington state, United States.
Biology and Ecology
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.
Discussion
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].
