description: 11. <i>Gnypeta manitobae</i> Casey (Figs 13, 31 a, b, 125-129) <i>Gnypeta manitobae</i> Casey 1906: 196. As synonym of <i>G. bockiana</i> Casey: Moore and Legner 1975: 421. Synonymy confirmed here as not valid. <b>LECTOTYPE</b> (female): CANADA: Manitoba, Winnipeg; Hanham; Type USNM 38864; <i>manitobae</i> Csy. [handwritten by Casey]; Casey bequest 1925; lectotype designation label by Lohse 1988 [designation not published] (USNM). Present designation. Examined. <b>Material examined</b> The lectotype only. <b>Diagnosis</b> (based on female) This species is known from a single female and is similar to <i>G. crebrepunctata</i>. The two species have a very similar shape of the spermatheca and terminal segments and can be distinguished only by the differences in external morphology and the different geographic ranges. <i>Gnypeta manitobae</i>, in comparison with <i>G. crebrepunctata</i>, has a more transverse pronotum (Fig. 13), and the base of the abdomen is as broad as the elytra (Fig. 13). From other Nearctic <i>Gnypeta</i> species, it can be distinguished by the following combination of characters: body subparallel (Fig. 13), length 2.6 mm; elytra at suture as long as pronotum and at least 1/4 wider than maximum width of pronotum (Fig. 13); abdomen subparallel and at base about as broad as elytra (Fig. 13); antennal articles 4-7 strongly elongate, 8-10 quadrate to slightly transverse (Fig. 31 b). Spermatheca C-shaped with capsule tubular (Figs 127-129). <b>Description</b> Body length 2.6 mm; uniformly dark brown with two basal antennal articles and tarsi rust brown (Fig. 13); integument moderately glossy; pubescence yellowish grey and moderately long and dense; antennal articles 4-7 strongly elongate, 8-10 quadrate to slightly transverse (Fig. 31 b); head and pronotum of about the same width (Fig. 13); 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 about as long as pronotum and about 1/4 wider than maximum width of pronotum, pubescence directed obliquely postero-laterad, in wavy pattern medially on each side of disc (Fig. 13); abdomen subparallel, at base about as broad as elytra (Fig. 13); metatarsus with basal article slightly longer than second, and the third one slightly shorter than second. <b>Male</b>. Unknown. <b>Female</b>. Tergite 8 truncate apically (Fig. 125). Sternite 8 broadly rounded apically with shallow median emargination (Fig. 126). Spermatheca C-shaped, capsule tubular and short (Figs 127-129); stem short and broadly tubular (Fig. 127). Spermatheca is similar to that of <i>G. crebrepunctata</i>. <b>Distribution</b> <i>Gnypeta manitobae</i> is known only from a single type specimen captured in Winnipeg, Manitoba (Casey 1906). <b>Collection and habitat data</b> No data available. <b>Comments</b> Casey (1906) in the original description of <i>G. manitobae</i> mentioned a male specimen from Winnipeg, Manitoba, but did not clearly specify how many specimens he had studied. There is only one specimen in the Casey collection from that locality under <i>G. manitobae</i> and it is a female, which was probably misidentified by Casey as a male. Casey did not designate the holotype in his original description and therefore we designated the only syntype female from Winnipeg as the lectotype.
