description: 18. <i>Gnypeta minuta</i> Klimaszewski and Webster, sp. nov. urn:lsid:zoobank.org:act: 34D54632-2C6C-426C-8C85-C205C3004FDD (Figs 20, 38 a, b, 181-189, 193) (Figs 20, 38 a, b, 181-189, 193) <b>HOLOTYPE</b> (male): <b>CANADA</b>, New Brunswick, York Co., Douglas, Keswick River at Rt. 105, 45.9943&amp;ring; N., 66.8337&amp;ring; W., 18.06.2004, R. P. Webster coll., silver maple forest, under debris on muddy soil near small pool, IRM No. 2 (LFC). <b>PARATYPE</b> (female): <b>CANADA</b>: New Brunswick, Restigouche Co., Little Tobique River near Red Brook, 47.4465&amp;ring; N., 67.0689&amp;ring; W., 13.06.2006, R. P. Webster coll., river margin, under debris on clay and sand mix (LFC). <b>Etymology</b> The name of this species is the Latin “ <i>minuta</i> ”, meaning small, in reference to the small size of this species. <b>Diagnosis</b> This species can be recognized by the following combination of characters: body length 2.3 mm (Fig. 20); elytra at suture longer than pronotum and about 1/6 wider than maximum width of pronotum (Fig. 20); abdomen at base distinctly narrower than elytra and broadening posteriorly, tergal impressions with coarse punctation (Fig. 20); antennal article 4 strongly elongate, 5-7 moderately elongate, 8-10 subquadrate (Figs 38 a, b); median lobe of aedeagus with apical part broadly triangular in lateral view (Fig. 181); male tergite 8 truncate apically (Fig. 184). The subquadrate antennal articles 7-10, posteriorly broadening abdomen, and distinct shape of the apical portion of the median lobe of the aedeagus, slightly emarginated apex of female sternite 8 and the pipe-shaped spermatheca are the best characters for recognition of this species. <b>Description</b> Body length 2.3 mm; dark brown (Fig. 20); integument moderately glossy; pubescence yellowish grey and moderately short and dense; antennal articles 5-7 moderately elongate, 8-10 subquadrate (Figs 38 a, b); head slightly narrower than pronotum (Fig. 20); elytra and abdomen (less so) wider than either head or pronotum; head rounded posteriorly; pronotum broadest in the apical third, pubescence directed obliquely posterolaterad from the midline; elytra at suture longer than pronotum and about 1/6 wider than maximum width of pronotum, pubescence directed obliquely postero-laterad, in weak wavy pattern medially on each side of disc (Fig. 20); abdomen broadening posteriorly, distinctly narrower than elytra at base (Fig. 20); metatarsus with basal article slightly longer than the following article. <b>Male</b>. Tergite 8 truncate apically (Fig. 184). Sternite 8 elongate and broadly rounded apically (Fig. 185). Median lobe of aedeagus with broadly triangular apex in lateral view (Fig. 181); bulbus moderately large in dorsal view (Fig. 182); internal sac with complex structures as illustrated (Figs 181, 182). <b>Female</b>. Tergite 8 broadly rounded apically (Fig. 188); sternite 8 with shallow median emargination at apex (Fig. 189); spermatheca pipe-shaped (Figs 186, 187). <b>Distribution</b> (Fig. 193) <i>Gnypeta minuta</i> is known only from New Brunswick, Canada. <b>Collection and habitat data</b> The two specimens were captured in June, one from under debris on muddy soil near a small pool in a silver maple forest, and the other from under debris on clay and sand mix at river margin.
