description: 17. <i>Gnypeta saccharina</i> Klimaszewski and Webster, sp. nov. urn:lsid:zoobank.org:act: 3F61ACAE-3402-4A0B-8464-78A52DF9AEA5 (Figs 19, 37 a, b, 172-180, 199) (Figs 19, 37 a, b, 172-180, 199) <b>HOLOTYPE</b> (male): <b>CANADA</b>, New Brunswick, Queens Co., Canning Grand Lake near Scotchtown, 45.8762&amp;ring; N. 66.1817&amp;ring; W., 25.V.2006, R. P. Webster coll.; silver maple swamp near lake margin, margin of vernal pond in moist leaves, IRM No. 1 (LFC). <b>PARATYPES</b>: New Brunswick, York Co., Fredericton, at Saint John River, 45.9588&amp;ring; N, 66.6254&amp;ring; W., 7. VI.2005, R.P. Webster coll., margin of river in flood debris (LFC, RWC) 3 females. <b>Etymology</b> The specific name “ <i>saccharina</i> ” derives from the Latin specific name of silver maple, <i>Acer saccharinum</i> L., in reference to the forest type where the holotype was captured. <b>Diagnosis</b> This species can be recognized by the following combination of characters: body length 2.4-2.7 mm (Fig. 19); elytra at suture as long as pronotum and about 1/6 wider than maximum width of pronotum (Fig. 19); abdomen at base slightly narrower than elytra and subparallel, tergal impressions without coarse punctation (Fig. 19); antennal article 4 strongly elongate, 5-7 moderately elongate, 8-10 subquadrate (Figs 37 a, b); median lobe of aedeagus with apical part narrowly triangularly produced with slightly sinuate edges in lateral view (Fig. 172); spermatheca pipe-shaped, capsule spherical with large apical invagination, stem narrowly elongate and sinuate (Fig. 178); male tergite 8 truncate apically (Fig. 176); female sternite 8 with large apical emargination (Fig. 180). The subquadrate antennal articles 7-10; distinct shape of spermatheca; medially emarginated female sternite 8, and the shape of the apical portion of the median lobe of the aedeagus are the best characters for recognition of this species. <b>Description</b> Body length 2.4-2.7 mm; dark brown (Fig. 19); integument moderately glossy; pubescence yellowish grey and very short and dense; antennal articles 5-7 moderately elongate, 8-10 subquadrate (Figs 37 a, b); head slightly narrower than pronotum (Fig. 19); elytra and abdomen (less so) wider than either head or pronotum; head rounded posteriorly; pronotum broadest in the middle, pubescence directed obliquely posterolaterad from the midline; elytra at suture as long as 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. 19); abdomen subparallel, distinctly narrower than elytra at base (Fig. 19); metatarsus with basal article slightly longer than the following article. <b>Male</b>. Tergite 8 truncate apically (Fig. 176). Sternite 8 elongate and broadly rounded apically (Fig. 177). Median lobe of aedeagus with narrowly triangular apex in lateral view (Fig. 172); bulbus moderately large in dorsal view (Fig. 173); internal sac with complex structures as illustrated (Figs 172, 173). <b>Female</b>. Tergite 8 truncate apically (Fig. 179). Sternite 8 broadly rounded posteriorly with deep V-shaped apical emargination (Fig. 180). Spermatheca club-shaped, capsule spherical apically and constricted basally, connected to a narrow tubular and sinuate stem (Fig. 178). <b>Distribution</b> (Fig. 199) <i>Gnypeta saccharinum</i> was described from two localities in New Brunswick and these are the only known localities for this species. <b>Collection and habitat data</b> Adults were captured in May from moist leaves near margin of vernal pond in silver maple (<i>Acer saccharinum</i> L.) swamp, and in June from flood debris at the margin of the Saint John River.
