Except for protruding eyes, slightly more transverse pronotum, and longer body, this species is not externally distinguishable from <i>S. hampshirensis</i>. <b>Description.</b> Body length 1.8–2.1 mm, width 0.3–0.4 mm, approximately uniformly dark brown with tarsi or entire legs, base of antennae and mouthparts paler (Fig. 4); integument with weak microsculpture, sculpticells irregularly hexagonal, pubescence short, except for slightly longer on head and abdomen, yellowish-brown in artificial light, moderately dense. Head approximately round, feebly carinate basally, tempora as long as approximately three times the maximal diameter of eye seen from above (Fig. 4); antennae slim with articles 5–10 from moderately transverse (Fig. 4); pronotum strongly transverse, broadly rounded laterally and posteriorly, broadest in basal half, pubescence directed anteriorly on apical third of the midline and obliquely laterally elsewhere (Fig. 4); elytra short, strongly transverse, subparallel, hind margin approximately straight, pubescence directed straight posteriad (Fig. 4); abdomen parallel-sided, three basal tergites strongly impressed basally (Fig. 4). <b>Male.</b> Tergite 8 emarginate apically with irregular crenulation and two large lateral teeth (Fig. 20); sternite 8 elongate and slightly produced apically (Fig. 38). Median lobe of aedeagus moderately broad, less than in other species of the genus, and flattened, venter of tubus arcuate, apex slightly produced ventrally (Figs 35, 36), apical sclerites of internal sac V-shaped in dorsal view (Fig. 34); paramere as illustrated (Fig. 33). <b>Female.</b> Tergite 8 truncate apically (Fig. 41); sternite 8 broadly rounded apically (Fig. 42). Spermatheca S-shaped, with tubular capsule, and stem angularly bent posteriorly (Fig. 39). Aberrant form of spermatheca is shown in Fig. 40. <b>Bionomics.</b> Adults were captured in <i>Carex</i> and <i>Typha</i> marshes, in litter and grass at the base of dead red maples, in a <i>Carex</i> marsh (probably an overwintering site), tread- <i>First record of the genus</i> Schistoglossa <i>Kraatz</i> <i>from Canada...</i> 63 <b>39</b> <b>0.2 mm</b> 33 35 34 40 36 37 38 4Ι 42 <b>Figures 33–42.</b> <i>Schistoglossa brunswickensis</i>: <b>33</b> paramere <b>34</b> median lobe of aedeagus in dorsal view <b>35, 36</b> median lobe of aedeagus in lateral view <b>37</b> male tergite 8 <b>38</b> male sternite 8 <b>39</b> typical form of spermatheca <b>40</b> aberrant form of spermatheca <b>4Ι</b> female tergite 8 <b>42</b> female sternite 8. <b>80° 0' 0" W 70° 0' 0" W 60° 0' 0" W</b> <b>50° 0' 0" N</b> <b>40° 0' 0"</b> <b>90° 0' 0" W 80° 0' 0" W 70° 0' 0" W</b> <b>Map 4.</b> Collection localities in Canada of <i>S. brunswickensis.</i> ing vegetation in a <i>Carex</i> marsh, in moist grass litter on muddy soil at a beaver pond and bank of a stream, in April, May, and June. <b>Geographic distribution</b> (Map 4).
