description: V. <i>Gyrophaena</i> (<i>Gyrophaena</i>) <i>sculptipennis</i> species group (Seevers, 1951: 689) 8. <i>Gyrophaena</i> (<i>Gyrophaena</i>) <i>sculptipennis</i> Casey Figs 8, 57–63; Map 5 <i>Gyrophaena sculptipennis</i> Casey, 1906: 298; Seevers 1951: 689; Moore and Legner 1975: 431; Campbell and Davies 1991: 106. <b>Description.</b> Body length 1.9–2.2 mm, narrowly oval; head rufo-piceous to piceous; pronotum flavate; elytra flavate to dark brown; abdomen reddish-brown. Punctation: vertex of head with at least eight large umbilicate punctures on each side, pronotum with conspicuous puncture in median row on each side and with a few scattered punctures elsewhere, elytra moderately densely punctate. Microsculpture: weakly reticulate on head only. Antennae as illustrated (Fig. 8). Pronotum 1.4 times as wide as long. MALE: tergite 8 with two large rounded teeth and 2–5 smaller rounded median teeth (Fig. 59); sternite 8 broadly rounded apically (Fig. 60). Median lobe of aedeagus with moderately narrow tubus and acute apex projecting ventrally, apical projection small and narrow, directed anteriad in lateral view (Fig. 57), dorsal projection of internal sac narrowly elongate and sinuate (Fig. 57). Paramere as illustrated (Fig. 58). FEMALE. Tergite 8 shallowly emarginate posteriorly and with two lateral teeth (Fig. 62); sternite 8 broadly rounded posteriorly (Fig. 63); spermatheca as illustrated (Fig. 61). <b>Bionomics. Macrohabitat</b> : mixed forest, mature mixed forest, regenerating mixed forest, hardwood forest, maple forest, red oak and red maple forest, mature red spruce <b>Map 5.</b> Collection localities in New Brunswick, Canada of <i>Gyrophaena sculptipennis</i> and red maple forest, hemlock forest (120+ years old), forested black spruce bog with red maple. <b>Microhabitat:</b> on/in gilled mushrooms on forest floor, on stalked polypore mushrooms on forest floor, and on <i>Pleurotus</i> sp. on log. <b>Collecting period:</b> June, July, August and September. <b>Collecting method:</b> sifting mushrooms, aspirating, and hand collecting specimens. <b>Distribution</b> (Map 5). CANADA: <b>New Brunswick</b> and Nova Scotia, Quebec; UNITED STATES: New Hampshire, New York, and Wisconsin. <b>Comments.</b> Our specimens agree in all respects with the description and illustrations of this species by Seevers (1951), but tergite 8 of males in our specimens has only 2–4 median small teeth while in Seever’s illustration there are 5 small median teeth. We attribute this difference to intra-specific variation.
