Microsculpture: reticulate throughout but weaker on elytra. Antennae as illustrated (Fig. 24). Pronotum 1.4 times as wide as long. MALE: tergite 8 with two small lateral teeth and usually with two minute median teeth (occasionally only one tooth present or the teeth reduced to small tuberosities), apical margin slightly emarginate medially (Fig. 161); sternite 8 rounded apically (Fig. 162). Median lobe of aedeagus with complex tubus, its apex <b>Map 2Ι.</b> Collection localities in New Brunswick, Canada of <i>Gyrophaena flavicornis</i> with subapical hook-like projection (Fig. 159), apical projection of internal sac elongate and truncate apically (Fig. 159).
