Synonymized by Seevers 1951: 718. <b>Description.</b> <i>Gyrophaena uteana</i> is externally similar to <i>G. gaudens</i> but the latter species has infuscated antennae while the former has antennae approximately uniformly light yellow. Body length 1.4–1.7 mm, narrowly oval; head piceous; pronotum brown to piceous; elytra brown or reddish-brown with piceous sutural region and posterior angles; abdomen reddish-brown, apical part often darker and piceous. Punctation: vertex of head with at least six moderately-sized umbilicate punctures on each side, pronotum with six punctures in two confused median rows and additional punctures elsewhere, elytra with fine, sparse punctures. Microsculpture: reticulate throughout except for pronotum, most evident on head. Antennae as illustrated (Fig. 22). Pronotum 1.5 times as wide as long. MALE: tergite 8 with two long and narrow lateral teeth and two very small median teeth close to each other (Fig. 147); sternite 8 rounded apically (Fig. 148). Median lobe of aedeagus with long and narrowly produced tubus bearing large angular swelling in the <b>Map Ι9.</b> Collection localities in New Brunswick, Canada of <i>Gyrophaena uteana</i> <b>25. <i>G. subnitens</i> 26. <i>G. meduxnekeagensis</i> 27. <i>G. polita</i></b> <b>Figures 22–27.</b> <i>Gyrophaena</i> species in dorsal view (apical part of abdomen removed): <b>22</b> <i>G</i>.
