Description. Body length 2.0– 2.5 mm, narrowly oval; head and pronotum usually rufotestaceous; elytra testaceous to light brown, mottled with small irregular darker spots or (rarely) black posteriorly; abdomen rufo-testaceous, apical part of abdomen sometimes darker. Punctation: vertex of head with about 10 large umbilicate punctures on each side, pronotum with two irregular median rows of large punctures, scattered punctures elsewhere, elytra with fine, sparse punctures. Microsculpture: reticulate throughout. Antennae as illustrated (Fig. 13). Pronotum 1.2 times as wide as long. MALE: tergite 8 with two lobe-shaped lateral teeth and usually with two to three small median teeth (Fig. 91); sternite 8 broadly rounded apically and with shallow median emargination (Fig. 92). Median lobe of aedeagus with tube-shaped tubus bearing two long ventral projections, apex rounded (Fig. 89), flagellum slightly projecting from the tip of median lobe (Fig. 89). Paramere as illustrated (Fig. 90). FEMALE. Tergite 8 truncate apically (Fig. 94); sternite 8 rounded apically (Fig. 95); spermatheca as illustrated (Fig. 93).

Bionomics. Macrohabitat: hardwood forest, on ridge with red oak surrounded by silver maple ( Acer saccharinum   L.) forest, mature mixed forest, mixed forest with hemlock, mature red spruce and red maple forest, eastern white cedar swamps, yellow birch, and spruce forest. This species has also been found in conifer forest and a white spruce ( Picea glauca (Moench) Voss   ) forest. Microhabitat: on/in gilled mushrooms, on Russula virescens (Schaeff.) Fr.   , in Climacodon septentrionale (Fr.) Kar.   on dead standing sugar maple ( Acer saccharum Marsh.   ), on Pleurotus   sp. on log. Also found on Heterobasidium
