brown or light brown with piceous posterior portion. Punctation: vertex of head with at least six small punctures on each side; pronotum with median rows of usually three punctures and a small cluster medially near base of disc; elytra sparsely and irregularly punctate. Microsculpture: finely meshed and strong on head and pronotum. Antennae as illustrated (Fig. 4). Pronotum 1.4 times as wide as long. MALE: tergite 8 with two long lateral teeth and two shorter median teeth (Fig. 34); sternite 8 broadly arcuate apically (Fig. 35). Median lobe of aedeagus with narrowly triangular tubus sinuate laterally (Figs 31, 32), dorsal projection of internal sac tubular and short, flagellum everted and coiled (Fig. 32), compressor plate elevated (Fig. 32). Paramere as illustrat- ed (Fig. 33). FEMALE. Tergite 8 truncate apically (Fig. 37); sternite 8 apically pointed (Fig. 38); spermatheca as illustrated (Fig. 36).

Bionomics. Macrohabitat: Mature mixed forest, 8.5-year-old regenerating mixed forest, eastern white cedar ( Thuja occidentalis L.) swamps and red spruce ( Picea rubens Sarg. ) and red maple ( Acer rubrum L.) forest (80–120 years old). This species has been found in a conifer forest and an eastern hemlock forest [ Tsuga canadensis (L.)] (120+ years old). Microhabitat: Gilled fungi on rotten log, in gilled mushrooms, in gilled mushrooms on stump, in moss near brook, on polypore fungi on dead standing Populus sp. Collecting period: June, July, August, and September. Collecting method: sifting mushrooms, aspirating and hand picking specimens.

Distribution (Map 1). CANADA: Alberta, British Columbia, New Brunswick, Ontario, Quebec, Yukon Territory; UNITED STATES: Florida, Maine, Massachusetts, Montana, New Hampshire, New York, Tennessee, Washington and Wyoming.
