BODY: Length 1.68–1.80 mm; brown, some with elytra red-brown; setae on head, pronotum, and elytra short, curved and suberect, decumbent over rest of body. Head: surface smooth, shining, punctures indistinct. Antennomere III-VI longer than wide, VII as long as wide, VIII–X transverse, VIII about two-thirds width of IX (Fig. 25 E). Median vertexal fovea as wide as lateral foveae. Pronotum: surface smooth, shining, punctures indistinct. Median antebasal fovea with setose area as wide as those of lateral antebasal foveae. Elytra: with faint microreticulation, punctures indistinct, discal stria extending to about four-fifths of elytral length. Abdomen: basal striae of tergite 1 long, about one-half length of paratergites, separated at base by two-fifths tergite width at base, basal comb of setae between striae slightly denser in males than in females; disc smooth, shining, punctures indistinct. MALE: Antennae and trochanters not modified. Metaventrite with short triangular patch of longer, appressed setae between metacoxae. Tergite 1 with apex angled to become prominent at middle, appearing humped in lateral view, apical margin with shallow emargination at middle, lacking setal lamina; tergite 2 with deep V-shaped impression extending from tergite base to near apex, apical portion of impression with prominent margins, strongly protruding dorsally in lateral view, posterior margin of protuberance vertical; with two appressed setal tufts at apex of protruding margin, complex tubercle extending from base of impression at angle to meet apical margin of tergite 1; lateral portions of tergite 2 slightly flattened and coarsely punctate (Figs 25 A–D); in lateral view tergite 1 rising to apex, 2 gently curving dorsally with posterior face nearly vertical, base of 2 well-separated from 1. Abdominal ventrites broadly curved. Metatibiae thin, narrow at base, gradually widened to near apex, mesal margin of apical sixth with brush present (Fig. 25 F). Aedeagus 0.32 mm long; dorsal plate triangular, margins evenly converging to acute point; parameres truncate at apex, three thick setae on lateral margin at angle of preapical constriction; hyaline seta on mesal margin, small, thickened to middle, with acute apex; internal sac with three thick spines, one short, none strongly curved (Fig. 25 G). FEMALE: Metaventrite with denser setae in area between metacoxae, sparse over rest of metaventrite. Abdominal tergites gently convex, lacking modifications; ventrites broadly convex. Metatibiae similar to that of male. Collection data: From alder and sphagnum litter in marshes; in beaver houses and muskrat nests; in beach debris; at UV light (Chandler 1997); also from leaf litter along streams. Habitat data from specimens indicates that this species is found in leaf litter along lake margins and in swamps/marshes. Several series have been taken from debris in beaver huts. This is a species of the Northeast and Midwest regions, with all collections but one being
