In North America, it has previously been recorded in Alaska (Leng 1920; Bousquet 1991) under the name <i>Atomaria fuscicollis</i> Mannerheim, 1852, synonymized by Johnson et al. (2007). In the Palaearctic region it is found throughout Europe (including Turkey), in Algeria in North Africa, across Siberia to the Russian Far East, south to Mongolia, and in central Asia in Iran and Uzbekistan (Johnson et al. 2007). In Atlantic Canada it has been collected in eastern hemlock, red spruce, and mixed forests, along a stream, and in a gypsum sinkhole. Lohse (1967) reported it in Europe from along rivers, under leaves. Johnson (1993) reported that it was, “a woodland species, mostly associated with broadleaved trees, it occurs on and under dead wood on the ground, in moss, leaf litter, flood refuse and general ground litter. It also occurs under hedgerows.” <b>Description:</b> Head, pronotum, and pro-, meso-, and meta-sterna piceous brown; elytra and abdominal sterna a slightly paler, fuscous brown; elytra becoming slightly paler in apical half. Head, pronotum, and elytra moderately densely, moderately strongly punctate; interspaces 1.0–1.5 times the diameter of punctures; apex of elytra slightly more finely punctate; elytral setae approximately the length of the interspaces, prominent and somewhat erect. Pronotum strongly constricted from midpoint to apex, parallel from midpoint to pronotal base; before base with a strong transverse impression, with several fine and sharp longitudinal ridges. Elytra scarcely, or not, wider than pronotum (Fig. 10). Antennae: antennomere 1 long and curved, twice as long as 2 and approximately twice as wide at apex than at base; 2 cylindrical; 3 as long as 2 but more slender; 4, 6, and 8 short and bead-like; 5 and 7 somewhat longer; club distinct; antennomeres 9 and 10 clearly transverse (Fig. 1.7). Body: width/length ratio, 0.31; length, 1.7–1.9 mm.
