We have examined the holotype of <i>Atomaria saginata</i> Casey 1900 deposited in the Smithsonian Institution and have found it to be identical in all respects to <i>A. fuscata</i> Schönherr. We therefore designate <i>A. saginata</i> (syn. n.) as a junior synonym of <i>A. fuscata</i>. <i>Atomaria fuscata</i> is newly recorded in Labrador, New Brunswick, insular Newfoundland, Nova Scotia, and Prince Edward Island (Figs 13, 17). Johnson et al. (2007) designated <i>Atomaria ochracea</i> Zimmerman, 1869 as a junior synonym of <i>A. fuscata,</i> and <i>Atomaria lacustris</i> Casey, 1900 and <i>Atomaria pennsylvanica</i> Casey, 1900 had previously been designated as junior synonyms of <i>A. ochracea</i> (by Leng 1920). Majka and Shaffer’s (2008) discussion of <i>A. ochracea</i> is attributable to <i>A. fuscata</i>. This species has been recorded in British Columbia, the District of Columbia, Idaho, Indiana, Maine, Manitoba, Maryland, Michigan, New Hampshire, New York, Ontario, Oregon, Pennsylvania, Rhode Island, Québec, Virginia, Washington, and Wisconsin (LeConte 1869; Blatchley 1910; Leng 1920; Procter 1946; Hatch 1961; Oatman et al. 1964; Bousquet 1991; Downie and Arnett 1996; Chandler 2001; Sikes 2004). In the Palaearctic region it is known throughout Europe, across Siberia to the Russian Far East, south to Tibet and northern China, and in the Middle East in Turkey and Israel (Johnson et al. 2007). Hatch (1961) reported it as very common on herbiage and in grass clippings, compost, leaf litter, and humus. In Atlantic Canada it has been collected in mixed and coniferous forests, pastures, blueberry and potato fields, hedgerows, in coastal dunes and on ocean beaches under drift, by freshwater ponds, and in compost. Johnson (1993) reported that it, “occurs in a range of habitats – grassland, wetland, and woodland – especially in damp situations, and has been collected in litter, moss, flood refuse, cut vegetation and compost heaps.” <b>Description:</b> Dorsum and venter usually dark red-brown castaneous, pronotum occasionally darker than elytra. Legs reddish-testaceous. Pronotal punctures moderately fine and dense apically, becoming progressively coarser and denser basally; pronotum widest at middle, strongly narrowing basally and apically; base with a distinct transverse impression, the middle third of the basal margin with a discernable, fine marginal bead. Elytral punctures very fine and sparse; interspaces between punctures 3.0+ times the diameter of punctures. Setae the length of the interspaces, appressed (Fig. 5). Antennae: antennomere 1 swollen, longer and wider than 2; 3 as long as or longer than 2 but more slender; 4–8 small and somewhat bead-like; antennal club distinct; antennomeres 9 and 10 quadrate, not discernibly transverse (Fig. 1.4). Body: width/length ratio, 0.47; length, 1.4–1.7 mm.
