In North America it has previously been recorded from southern California (Leng 1920) under the name <i>Atomaria ruficornis</i> Marsham, 1802, synonymized by Johnson et al. (2007). LeConte (1869, 258) reported a species from South Carolina under the name of <i>Atomaria testacea</i> Zimmerman; however, as Bousquet (1989) makes clear, this refers to <i>Cryptophagus ferrugineus</i> Sahlberg. In the Palaearctic region it is found throughout Europe, in Algeria, Morocco, and Tunisia in North Africa, and in Asia in Turkey, Kazhakhstan, Mongolia, and western Siberia (Johnson et al. 2007). In Atlantic Canada it has been found in red spruce forests, boggy areas and marshes, in pastures, fields, meadows, and open areas, on beaches under wrack, in a ravine, and in compost. Johnson (1993) reported that it was, “mainly a grassland species which has been recorded around farms, gardens and parks, but it often occurs in other habitats. It has been collected in man-made heaps of refuse, especially cut vegetation, grass, hay, haystack bottoms and compost, more rarely in dung or dung heaps.” <b>Description:</b> Head and prontotum piceous. Elytra piceous basally, gradually becoming paler in the apical half. Venter: pro-, meso-, and meta-sterna piceous; abdominal sterna and legs dark testaceous. Head finely, moderately sparsely, punctate. Pronotum and elytra moderately finely and densely punctate, interspaces 1.0–1.5 times the diameter of punctures, elytral punctures becoming finer apically; pronotum widest at midpoint, constricted towards base and apex; base with only a very shallow transverse impression (Fig. 9). Antennae: antennomere 1 swollen, slightly curved and expanded at apex; 2 smaller than 1 but also apically expanded; 3 almost as long as 2 and only slightly more slender; 4–8 short and somewhat bead-like; antennal club distinct; antennomeres 9 and 10 transverse (Fig. 1.8). Body: width/length ratio, 0.46; length, 1.3–1.6 mm. <b>Québec Newfoundland</b> <b>Gaspe</b> <b>Prince Edward Cape Breton Island Island New Brunswick Haine Nova</b> <i>Atomaria apicalis</i> <b>Scotia</b> Atomaria nigrirostris <b>Figure Ι6.</b> Distribution of <i>Atomaria apicalis</i> and <i>Atomaria nigrirostris</i> in Atlantic Canada.
