KEYWORDS: Atomaria, Cryptophagidae, new species, Eastern Palaearctic, Siberia, Far East. КЛЮЧЕВЫЕ СЛОВА: Atomaria, Cryptophagidae, новые виды, Восточная Палеарктика, Сибирь, Дальний Восток. ABSTRACT. Two new species of Cryptophagidae are described from Siberia and Far East: Atomaria aleatoria sp.n. and A. acerba sp.n. РЕЗЮМЕ. Из Сибири и Дальнего Востока России описано два новых вида рода Atomaria Stephens, 1829: A. aleatoria sp.n. и A. acerba sp.n.
bent pale pubescence of moderate length. Head and prothorax dark brown or blackish, elytra reddish brown; antennae and legs reddish-brown. Antennal structure as in Fig. 1, segment 1 ca. 2 times as long as broad, segments 9 and 10 strongly transverse. Pronotum distinctly transverse, broadest at or just behind the middle where it is 1.31.4 times as broad as long, thence contracted the base where it is narrower than the base of the elytra; side borders only visible from above in the basal third; surface strongly and coarsely shagreened over the whole surface, moderately strongly and moderately densely punctured, punctures separated by 0.51.0 diameters apart from their lateral neighbours; base of the pronotum with a narrow and well-defined depression in the middle; hind angles obtuse; pronotal disk convex; hind margin finely bordered. Elytra long oval, moderately arched, weakly curved at the sides, broadest near in middle, 2.52.7 times as long as the pronotum, 1.41.5 times as long as together broad. Surface shining, strongly shagreened, rather closely punctured, the punctures in the basal part slightly smaller than those on the pronotal disk, and approximately 1.01.5 diameters apart from their lateral neighbours on an average; elytral humeri toothed or not. Hind wings fully developed. Male genitalia as in Fig. 2. REMARKS. This species differs from nearest species with transversal club of antennae and elongated 1st segment of antennae (similar with A. elongatula Erichson 1846, A. abietina J.R.Sahlberg 1888, but A. aleatoria sp.n. with elongated 1st segment of antennae); similar with A. vespertina Maklin 1853, but A. aleatoria sp.n. with transversal club, strongly rounded sides of pronotum, and strongly excised aedeagus.

Introduction
This work is chiefly based on material from Zoological Museum of Moscow State University (ZMMU). All materials, including types, have been deposited in this museum. The cryptophagid fauna of Palaearctic in currently known to contain 368 species [Johnson, 2007], including about 127 species from the genus Atomaria. Palaearctic is better investigated region, but at the species level the fauna of the Palaearctic realm studied insufficiently.

DESCRIPTION. Length 1.61.9 mm, elongate (Fig. 3), moderately arched, covered with slightly curved but decumbent pale pubescence of moderate length. Head and prothorax dark brown or blackish, elytra reddish brown; antennae and legs reddish-brown. Antennal structure as in Fig. 3, segment 1 is 1.62.0 times as long as broad, segments 9 and 10 weakly transverse. Pronotum 1.31.4 times as broad as long, distinctly transverse, broadest behind the middle, then contracted to the base where being narrower than the base of the elytra; side borders only visible from above in the basal third; surface strongly and coarsely shagreened over the whole surface, moderately strongly and moderately densely punctured, punctures separated by 0.5 diameters apart from their lateral neighbours; base of the pronotum with a narrow and weakly depression in the middle; hind angles obtuse; pronotal disk convex; hind margin finely bordered.

Elytra long oval, moderately arched, weakly curved at the sides, broadest near in middle, 2.32.6 times as long as the pronotum, 1.51.7 times as long as together broad. Surface shining, strongly shagreened, rather closely punctured, the punctures in the basal part slightly smaller than those on the pronotal disk, and approximately 1.01.5 diameters apart from their lateral neighbours on an average; elytral humeri toothed or not. Hind wings fully developed. Male genitalia as in Fig. 4. REMARKS. This species differs from nearest species with decumbent pubescence, weakly transversal club of antennae and short 1st segment of antennae. A. gracilicornis Reitter 1888 and A. wollastoni Sharp 1867 differ from A. acerba sp.n. in the following characters: elongated 1st segment of antennae, very narrow 9th segment of antennae, and weakly transverse pronotum. A. acerba sp.n. differs from A. vespertina in the following characters: elongated 1st segment of antennae, very narrow 9th segment of antennae, weakly transverse of pronotum too (sometimes club of antennae more transverse), and genital characters. A. acerba sp.n. differs from A. gracilicornis, and A. edithae Reitter 1888 in the following characters: rounded hind angles of pronotum, and unicolorous red colour (its differs from A. edithae in outstanding pubescence).
