ABSTRACT. Atomaria saxonica Lyubarsky et Perkovsky sp.n., a first cryptophagid species from Bitterfeld amber, is described. The new species is the third described Eocene species of Atomariinae. The new species is similar to A. testacea Stephens, 1830 and A. analis Erichson, 1846. It differs from these species by the structure of antennae. The new species differs from other extinct Atomaria species in shape of pronotum, not narrowed towards base. Shixitomaria gen.n. is established for Atomaria cretacea Cai et Wang, 2013 from the Early Cretaceous of China. Mesozoic fauna of Cryptophagidae consist of five extinct genera; in Cenozoic cryptophagid fauna extinct genera unknown. The genera from Miocene of Shandong, Elytrophagus Zhang, 1989 and Plastophagus Zhang, 1989, probably do not belong to Cryptophagidae.
KEY WORDS. Atomariinae, Shixitomaria, Elytrophagus, Plastophagus, Late Eocene, Shixi Formation.
