ABSTRACT. In the Paleontological Institute’s collection the two new fossil specimens of Cryptophagidae were found in Late Eocene Baltic amber. One specimen belongs to the genus Micrambe Thomson, 1863. This specimen was identified as Micrambe sarnensis Lyubarsky et Perkovsky, 2010. Earlier this species was found in Rovno amber, but the new specimen is from Baltic amber. A redescription of M. sarnensis is presented in this paper. An important character of the species is a large callosity occupying a quarter to a third of the lateral edge of the pronotum, and ending in a thin spike at the apex. Another specimen belongs to the genus Atomaria Stephens, 1829. This specimen was identified as A. groehni Perkovsky et Lyubarsky, 2014 earlier described from Baltic amber. A redescription of the species A. groehni is presented.
