The fossil specimens under consideration are placed in Cryptophagidae based on antennae 11-segmented with 3-segmented loose club; tarsal formula 5-5-5; incomplete epipleura; elytra completely covering abdomen, with irregular punctation; procoxal cavities closed externally; tarsomeres simple, not lobed; and abdominal ventrite 1 longest. A new extinct species are assigned to the subgenus Anchicera within the genus Atomaria based on the combination of the following characters: distance between antennal insertions larger than distance between antennae and аnterior margin of eye; and lateral sides of elytra widely rounded, not parallel.</p></div>	https://treatment.plazi.org/id/F93FF74CE97EFFDD0ACE08E4DD77FC37	Public Domain	No known copyright restrictions apply.
