First fossil representative of the family omalisidae (Coleoptera, Elateroidea sensu lato) from the Baltic amber

摘要

The paper describes Jantarokrama utilis Kovalev et Kirejtshuk, gen. et sp. nov., the first fossil representative of the family Omalisidae from the Upper Eocene Baltic amber, which is similar to the Recent Phaeopterus unicolor Costa, 1856, but distinguished from the latter by the larger and not so slender body, smaller distance between antennal insertions, longer antennae, wider prothorax with very convex anterior edge of the pronotum, and particularly by five completely exposed abdominal ventrites. The diagnosis of the new genus among generic taxa of Omalisidae and its similarity to Berendtimirus Winkler, 1987 (Berendtimiridae) are discussed.
