ABSTRACT
Xenophagus simutniki sp. n. is described from a late Eocene Rovno amber specimen. The new species is similar to the fossil Xenophagus popovi Lyubarsky et Perkovsky, 2017 from the late Eocene Baltic amber (W Russia), differing in the medially notched anterior margin of the pronotum. The Rovno xenosceline fauna is the richest among both extant and extinct faunas. This fauna includes the extinct genera Xenophagus Lyubarsky & Perkovsky, 2017 and Xenohimatium Lyubarsky & Perkovsky, 2012, which are closest to the extant Mediterranean Xenoscelis Wollaston 1864 and the representative of the extant boreal genus Zavaljus Reitter, 1880. A key to extinct species of the subfamily Xenoscelinae is presented. The possible reasons of xenoscelines abundance in European amber forests are discussed.
ABSTRACT
Based on well-preserved specimen in Eocene Baltic amber, Atomaria (Anchicera) propinqua sp. nov. is described and illustrated. It is the sixth fossil species of Atomaria Stephens, 1829 reported from fossil resins. In addition, a new fossil record of A. (Anchicera) alekseevi Lyubarsky et Bukejs, 2022 from Baltic amber is presented.
