A new species of Xyletinus Latreille, 1809 (Coleoptera: Ptinidae: Xyletininae) from Eocene Baltic amber, with a key to known fossil species

A new extinct species of the genus Xyletinus Latreille, 1809, namely X. (s. str.) lobanovi sp. n., is described and illustrated from Eocene Baltic amber. This new extinct species resembles X. carsteni Háva et Zahradník, 2020 but differs from it in the dull, not shiny pronotum and elytra, uniformly rufous body and appendages and the lesser body size. A new species is close to X. arturi Háva et Zahradník, 2019, but can be distinguished in the lesser body size, flat elytral intervals and the widest in anterior one-third pronotum. A key to fossil species of Xyletinus is provided. Additionally, new fossil records for Ernobius nadravicus Alekseev, 2014 and Xyletinus arturi Háva et Zahradník, 2019 are presented.
