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.

Ptinus bertranpetiti sp. nov. (Coleoptera: Ptinidae) is described from Socotra Island. The practical absence of secondary sexual dimorphism and the structure of the aedeagus, slender and subsymmetrical, suggest that the new species must be placed in the subgenus Gynopterus Mulsant & Rey, 1868. The most peculiar characteristics of P. bertranpetiti sp. nov. refer to the aedeagus and the elytral pubescence, both with features that are unparalleled in other species of the subgenus Gynopterus.
