New fossil species of Trichodesma LeConte, 1861 (Coleoptera: Ptinidae) from Eocene Baltic amber collected in the Kaliningrad region, Russia

[摘要] Based on a well-preserved specimen from Eocene Baltic amber (Kaliningrad region, Russia), Trichodesma fennosarmatica sp. nov. is described and illustrated. It is the fourth fossil species of this genus. The new species is similar to the extinctTrichodesma electra Zahradník and Háva, 2017, T. groehni Zahradník and Háva, 2017, and T. amberica Zahradník and Háva, 2017 from Baltic amber, but differs in the number of elytral tufts of erect setae that are present. A key to fossil species of Trichodesma is provided.
