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 extinct Trichodesma electra Zahradnik and Hava, 2017, T. groehni Zahradnik and Hava, 2017, and T. amberica Zahradnik and Hava, 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.
