Abstract
Dieneremia rueckeri gen. et sp. nov. is described and illustrated from Upper Eocene Baltic amber (Yantarny village, the Kaliningrad Region, Russia). A new synonymy is established: Latridius jacquelinae Hawkeswood, Makhan and Turner, 2009 = Latridius jantaricus Borowiec, 1985. New fossil records on Latridius jantaricus Borowiec, 1985 are presented.
