Abstract: Reliquantha eocena sp. nov. (Diptera: Anthomyzidae), male only, is described from a Baltic amber inclusion (Tertiary: Middle Eocene, 38?50 mya) and its relationship is discussed. Based on analysis of morphological characters it is affiliated with Reliquantha Roháček, 2013 and is thus the first fossil species of Anthomyzidae belonging to an extant genus. The diagnosis of Reliquantha is slightly modified and its relationship to fossil Lacrimyza Roháček, 2013 (also from Baltic amber) is confirmed. A key to fossil (all Tertiary) genera and species of the subfamily Anthomyzinae is presented.
