A new fossil species from the Eocene Baltic amber of the extinct tribe Mimoplatycini Kazantsev, 2013 (Cantharidae Malthininae), is illustrated and described here. Mimoplatycis marchettii sp. nov. is characterized by a transverse but interrupted carina in the middle of pronotum. The tribe is known from Baltic and Rovno amber, and the pronotum with carinae similar to Lycidae could be interpreted as mimicry. The pronotal shape is here indicated as a diagnostic character of the species level.
