A new genus and species of malachite beetles (Coleoptera, Dasytidae), Protomauroania chaetophorata Tshernyshev, gen. et sp. nov. are described from Late Eocene Baltic amber. The beetle belongs to subfamily Danaceinae, and is similar to the genus Mauroania Majer, 1997 due to the scalloped lateral side of pronotum, but differs in the following characters: antennae with 6-segmented club, surface covered with rufousbrown long semi-erect strong setae, and the strongly elongate basal tarsomeres in the hind tarsi.
