Abstract: Seven new extinct species belonging to two subgenera (Amelyris Tshernyshev, Alekseev, Bukejs, Vasilenko, Legalov & Perkovsky, subgen. nov. and Asymelyris Tshernyshev, Alekseev, Bukejs, Vasilenko, Legalov & Perkovsky, subgen. nov.) within extinct genus Amelyris Tshernyshev, Alekseev, Bukejs, Vasilenko, Legalov & Perkovsky, gen. nov. are described and illustrated from inclusions in late Eocene European ambers (Baltic, Rovno, and Danish) as the first reliable fossils of the family Melyridae. The newly described taxa are included in the new tribe Amelyrini Tshernyshev, Alekseev, Bukejs, Vasilenko, Legalov & Perkovsky, trib. nov., which can be distinguished from the extant tribes of the subfamily by the following characters: (1) penultimate antennomeres oval-triangular with rounded edges, (2) elytral punctation between longitudinal carinae regular, arranged in three rows, (3) pronotum with strongly carinate lateral sides, (4) pronotal surface with pronounced foveolate punctation, (5) tarsomeres with strong semi-erect dark setae ventrally, and (6) body size comparatively small (2.53.8 mm). The keys to subfamilies and tribes of Melyridae, as well as to all species of the newly described genus, namely Amelyris (Amelyris) sveneldi Tshernyshev, Alekseev, Bukejs, Vasilenko, Legalov & Perkovsky, sp. nov., A. (Amelyris) elongatus Tshernyshev, Alekseev, Bukejs, Vasilenko, Legalov & Perkovsky, sp. nov., A. (Amelyris) tricarinatus Tshernyshev, Alekseev, Bukejs, Vasilenko, Legalov & Perkovsky, sp. nov., A. (Asymelyris) paucidentatus Tshernyshev, Alekseev, Bukejs, Vasilenko, Legalov & Perkovsky, sp. nov., A. (Asymelyris) lupatus Tshernyshev, Alekseev, Bukejs, Vasilenko, Legalov & Perkovsky, sp. nov., A. (Asymelyris) groehni Tshernyshev, Alekseev, Bukejs, Vasilenko, Legalov & Perkovsky, sp. nov., and A. (Asymelyris) jutlandicus Tshernyshev, Alekseev, Bukejs, Vasilenko, Legalov & Perkovsky, sp. nov., are provided.
