A new genus and species of fossil Tenebrionidae is described. Yantaroxenos colydioides gen. et sp. nov. in the subfamily Lagriinae (presumably the tribe Belopini) originates from Baltic amber. Yantaroxenos gen. nov. is most similar to the Western Hemisphere genus Rhypasma Pascoe, 1862 (Belopini) based on the general habitus, the granulated pronotal surface, carinate elytra, and the carinate anterior aspect of the pronotum. Yantaroxenos gen. nov. differs from Rhypasma in the scaly pubescence on the body, the presence of ridges above the eyes, the strongly convex and protruding anterior half of the pronotum that covers the base of the head, the shorter legs, and the absence of 3-segmented antennal club.
