【 摘 要 】

Damzenia groehni gen. et sp. nov., preserved in Baltic amber is described as the first fossil representative of the tribe Gempylodini (Zopheridae: Colydiinae). In addition to the typical general characters of zopherids and colydiines, the newly described beetle possesses the unique tarsal formula 4-5-4 and distinct subcoxal lines on the metaventrite and abdominal ventrite 1. The tarsal formula of the Eocene fossil can be considered an intermediate stage between tenebrionoids with 5-5-4 and tenebrionoids with 4-4-4 tarsal formula. Computer reconstructions of the habitat for the newly described beetle created with the use of the Terragen4 program and the Xfrog software are provided.
