Abstract
A new fossil species of the superfamily Tenebrionoidea, Coslonatus rasnitsyni gen. et sp. nov., is described and illustrated from the mid-Cretaceous Burmese amber. The new genus is tentatively placed in the extant subfamily Colydiinae (Zopheridae) based primarily on the 4-segmented tarsi, clubbed antennae, and all freely connected abdominal ventrites. Coslonatus is unique in Colydiinae in having dorsally located antennal insertions and markedly long antennae, suggesting a unique ecological niche of the new species.
