Heterhelus buzina sp.n. (Coleoptera: Kateretidae) from Rovno amber: the first proxy for Sambucus in the Eocene of Eastern Europe

Heterhelus buzina sp.n. is described from Rovno amber. The new species seems similar to the extant H. scutellaris (Heer, 1841), but differs from its by size (length 1.8 mm), relatively small scape, longer elytra exposing two complete abdominal tergites, and confused elytral puncturation. All extant species of Heterhelus develop on Sambucus; the Heterhelus record from Rovno amber is the first indication of Sambucus presence in Eocene flora of Eastern Europe.
