ABSTRACT. Based on a fossil specimen from the Late Eocene Bitterfeld amber, Microzavaljus saxonicum gen.n., sp.n., is described. The new genus belongs to subfamily Xenoscelinae Ganglbauer, 1899 (Coleoptera: Erotylidae). The new genus is similar to the extinct genus Warnis Lyubarsky, Perkovsky et Alekseev, 2016, differing in submetacoxal lines absent, and similar to extant genus Zavaljus Reitter, 1880, differing in body size, supraocular lines present, and pronotal sides smooth, not serrate. Eocene fauna of Xenoscelinae is now composed of 4 genera: Xenochimatium Lyubarsky et Perkovsky, 2012 from Rovno amber, Xenophagus Lyubarsky et Perkovsky, 2017 and Warnis Lyubarsky et al., 2016 from Baltic amber, and the new genus from Bitterfeld amber.

KEY WORDS: Erotylidae, Xenoscelinae, Microzavaljus, taxonomy, Late Eocene, Bitterfeld amber.
