The first record of Brentidae (Coleoptera) in Eocene Rovno amber with description of a new fossil species of Toxorhynchus Scudder, 1893

A new pear-shaped weevil, Toxorhynchus europeoeocenicus Bukejs et Legalov, sp. nov. (Coleoptera: Brentidae: Apioninae), is described from upper Eocene Rovno amber using X-ray microcomputed tomography (µCT). The new fossil species differs from the extinct Toxorhynchus robustus Poinar et Legalov, 2015...

Zusammenfassung:A new pear-shaped weevil, Toxorhynchus europeoeocenicus Bukejs et Legalov, sp. nov. (Coleoptera: Brentidae: Apioninae), is described from upper Eocene Rovno amber using X-ray microcomputed tomography (µCT). The new fossil species differs from the extinct Toxorhynchus robustus Poinar et Legalov, 2015 (Dominican amber, lower Miocene) in the larger body size, narrower elytral striae, and wider pronotum. It is the first record of the family Brentidae in Rovno amber and the first record of the genus Toxorhynchus in the eastern hemisphere (urn:lsid:zoobank.org:pub:8FB7B299-EE75-4556-B4EA-203A3CBED84C).
