Abstract

Abstract. 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 ( µ CT). 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).

始新世Rovno琥珀中首次记录Brentidae(鞘翅目)，并描述了一种新的弓形舌龙化石，1893

摘要使用X射线微计算机断层扫描（µCT）从上始新世Rovnoamber描述了一种新的梨形象甲，Toxorhychus europeeocenicus Bukejs et Legalov，sp.nov.（鞘翅目：小蜂科：小蜂亚科）。新化石物种与已灭绝的Toxorhynchus robustus Poinar et Legalov，2015（多明尼加琥珀，下中新世）的不同之处在于体型更大、鞘翅纹更窄和毛宽。它是在罗夫诺琥珀中的第一个布伦科记录，也是在东半球的第一个毒蜥属记录（urn:lsid:zoobank.org/pub:8FB7B299-EE75-4556-B4EA-203A3BED84C）。
