New fungus weevils, Eduardoxenus unicus (ZooBank BC85-9148-4FE5-A4F6-46847BA0138D, act:4D3B3EA8-AE0E-4E6D-A770-B427AC19ED03) Legalov,Nazarenko et Perkovsky, gen. et sp. nov. (Coleoptera: Anthribidae), aredescribed from late Eocene Rovno amber. The new genus is similar to the genusCyptoxenus Valentine, 1982, but differs in coarsely faceted eyes,antennomere 2 shorter than antennomere 1 and an almost glabrous body. Itdiffers from the genus Valenfriesia Alonso-Zarazaga et Lyal, 1999 inthe coarsely faceted eyes, almost straight transversal carina on the pronotumand distinct elytral humeri, and it differs from the genus NeoxenusValentine, 1999 in distinct lateral carina on the pronotum, coarsely facetedeyes and almost straight transversal pronotal carina. This fossil fungusweevil is the oldest finding of the tribe Valenfriesiini in fossil state andthe first record of the Choraginae from the Eocene amber. Thepalaeogeographical and palaeoclimatological importance of findingValenfriesiini in Rovno amber is discussed.
