A new species of the genus Anthonomus Germar (Curculionidae) in Mexican amber

New genus of the tribe Ceutorhynchini (Coleoptera: Curculionidae) from the late Oligocene of Enspel, southwestern Germany, with a remark on the role of weevils in the ancient food web

“…The earliest reliable species of the tribe Ceutorhynchini, provisionally placed in the genus Ceutorhynchus Germar, 1823, is described from the early-middle Eocene of Green River Formation (Scudder, 1893;Legalov, 2015). Three species of the genus Ceutorhynchus and Baltocoeliodes sontagae Legalov & Bukejs, 2018 from the tribe Ceutorhynchini are described (Legalov, 2013(Legalov, , 2020aLegalov and Bukejs, 2018), and one species of the genus Rhinoncus Schoenherr, 1825 (Phytobiini) is recorded from the middle-upper Eocene Baltic amber (Klebs, 1910). The most ancient Cnemogonini and four species of Ceutorhynchini are found in the terminal Eocene of Florissant (Scudder, 1893;Wickham, 1916;Legalov, 2015).…”

<i>Groehnius</i>, a new genus of Eugnomini (Coleoptera: Curculionidae) from Eocene Baltic amber

“…The subfamily Curculioninae is a morphologically very diverse group and includes more than 30 tribes in the Holocene fauna (Caldara et al, 2014). The oldest representative of the tribe Curculionini from this subfamily is known from the Paleocene of Menat (Legalov et al, 2017). The Curculioninae from fossil resin usually are known by type specimens only (Legalov, 2015): the tribes Acalyptini, Curculionini, Ellescini, Eugnomini, Rhamphini and Tychiini are known from the lowermost Eocene Oise (Legalov et al, 2019a) and Upper Eocene Baltic and Rovno ambers (Kuśka, 1996;Rheinheimer, 2007;Legalov, 2016a, b;Legalov et al, 2019b); and the tribes Anthonomini, Derelomini and Tychiini are found in the Early Miocene Dominican and Mexican ambers (Poinar Jr. and Legalov, 2015;Legalov and Poinar, 2016;Legalov, 2019).…”
