A new species, weevil Pseudanthonomus antonkozlovi sp. nov., from Early Miocene Mexican amber is described and illustrated. The new species differs from P. rufulus Dietz, 1891 from Canada and USA in the larger body size, long rostrum, and wider femora. It is the first fossil record of the genus Pseudanthonomus and the second representative of the tribe Anthonomini described from Mexican amber.
Species of the genus Belonotaris Arnoldi, 1977 with a straight rostrum from the Middle-Upper Jurassic of Kazakhstan and China are revised. Arnoldibelus Legalov, 2009, syn. nov. and Sinoeuglypheus Yu, Davis et Shih, 2019, syn. nov. are synonymized with Belonotaris. The diagnosis of Belonotaris is supplemented, and its family placement is established. A key to B. daohugouensis (Yu, Davis et Shih, 2019), comb. nov., B. gratshevi (Legalov, 2009), and B. rohdendorfi Legalov, 2014 is given. The similarities of the Jurassic weevil faunas from Daohugou, Karatau, Shar-Teg, and Talbragar are discussed. Jurassic Nemonychidae probably developed on Bennettitales and were also associated with gymnosperms of other groups (Cycadales, Ginkgoales, Czekanowskiales, and Coniferales). Species of the genus Belonotaris could be associated with Pterophyllum and other Bennettitales.
Two new species, Succinometrioxena attenuata Legalov et Poinar, sp. n. (Belidae: Oxycoryninae: Metrioxenini) and Tachyerges hyperoche Legalov et Poinar, sp. n. (Curculionidae: Curculioninae: Rhamphini) from Baltic amber are described. Succinometrioxena attenuata Legalov et Poinar, sp. n. is close to Succinometrioxena bachofeni Legalov, 2013 but differs in the larger body size and large punctation of elytra. Tachyerges hyperoche Legalov et Poinar, sp. n. differs from Tachyerges stigma (Germar, 1821) in the scutellum lacking white scales, the larger body size, tibiae with mucro, the distances between points on the pronotum equal to the diameter of the points, and elytral interstriae without hairs. New findings of Glaesotropis (Glaesotropis) weitschati Gratshev et Zherikhin, 1995, Electrotribus theryi Hustache, 1942, Synommatodes patruelis (Voss, 1953) and Caulophilus sucinopunctatus (Kuska, 1992) are recorded. Key to species of the subfamily Cossoninae is given. It is the first record of the genus Tachyerges Schoenherr, 1825 in the fossil state.
A new tribe, Mekorhamphini trib. n., two new genera Mekorhamphus gen. n. and Habropezus gen. n. and two new species (M. gyralommus sp. n. and H. plaisiommus sp. n.) are described from Burmese amber. The new tribe resembles the tribe Mesophyletini but differs from the latter by possessing contiguous procoxal cavities and very wide elytra with regular striae. From the tribe Anchineini, it differs by the contiguous procoxal cavities, precoxal portion of the prosternum elongated, and swollen trochanters. The new taxa can be distinguished from modern Carini by having antennae attached near the middle of the rostrum, an elongated precoxal portion of the prosternum and enlarged trochanters.
