| Summary: | 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.
