Four New Species and One New Record of Stromboscerini (Coleoptera, Curculionidae, Dryophthorinae) from China

This study reports one genus newly recorded from China and four new species of the weevil tribe Stromboscerini. The genus <i>Dexipeus</i> Pascoe, 1885, is recorded in China for the first time, with one new species described: <i>Dexipeus tengchongensis</i> sp. nov. Additionally, three new species of <i>Tasactes</i> Faust, 1894, are recognized and diagnosed: <i>T. biunciatus</i> sp. nov., <i>T. liangi</i> sp. nov., and <i>T. sulcatus</i> sp. nov. For all new species, detailed morphological descriptions, diagnostic illustrations, and habitus pictures are provided. Two updated identification keys are presented. High-resolution pictures of the type specimens of the previously described Chinese species <i>Allaeotes niger</i> He, Zhang & Pelsue, 2003, and <i>Synommatoides scutellatus</i> He, Zhang & Pelsue, 2003, are also provided for future taxonomic research.
