The tribe Alysiini Leach is a diverse group comprising 78 genera and approximately 1,600 valid species worldwide. In China, 27 genera and over 140 species have been recorded to date. The genera Dapsilarthra Förster, Grammospila Förster and Heterolexis Förster are small groups within the tribe Alysiini, each containing only seven or eight valid species worldwide. These genera have been rarely studied in China, with Heterolexis represented by only one previously recorded species and Dapsilarthra and Grammospila each by three species. This study reviews Dapsilarthra , Grammospila and Heterolexis . Four new species are described from China: Grammospila angustisulcata sp. nov., Dapsilarthra spiraculata sp. nov., D. parallela sp. nov. and D. aurantia sp. nov. Three species of Heterolexis are newly recorded from China. Keys to species of these genera are provided. The morphological variation of the Chinese specimens is described and illustrated.
