This paper treats Chinese species of Elachertus Spinola. Twenty-three valid species are recognized, and a key to species groups and another to species are provided. Nine species are newly recorded from China: E. auripes (Girault), E. charondas (Walker), E. fenestratus Nees, E. inunctus Nees, E. isadas Walker, E. lateralis (Spinola), E. pulcher (Erdös), E. sobrinus (Girault and Dodd), and E. simithorax (Girault). Fourteen new species are described and compared with closely related species: E. flavimaculatus, E. longiramulus, E. ater, E. petiolifuniculus, E. divergens, E. flavifuniculus, E. scutellaris, E. obliquus, E. oligiramus, E. parallelus, E. sulcatus, E. pilifer, E. ramosus, and E. varicapitulum. Among Chinese species, ten can be placed in 2 of Bouček's (1988) species groups, while another 13 are classified into 5 newly proposed groups. New hosts and distributional records are provided. http://www.sinica.edu.tw/zool/zoolstud/40.4/317.pdf.
