The current classification system of the family Gryllacrididae primarily relies on morphological characteristics, with limited molecular studies conducted. In this study, we sequenced five genes (COI, COII, Cytb, 18S, and 28S) from a total of 46 gryllacridid individuals mainly from China. Subsequently, we utilized both the maximum likelihood method and the Bayesian inference method to construct a phylogenetic tree, aiming to elucidate the phylogenetic relationships within Gryllacrididae from China. Our results indicate that the genera Phryganogryllacris Karny, Capnogryllacris Karny, and Eugryllacris Karny are not monophyletic. Thus, we redescribe these genera, resurrect two genera (Marthogryllacris Karny stat. resurr. and Borneogryllacris Karny stat. resurr.), erect six new genera (Dracogryllacris gen. nov., Magnigryllacris gen. nov., Radigryllacris gen. nov., Sericgryllacris gen. nov., Bicornisgryllacris gen. nov., and Tenuigryllacris gen. nov.), and described two new species (Tenuigryllacris huanglianensis Li, Yin & He sp. nov. and Tenuigryllacris yingjiangensis Li, Yin & He sp. nov.). Besides, subgenus Bianigryllacris Cadena-Castañeda is a synonym of Apterolarnaca Gorochov.
