ABSTRACT=<p>The end-Permian mass extinction (EPME) led to a severe terrestrial ecosystem collapse. However, the ecological response of insects to the EPME remains poorly understood. Here, we report a new species assigned to <italic>Chauliodites</italic>, <italic>Chauliodites tongchuanensis</italic> sp. nov. (Grylloblattida: Chaulioditidae), from the Middle Triassic Tongchuan Formation of Shaanxi, northwestern China, and redescribe <italic>Chauliodites fuyuanensis</italic> (<xref ref-type="bibr" rid="B32">Lin, 1978</xref>) from the Lower Triassic Kayitou Formation of Yunnan and <italic>Chauliodites nanshenghuensis</italic> (<xref ref-type="bibr" rid="B32">Lin, 1978</xref>) comb. nov. from the Middle Triassic of Guizhou, southwestern China. Our results show that <italic>Chauliodites</italic> widely distributed after the EPME is probably related to the rise of isoetalean-dominated low-productivity terrestrial ecosystems.</p>
