Six new species of Margattea Shelford, 1911 (Blaberoidea, Pseudophyllodromiidae, Neoblattellini) from China.

Six Margattea species are established and described: three are cryptic species, namely, M.parabisignata Li & Che, sp. nov. , M.semicircularis Li & Che, sp. nov. , and M.forcipata Li & Che, sp. nov. They are distinguished from known species M.bisignata , M.spinifera , and M.paratransversa by their male genitalia with the aid of molecular species delimitation method (ABGD) using COI as the molecular marker. The other three new species are M.pedata Li & Che, sp. nov. , M.undulata Li & Che, sp. nov. , and M.bisphaerica Li & Che, sp. nov. Morphological and genitalia photographs of these new species of Margattea , as well as a key to the species of Margattea from China, are provided.
