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.
