A new species of stem Orthoptera, namely Ph-tanomiamia gui gen. et sp. nov., is described from the Penn-sylvanian Xiaheyan locality in China. Despite the intensive collecting efforts undertaken at this locality, a single forewing was recovered. It shares with the "lobeattid" Mi-amia spp. two peculiar traits, namely a broad ScP-R/RA area and a very early branching of CuA + CuPa. On the other hand, it displays a free portion of CuA (between its divergence from M + CuA and its fusion with CuPa), a trait allowing exclusion of the new species from Miamia, to which it is most likely very closely related.
