Abstract

A new species of stem Orthoptera, namely Phtanomiamia gui gen. et sp.nov., is described from the Pennsylvanian Xiaheyan locality in China.Despite the intensive collecting efforts undertaken at this locality, asingle forewing was recovered. It shares with the “lobeattid” Miamia spp. twopeculiar traits, namely a broad ScP–R/RA area and a very early branchingof CuA + CuPa. On the other hand, it displays a free portion of CuA (betweenits divergence from M + CuA and its fusion with CuPa), a trait allowingexclusion of the new species from Miamia, to which it is most likely very closelyrelated.
