Abstract. The Xiaheyan locality is providing abundant material on one of the earliest insect faunas. The most common species are comparatively remote relatives of Orthoptera (grasshoppers, crickets and katydids), belonging to the Archaeorthoptera nec Panorthoptera (the latter including crown Orthoptera). We establish the genus Sinogerarus gen. nov. to accommodate a new, rare species, S. pectinatus spec. nov., which can be conclusively assigned to Panorthoptera. It therefore represents the second occurrence of the group at this locality. The new species displays a distinctive combination of character states, adding to the knowledge of a number of Upper Carboniferous Panorthoptera whose relationships are poorly understood.

Short summary
A new fossil species relative of grasshoppers, crickets and katydids is described from the famous Xiaheyan locality (China). Compared to other species recovered from these 310-million-year-old strata, Sinogerarus pectinatus gen. and spec. nov. is likely most closely related to extant forms. The group it belongs to will become preeminent a few million years later but is very rare at Xiaheyan.
