Abstract
The Xiaheyan locality is providing abundant material on one of the earliestinsect faunas. The most common species are comparatively remote relatives ofOrthoptera (grasshoppers, crickets and katydids), belonging to theArchaeorthoptera 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 conclusivelyassigned to Panorthoptera. It therefore represents the second occurrenceof the group at this locality. The new species displays a distinctivecombination of character states, adding to the knowledge of a number of UpperCarboniferous Panorthoptera whose relationships are poorly understood.
