An unusual mayfly from the Upper Triassic near Dordrecht in the Cape Province of South Africa is described as Xenophlebia optata gen. et sp. nov., and is ascribed to a new family, the Xenophlebiidae, as its sole representative.

Three insects are recorded from carbonaceous shales of Middle Ecca age from Hammanskraal, near Pretoria. Thaumalophora pranotalis gen. et sp. nov., is an aquatic nymph of the Paraplecoptera showing lateral abdominal gills. Sysciophlebia kovacsae sp. nov. is a tegmen of a spiloblattinid cockroach. The third specimen is a small protopsyllidiid nymph. Only three insects of greater age are known from southern Africa.
