A new genus and species of the grylloblattid family Chaulioditidae, Iphikozulu kwayayaensis Aristov & Mostovski, gen. et sp. n., is described from the Lopingian locality of KwaYaya in KwaZulu-Natal, South Africa. This is the first record of the Chaulioditidae in Gondwanan deposits. The genera Triadosialis Handlirsch, 1906, Protomia Aristov, 2004 and Miralioma Aristov, 2004 are transferred to the family Chaulioditidae, and the genus Kargalella Martynov, 1937 is transferred to the Liomopteridae. Neoliomopterum picturatum Riek, 1976 from the Lopingian locality at Emakwezini Railway Station in KwaZulu-Natal is redescribed and transferred from Grylloblattida incertae sedis to the family Liomopteridae. The subfamily Kargalellinae Aristov, 2004 is synonymised under Liomopteridae Sellards, 1909.
