Ten atrypide taxa, belonging to the superfamilies Atrypoidea, Lissatrypoidea, and less certainly the Glassioidea, are described from the late Wenlock or earliest Ludlow to Pridoli of the Yass Syncline. New taxa are Gracianella (Gracianella) kausi yassensis subsp. nov. and Spirigerina mitchelli sp. nov. On the basis of more abundant material from the Molong district, it is concluded that Atrypoidea (Atrypoidea) angusta Mitchell & Dun, 1920 is synonymous with the type species Atrypoidea (A.) australis (Dun, 1904). The single Pridoli species is comparable to Lissatrypa lenticulata Philip, 1962 from the Lochkovian of Victoria and central New South Wales, here referred to Meifodia Williams, 1951.
