    Abstract

    A Late Ordovician (latest Eastonian) fauna from the Gunningblad Formation near Gunningblad, central-west New South Wales, includes a new cybeline belonging to the genus Sinocybele Sheng, 1974. Sinocybele thomoasi sp. Nov. is most closely related to Late Ordovician (Caradoc) species from Kazakhstan that were formerly assigned to Koksorenus Koroleva, 1992, a junior synonym of Sinocybele. Sinocybele is distributed in Middle Ordovician (Darriwilian) to Upper Ordovician (lower Ashgill) strata on the North and South China block, the Sibumasu terrane, the Yining-Kawabulak-Beishan terrane, Tarim, Central Asian terranes in Kazakhstan and Uzbekistan, and in the Taurides terrane of turkey. Its presence in the island-arc complexes of New South Wales adds another characteristic component of the Eokosovopeltis-Pliomerina fauna to the Australian biota.
