The new species Microdinium avocetianum from the Tithonian (Upper Jurassic) of Australia is described. It is a small partiform gonyaulacalean cyst with a distinctive paratabulation style, dark autophragm and low, irregularly denticulate crests. The species may be relatively prominent in the late Tithonian (Pseudoceratium iehiense Range Zone) of the Timor Sea, offshore northwestern Australia and the Carnarvon Basin, offshore Western Australia.
