Detailed analysis of breviaxial, tricolporate pollen from the Australian Upper Cretaceous reveals that Forcipites Dettmann & Jarzen, 1988, Gambierina Harris ex Stover & Partridge, 1973, emend., and Battenipollis gen. nov. are distinct in wall structure and aperture architecture from the Normapolles and Probrevaxones of the Northern Hemisphere. The parental source of the southern Normapolles-like pollen ranged across the Austro-Antarctic landmass during latest Cretaceous time, but probably evolved later than and independently of the northern taxa. Battenipollis is proposed for transcolpate, breviaxial pollen, and Gambierina is herein emended.
