A new disaccate pollen grain from the Triassic of Argentina

Cedripites tectus sp. nov., from the Middle to Late Triassic Rincon Blanco Group of San Juan province, west of Argentina, is a haploxylonoid to slight ly dyploxilonoid disaccate pollen grain with a longitudinally oval amb. The corpus is almost rhombic in polar view and trapezium-like in off-polar com pression. The sacci show a strong distal inclination and merge gradually wi th the corpus, encompassing a narrow cappula about one tenth of the corpus breadth. A brief discussion on Cedrus-like fossil miospores validates the u sage of Cedripites Wodehouse.
