A new fossil cycad species, Sueria laxinervis , is described from the Upper Cretaceous (Maastrichtian) Quiriquina Formation in Cocholgue, Biobio Region, Chile. The generic assignment is supported by the taeniopterid-type leaf with haplocheilic stomata and sinuate anticlinal walls of leaf epidermal cells, while S . laxinervis clearly differs from the other two described Sueria species in its sparse veins and large epidermal cells. The vascular bundles of the midrib are arranged in an inverted-omega shape, supporting the placement of Sueria in Cycadales.
