Lejeunecysta spectabilis
Lejeunecysta spectabilis He Chengquan, 1991
Holotype: He Chengquan, 1991, pl.1, fig.40
Age: Middle Eocene
Description from He Chengquan, 1991, translated by Suning Hou, 07-01-2019
Description: Cyst dorsal ventral flatened, outline transversally elongated pentagonal, width greater than the length. upper cyst lid like, with a papillary small convex; Lower cyst earthen bowl or mortar shape, tail damaged. Waist outward plump, lateral horns formed by the cingulum. Cingulum significant, narrow, annular, its edge is marked by the high septa, the septa height is up to 7μm, after the flatened it forms a clear ring at the equator. Sulcus lacking. Cyst wall single layer (non-stratification), the surface is slightly granular-slightly coarse. Archeopyle clear, intercalary, outline trapezoidal, its size is 16μm × 30μm, located under the top. Operculum completely separated, preserved in situ. The cyst length is more than 7 5μm (specimen incomplete), width 106 μm.)
Note: Although the tail of this specimen is not completely preserved, but the clear archeopyle and cingulum provide significant structure features for taxonomy.
