Impagidinium taiwanianum Shaw Chenglong, 1999b, p.170-172, figs.28-36.
Holotype: Shaw Chenglong, 1999b, figs.28-30. Age: Eocene.
Original description (Shaw Chenglong, 1999b)
Cyst of intermediate size, spherical to subspherical; 78-95µm wide; autophargm thick (c. 2 µm) smooth, bearing low, solid straight parasutural septa. Precingular archeopyle, distinct, small, length and breadth usually less than one-third diameter of cyst. Second and third apical paraplates large; first fourth apical paraplates relatively narrow and elongate. Paratabulation well defined; no apparent subdivision into sulcal paraplates.
Dimensions holotype: 92µm long, 83µm wide, septa 2 µm thick.
Dimensions overall: 78-95 µm long, 59-85 µm wide, septa 1.5-3 µm thick (n=14).
Derivation of name: The specific epithet taiwanianum is derived from the name of the type locality.
