Phelodinium magnificum (Stanley, 1965) Stover and Evitt, 1978. According to Stanley (1965), this species has a large, pentagonal pericyst with a wall that is smooth or covered with small irregularly placed spines and is often longitudinally wrinkled. Apical horn 5-10 µm long, antapical horns about 5-10 µm long, with left slightly longer than right. Endocyst completely fills pericyst. Girdle well developed, about 8 µm wide. Furrow about 15 µm wide and bordered by more or less frilled border. Archeopyle six-sided with posterior side considerably longer than the anterior side. Size: Length 120-135 µm, width 100-115 µm.

Original description: Stanley, 1965, p.218: Deflandrea magnifica
Outer cyst large, pentagonal in dorso-ventral view; length 120-135 µm overall; width 100-115 µm; outer cyst wall smooth to covered with small irregularly placed spines; wall thin and often longitudinally wrinkled. Apical horn 5-10 µm long; antapical horns about 5-10 µm in length with left horn slightly longer than the right one; antapical horns tend to slightly diverge from each other. Inner cyst completely fills the outer one. Girdle well developed, width about 8 µm. Furrow about 15 µm wide and is bordered by a more or less frilled border. Archeopyle six-sided with posterior side considerably longer than the anterior one.

Deflandrea magnifica is differentiated from D. pannucea by its distinctly larger size and its shorter antapical horn.
