Sanniopileus, Dumitrica & Zügel, 2003

Dumitrica, Paulian & Zügel, Peter, 2003, Lower Tithonian mono- and dicyrtid Nassellaria (Radiolaria) from the Solnhofen area (southern Germany), Geodiversitas 25 (1), pp. 5-72 : 43-44

Genus Sanniopileus n. gen.

TYPE SPECIES. — Sanniopileus stultus n. gen., n. sp.

ETYMOLOGY. — From the Latin sannio: fool; and pileus: cap, pointing out the resemblance to a fool’s cap. Masculine gender.

DIAGNOSIS. — Test dicyrtid with cephalis having all spines of the initial spicule (A, V, Lr, Ll, lr, ll) extend- ed externally into long three-bladed spines. D absent. The two L steeply inclined, attached to the thoracic wall. Thorax conical, widely open distally, with surface covered by transverse ridges.

REMARKS

Sanniopileus n. gen. differs from Foremanellina Dumitrica, 1982 in that the two L spines are steeper inclined downward forming longitudinal ribs along the thorax. Recoaroella Dumitrica, 1982 , Riedelius De Wever, 1982 , and Hilarisirex Takemura & Nakaseko, 1982 differ from Sanniopileus n. gen. by having at least a part of all four lateral spines lying in the thoracic wall. Sanniopileus n. gen. is the youngest member of the family Foremanellinidae , but by its morphology it cannot be derived from the Middle Jurassic genera Hilarisirex or Diceratigalea Takemura & Nakaseko, 1982 , which are the youngest representatives of the family known so far. The morphology of its thorax, with transverse ridges and triangular or quadrangular pores, is closer to the Lower Jurassic genus Riedelius De Wever, 1982 .
