Radiolaria - Spumellaria - Pantanelliidae
Original description: Test spherical to ellipsoidal with two triradiate polar spines. Meshwork of test comprised of numerous concentric subspherical rings of pentagonal and hexagonal pore frames anchoring to pillar-like structure at pore frame vertices. Size of pore frames decreasing gradually toward center of spherical test.
Original remarks: Pseudopantanellium n. gen., has super&64257;cial
resemblance to Pantanellium Pessagno (1977b). However, Pseudopantanellium can be distinguished from
Pantanellium by having a series of concentric layers of
pentagonal or hexagonal pore frames rather than consisting only of a cortical shell and a medullary shell.
Etymology: From the Latin pseudo false, and Pantanellium.
If no rank is listed, the taxon is considered an unranked clade in modern classifications. Ranks may be repeated or presented in the wrong order because authors working on different parts of the classification may disagree about how to rank taxa.
