Taxonomy

Citation: Didymocyrtis tubaria (Haeckel) Sanfilippo and Riedel 1980
Rank: species
Basionym: Pipettaria tubaria
Taxonomic discussion: (Haeckel) 1887; Sanfilippo and Riedel 1980

Catalog entries: Pipettaria tubaria

Original description: Cortical shell ellipsoidal, on both poles distinctly separated from the short conical tubes, the length and breadth of which equal the outer medullary shell. In the equatorial plane arises a circle of four to six short conical protuberances, similar to the polar tubes. Pores subregular, circular, or roundish, scarcely broader than the bars, sixteen to twenty on the half equator. Both medullary shells spheroidal, somewhat compressed in the direction of the two poles (as in fig. 18a).
