Taxonomy

Citation: Streblacantha Haeckel 1887

Rank: genus

Basionym: Streblacantha

Taxonomic discussion: Has been assigned to Pyloniidae, here assigned to Streblonidae following new classification being developed by Suzuki & co-workers

Catalog entries: Streblacantha

Original description: Streblonida with simple, spherical, subspherical, or lentelliptical primordial chamber, beginning the screw-like series of spirally ascending chambers. Surface covered with radial spines.

The genus Streblacantha differs from the nearly allied Streblonia only in the covering of radial spines, and bears therefore the same relation to it as Hastigerina has to Globigerina amongst the similar calcareous Polythalamia.
