Tanochenia nov. gen., a new generic name for the radiolarian species Stylotrochus asteros Tan & Chen, 1999 Tanochenia nov. gen., un nouveau nom générique pour l'espèce de radiolaire Stylotrochus asteros Tan & Chen, 1999

The structural study of several Quaternary specimens of the radiolarian species Stylotrochus asteros Tan and Chen, 1999 proves that this species does not belong to this genus or to other Cenozoic genera so far known. This species has a large lenticular lattice cortical shell with one face convex and the other one concave or flat, and an initial skeleton inside it consisting of a small tumour-shaped spongy structure attached to the convex side. Given these peculiarities of this species, the author erects for it the genus Tanochenia nov. gen. © 2014 Elsevier Masson SAS. All rights reserved.
