Nazarovella De Wever & Caridroit, 1984: 101 .

TAXON CODE. — 192.

STATUS. — Homonym of the Triassic radiolarian Nazarovella Kozur & Mostler, 1979 (replacement name Raciditor by Sugiyama [2000]); and Junior synonym of Quadricaulis Caridroit & De Wever, 1986 (herein).

DIAGNOSIS. — “Formes à 4 appendices inégaux disposés selon un modèle tétraédrique; 3 sont bien développés, le quatrième est petit. La partie centrale a une forme de tétraèdre globuleux.” ( De Wever & Caridroit 1984: 101).

DIAGNOSIS (ENGLISH TRANSLATION BY J. P. Caulet – RadWorld database). — “Shells with 4 unequal appendices distributed following a tetrahedral pattern; 3 of them are well-developed, the fourth being small. Central part displays a globular tetrahedral shape”.

REMARKS

We treat this genus as a junior synonym of Quadricaulus because the holotype appears to be a broken specimen of Quadricaulus, and the unequal size of the 4 th arm a result of that breakage.
