Dumitrica, Paulian & Zügel, Peter, 2003, Lower Tithonian mono- and dicyrtid Nassellaria (Radiolaria) from the Solnhofen area (southern Germany), Geodiversitas 25 (1), pp. 5-72 : 31-32

Saitulpus sp. aff. S. retrospina n. sp. ( Fig. 17E )

MATERIAL EXAMINED. — One specimen from sample Mue 22.

DIMENSIONS ( IN µM). — Length of cephalis 45, of feet 40, of apical horn 25, width of cephalis 60.

REMARKS

The species, from which we have only one specimen, differs from S. retrospina n. gen., n. sp. by the lack of recurved spines on feet and apical horn. One foot may have one or two spines beyond the verticil. Unfortunately, the specimen is coarsely recrystallized so that the details of the spines are not perfectly preserved.
