Holotype: W. Wetzel, 1952, pl.A, fig.4
Locus typicus: Kiel district, Germany
Stratum typicum: Paleocene
Translation W. Wetzel: Sarjeant, 1984

Original diagnosis: W. Wetzel, 1952, p. 403
Some specimens, which in other attributes do not differ from the typical species, are distinguishable from it in that the distal ends of the processes develop into two sideways-directed prongs (and thereby suggest more the usual structure of hystrichosphere processes). Also no noteworthy curving of the processes was observed.
