Pickelhaube furtiva

Cruciplacolithus furtivus Roth, 1983

Cretarhabdus? delicatus Applegate, Covington & Wise in Covington & Wise 1987; pl. 16, Fig. 4 (holotype); non-Pl. 16, Fig.3.

Species of Pickelhaube with a very broad, strongly concavo-convex proximal plate and a narrow collar surrounding a central area spanned by an axial cross that supports a distal process and lateral bars.

Optical properties consistent with those of Pickelhaube.
