Watznaueria stenaspis
From Greek stenos, narrow, constricted, and aspis, shield; referring to the very narrow distal shield surrounding the broad, closed central area.
On the distal side, the extinction angle in the shields is approximately 80°. This cannot be directly measured in the tube cycles due to the oblique orientation of their constituent segments; however, the apparent angle between extinction directions in the tube cycle is approximately 76°, corresponding to an obliquity of approximately 14°.
