Cypridea conjugata Krömmelbein & Weber, 1971

Fig. 9, 9a–c

1971 Cypridea conjugata n. sp. —Krömmelbein & Weber, p. 14–15, pl. 1, figs 4–5.

Diagnosis: A medium-sized species of Cypridea (carapace on average somewhat over 1mm long) with the following peculiarities: rostrum strong, fairly straight, with the tip pointing steeply backwards and downwards and extending beyond the ventral margin. Sculpture is remarkable: longish pore dimples on the whole shell outer surface, separated by slight ridges which run more or less parallel to the outer margins. There are also nodes; a thorn-like node in the eye region and in a mid-dorsal position; smaller, more rounded, less frequently more or less tapering nodes, scattered on the shell’s outer surface, more or less clearly ordered in rows (a row of four on the posterior valve surface, a row of partly joined together nodes along the length of the ventral margin), as well as two or three little nodes above the two spine-like nodes.

Holotype: Left valve, BfB 7772.

Paratype: Right valve, BfB 7773.

Dimensions: Holotype, length 1.03mm, height 0.67mm (no width given in original paper).
