Holotype: GIUS 4−584 Mrz./217/26

Diagnoza

Shield−shaped plates usually with three pores in triangular arrangement in their centre, and with nine smaller pores in the marginal zone.

Porównanie

Some of the sclerites have four central pores suggesting some affinity with Palaeocaudina, which occasionally display three central openings. The marginal girdle of Mercedescaudina langeri may have fine pores, as in Staurocaudina dombrowiana, but such specimens are very rare.
