Van Veen (1936b) found the ostracod species Krausella minuta Triebel, in deposits of the uppermost Maastrichtian from the Valley of the Jeker, South Limburg, The Netherlands. Investigation has shown that Triebel never published any data on this species, so the name Krausella minuta has to be rejected, being a nomen nudum.
In the boreholes of Kallo (27 E 148) and Knokke (11 E 138), in the northwestern part of Belgium, a related, yet undescribed species occurs, for which the name Cardobairdia triebeli sp. nov. is proposed. This taxon was found in deposits of mainly Lower Campanian age. Another new species, Cardobairdia rectimarginata, is described from the Campanian in the Knokke Borehole.
The specimens of Cardobairdia minuta from the Cenomanian from southern England belong to a new species, defined here as C. cenomanensis.
