Holotype. Several specimens are deposited in the Zoological Museum of the Ernst Moritz Arndt University, Greifswald, and the Museum für Naturkunde, Berlin, Germany ( Athersuch & Whittaker 1982; Athersuch et al. 1989). However, none of them is designated as the holotype.

Type locality. Santa Lucia, Bay of Naples, Italy ( Müller 1894).

Material. 109 specimens (MP-612 and MP-747).

Figured specimens. CP-473, CP-475, CP-476, CP-477, CP-478, CP-479 and CP-480 (carapaces); CP-481 (valve) ( Tab. 5).

Geographic and stratigraphic distribution. Bay of Naples, Italy ( Müller 1894); environments of Roscoff, Northwest France ( Vos 1957); Adriatic Sea, Italy ( Bonaduce et al. 1975); Scotland, South England, French Atlantic coast and Mediterranean Sea until Cyprus ( Athersuch et al. 1989); possibly São Pedro-São Paulo Archipelago, Brazil; Recent.

Remarks. Subgeneric diagnosis follows Maddocks (1969b), as the general shape of the carapace fits into the classification system proposed for Propontocypris by this paper. The diagnosis at specific level is based on Müller (1894), although the posterior end of the carapaces studied here is slightly more acuminate.
