Paralesleya perforata gen. et sp. nov., a new ostracod species from the Latest Jurassic of Northwest Europe

Abstract. A Late Jurassic ostracod species, reported earlier under the name of Indet. Gen. sp.206, is formally described and placed in the new genus Paralesleya. Its known distribution, southern Sweden and Denmark, is extended by new reports from southern England (Dorset), northern France (Boulonnais), and the Dutch Central North Sea Graben. The species has stratigraphic value and contributes to more precise correlations between the cliff sections on either side of the Channel.
