Cypridina olimoblonga Kornicker, a new name for the junior primary homonymCypridina oblonga Jones & Kirkby, 1874, and clarification of its authorship, and the authorship of the Palaeozoic genera Cypridinella, Cypridellina, Sulcuna, Rhonibina, and Offa (Crustacea : Ostracoda)

A. new name, Cypridina olimoblonga Kornicker, is proposed for the junior pr imary homonym Cypridina oblonga Jones & Kirkby 1874 (non C oblonga Grube 18 59), type species of Sylvesterella Kornicker & Sohn 2000. Authorship of the replaced species, as well as other species described as new in "A Monograp h of the British Fossil Bivalved Entomostraca from the Carboniferous Format ions" (1874), should be attributed to I Rupert Jones & James W. Kirkby, not to Jones, Kirkby & Brady. It is concluded that the correct authorship of t he genera Cypridinella, Cypridellina, Sulcuna, Rhombina, and Offa should be attributed to T Rupert Jones.
