Partial revision of the <i>Acartia</i> subgenus <i>Acartiura</i> (Copepoda: Calanoida: Acartiidae)

Abstract

Abstract Specimens of the Acartia subgenus Acartiura which are closely related to A. clausii Giesbrecht, 1889 were examined from European waters, the east and west coasts of the United States, Japan, Australia, and New Zealand. The species A. ensifera Brady, 1899 and A. simplex Sars, 1905 are redescribed, A, hudsonica Pinhey, 1926 is elevated from subspecific to specific status, and five new species ( A. jilletti, A. lefevreae, A. omorii, A. teclae, and A. tranteri ) are described. A key is given to all known species of Acartiura.
