title: New record of the planktonic copepod Oithona davisae Ferrari and Orsi in the Black Sea with notes on the identity of “Oithona brevicornis”
abstract: Specimens of small (< 1 mm) cyclopoid copepods of the genus Oithona were collected from Sevastopol Bay and an offshore area of the Black Sea. On the basis of a combination of characteristics such as those in the maxillule and the genital double-somite, the specimens were identified as O. davisae Ferrari and Orsi, 1984. The identity of “O. brevicornis” that was reported in the Black Sea and the possible origin of O. davisae in the Black Sea are discussed.
