A redescription of Pseudodiaptomus salinus (Giesbrecht, 1896) and a new species from the Arabian Sea (Copepoda, Calanoida, Pseudodiaptomidae)

Many species of Pseudodiaptomus are known from the Indian Ocean. However, only two species have been reported from the Red and Arabian Seas. A review of P. salinus (Giesbrecht) from collections near Kuwait and Pakistan in the Arabian Sea revealed differences from Red Sea material. Further study proved the existence of a new species Pseudodiaptomus arabicus n.sp.
