A new species of Clausidium Kossmann, 1874 (Crustacea, Copepoda, Cyclopoida, Clausidiidae) associated with ghost shrimps from Iran

Abstract

Abstract A new species of the Clausidium Kossmann, 1874 copepods is described, illustrated and provided by Confocal Laser Scanning Microscope photo on the basis of specimens from the gill chamber of Callianidea typa H. Milne Edwards, 1837 from the Iranian coast of the Persian Gulf. Clausidium persiaensis sp. nov is unique in the possession of a fine spine on endopod-1 of the antennae, large blade-like setae with an acute tip on P1, and the shape of P5 and the anal somite. The new species extends the group distribution into the northwest Indian Ocean and represents the first records of the genus in Iran.
