Two new species of Bradyidius with notes on B. armatus Giesbrecht (Crustacea, Copepoda: Aetideidae)
E.L. Markhaseva
Abstract. Bradyidius subarmatus sp. n. from the Norwegian coast and Bradyidius curtus sp. n. from the North West Pacific are described. The most characteristic feature of B. subarmatus is the setation of the first antennal exopodal joint, and of B. curtus the short posterior points of the last thoracic segment. B. armatus Giesbrecht, 1897, which is very close to B. subarmatus, is redescribed and its synonymy discussed.
