Sympatric Two-species Infestation by Rhizocephalan Barnacle Parasites in the Spider Crab Pugettia aff. ferox Ohtsuchi & Kawamura, 2019 from Peter the Great Bay (Northwestern Sea of Japan).

ABSTRACT: Sympatric two-species infestation by rhizocephalan parasites in the spider crab Pugettia aff. ferox Ohtsuchi & Kawamura, 2019 (Brachyura: Epialtidae) was investigated in the Vostok Bay (Peter the Great Bay, northwestern Sea of Japan). Morphological and molecular analyses showed that this crab was infested simultaneously by Sacculina pugettiae Shiino, 1943 and Parasacculina pilosella (Van Kampen et Boschma, 1925) (Cirripedia: Rhizocephala). Sacculina pugettiae was found in the northwestern Sea of Japan for the first time. The two rhizocephalan species are clearly distinguishable by the morphology of their external cuticles, the shape and position of their receptacles, and the structure of their colleteric glands. Retinacula are present in the mature extern
