Description
Summary:Mytilophilus pacificae n.g., n. sp. is described as an endocommensal scuticociliate found on the foot and mantle of the Pacific coastal mussel Mytilus californianus, M. pacificae is distinctive in its buccal apparatus which, while pleuronematine in organization, is dominated by the third membranelle. The third membranelle is a characteristic of the genus and distinguishes M. pacificae from other pleuronematine scuticociliates. The general size, body form, dense ciliation, and nuclear configuration are reminiscent of Peniculistoma mytili , which probably occupies a similar ecological niche in the bay mussel Mytilus edulis . Based on the strong correlation of characters of general morphology, buccal structure and habitat with P. mytili, M. pacificae is placed within the family Peniculistomatidae.
