Ixodes philipi: Redescription of Female and First Description of Male, with Records from Streaked Shearwater in Japan (Acarina: Ixodidae)

Ixodes philipi Keirans & Kohls, 1970 is so far known only from two female specimens taken from the streaked shearwater, Puffinus leucomelas (Temminck, 1835) [presently Calonectris leucomelas (Temminck, 1835)], or the madeiran storm-petrel, Oceanodroma castro (Harcourt, 1851), in Japan. We redescribe the female and describe the male of this species. We used nine adults (four males and five females) taken from the bodies of C. leucomelas and/or soil samples of their nest burrows in Japan, indicating that C. leucomelas is the main natural host bird of I. philipi.
