Twelve larvae of unidentified species of Odontacarus Ewing, 1929 (Acari: Leeuwenhoekiidae) were found parasitising an adult male whip spider Charinus brasilianus Weygoldt (Charinidae) in Santa Teresa, mountainous region of Espírito Santo state, southeastern Brazil. These larvae occurred in the intersegmental membrane of prosoma and legs. This is the first report of ectoparasitic mites infecting a charinid whip spider and the first record of leeuwenhoekiid mites parasitising an invertebrate host. We suggest that future studies are essential to understand the reasons why these events of parasitism are so rare in the order Amblypygi.
The present paper comprises a systematic survey of the chigger mites (Acarina: Leeuwenhoekiidae) collected from bats and bat guano in Cuban caves in 1965-1985. Wagenaaria similis is recorded for the first time in Cuba. The first hosts known for Ischnothrombium diploctenum are noted. Antrohoekia inexpectala, g.n., sp. n., a parasite of bats, is described.
