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.
