First record of Eutrombicula tinami (Oudemans, 1910) (Trombidiformes: Trombiculidae) parasitizing a cat in Brazil.

Chigger mites are ectoparasites of terrestrial tetrapods and can cause dermatitis in the host, known as trombiculiasis. In Brazil, there are 73 species of chiggers; however, cats never have recorded as a host in this country. Here, we report the first record of chiggers parasitizing a domestic cat in Brazil; and a new locality for Eutrombicula tinami (Oudemans 1910) in the Rio Grande do Sul state, Brazil.

Batmanacarus robini, n. gen., n. sp. (Trombidiformes: Trombiculidae) collected parasitizing a ghost-faced bat (Chiroptera: Mormoopidae) from a cave in Trinidad and Tobago.

Trinidad and Tobago, a neotropical country, has 38 reported chigger species. Of these species, 18 were parasitizing bats. Here, we describe a new genus and species parasitizing a ghost-faced bat in this country.
