Major infestations of the flat mite species Raoiella indica Hirst have been reported from the Caribbean islands of Dominica, Martinique, and Saint Lucia. Specimens from these localities were compared with type material from the British Museum and the Philippines, leading to a redescription of the genus. While little is known about the bilogy of this mite, its recent appearance in the Caribbean in both commercial coconut and banana plantations has raised concerns about its potential as an invasive pest.
