Trouessartia quarta was originally described from the barn swallow, Hirundo rustica , in South East Asia (Malaise, Thailand) ( Gaud & Atyeo 1987). These authors noted that it does not occur on the same host individuals together with T. microcaudata Mironov, 1983 , a species of the minutipes group widely distributed on this host in the Old World, from Europe to South East Asia ( Mironov 1983, 1996; Gaud & Atyeo 1987). The latter authors suggested that T. quarta is restricted to the Indo-Malayan region and considered a single specimen of this mite found on a museum skin of H. rustica from Cuba as accidental contamination. Our study of samples from Canada and additional museum material shows that T. quarta is also widely distributed on H. rustica in the New World, from Canada to Argentina.
