Material examined: 7 males and 11 females (ZISP 7458–7475) from Hirundo rustica Linnaeus, 1758 ( Passeriformes : Hirundinidae ), CANADA, Manitoba, Winnipeg, 7 June 1999, coll. T.D. Galloway.

Trouessartia appendiculata was originally described from the sand martin, Riparia riparia (Linnaeus) (Berlese 1886) . However, this record was probably the result of accidental contamination or incorrect host identification, because this mite species is specific to swallows of the genus Hirundo ( Santana 1976; Gaud & Atyeo 1986). At the same time, the appendiculata species group is represented on R. riparia by T. piscicauda Gaud, 1957 (see below), which is unmistakably different from T. appendiculata by the structure of the terminal lamellae in males ( Figs. 16A versus D). Trouessartia appendiculata was reported from H. rustica almost worldwide, in Europe, Africa, South East Asia and North America ( Canada, Cuba), and also from H. smithi (Leach) in Cameroon ( Gaud & Till 1961; Černý 1967; Santana, 1976; Gaud & Atyeo 1986; Galloway et al. 2014).

The reports of this mite from Cecropis senegalensis (Linnaeus) and Psalidoprocne pristoptera petiti Sharpe & Bouvier in Cameroon ( Gaud 1957; Gaud & Mouchet 1958) were proven to be misidentifications ( Gaud & Atyeo 1986); the reports from Pseudhirundo griseopyga (Sundevall) in Zair ( Gaud & Atyeo 1986) and Petrochelidon pyrrhonota (Vieillot) in the Wrangel Island, Russia ( Dubinin 1952), also are highly probable misidentifications.
