The mites listed in the present paper have been collected from July to October 1971 by the junior author and Drs. N. J. J. KOK during their stay in Surinam with financial aid of the Netherlands Foundation for the Advancement of Tropical Research (WOTRO). Mites have been collected occasionally mainly from birds, found dead on the roads, and from captured birds which died in the pet shop “Tropical Wildlife”, Paramaribo. As in many instances the hosts were decayed, few mites could be prepared. The relation of formerly described species to new species clearly shows our poor knowledge of parasites on birds from this region. Most of the species have been described by the senior author (ČERNÝ, 1974a, b, 1975). This paper contains descriptions of new Trouessartia species and a survey of all species found. The taxa are arranged in alphabetical order.
