A total of 81 Tyraniidae birds were examined, 80 Pitangus
sulphuratus (Linnaeus, 1766) (Great kiscadee),
and one Machetornis rixosa (Vieilot, 1819)
(Cattle tyrant), for collection of nasal mites, which were identified
as Ptilonyssus spinosus (Brooks & Strandtmann, 1960BROOKS, DL. and STRANDTMANN, RW., 1960. The Nasal Mites
(Acarina) of Some West Texas Flycatchers (Tyrannidae).

longisetosae (Hyland,
1961HYLAND, KE., 1961. Sternostoma longisetosa, a new species of nasal
mite from the eastern kingbird with notes on the occurrence of Tyranninyssus
spinosus Brooks and Strandtmann in southern Michigan (Acarina:
Rhinonyssidae). Acarologia, vol. 3, p. 279-284.) (Rhinonyssidae). This finding characterises the
first report of P. spinosus and S.
longisetosae in P. sulphuratus, and the first
record of P. spinosus in M. rixosa, and expands the geographic
distribution of these species. It is the first occurrence of S.
longisetosae in the Neotropics, and the first citation of
P. spinosus in the state of Rio Grande do Sul, Brazil.
