simplex Priesner, 1924

(Figs 40, 75, 107, 143)

Originally described from Mexico, but recorded from Guatemala (Mound & Marullo 1996), one female of this dark brown thrips has been recorded from Orchidaceae flowers in São Paulo (Monteiro 1999). The fore wings are almost uniformly brown, scarcely paler at the base, and setae S1 on abdominal tergite IX are little more than half of S 2 in length. Ocellar setae pair III are rather short, 25–35 microns long, and the pronotum has almost no sculpture medially apart from a weak longitudinal ridge.
