TYPE MATERIAL ­ female holotype, 30 female, 6 male paratypes, from Eugenia

uniflora L. ( Myrtaceae ), "pitanga", Piracicaba, São Paulo, Brazil (22° 40' 32" S, 47° 38' 00" W), 08 July 2002, coll. L.C. Lofego, on 10 microscopic preparations.

RELATION TO HOST ­ vagrant on the upper leaf surface.

ETYMOLOGY ­ The specific designation kleithria is a Greek word meaning keyhole and refers to the inverted figure formed by admedian lines on the prodorsal shield.

REMARKS ­ Dorsum of tibia I in the female of the new species with a small solenidion­like structure inserted near the base of the tibial seta. A similar structure was described by Flechtmann (1999) for Shevtchenkella gnatholoba .
