This is the first record of the occurrence of Guyalna cuta (Walker) (Hemiptera: Cicadidae) in physic nut plants, Jatropha curcas L. (Euphorbiaceae) in the State of Mato Grosso do Sul, county of Dourados. Adults of this insect were observed in the plant canopy during the months of November and December in 2008 and 2009. As there are commercial and experimental plantations of physic nut in Mato Grosso do Sul, further studies about this insect are necessary for preventing eventual damage to crop production.
