• Abstract: A male lectotype of Tettigonia vitripennis Germar deposited in the allegedly lost Germar Hemiptera collection, but recently found in the Ivan Franko National University (Ukraine) is herein designated and assumed to be erroneously labeled from Brazil. Homalodisca vitripennis is considered a senior synonym of Tettigonia coagulata syn. nov., and should therefore used as the new scientific name for the glassy-winged sharpshooter, a major vector of the bacterial Pierces disease of grapes, phony peach disease, plum leaf scald, and oleander leaf scorch in southern US and northern Mexico. Furthermore, due to a misidentification of the previous type-species of Homalodisca Stl by the subsequent designator, Tettigonia vitripennis is herein fixed as the new type-species of this economically important genus. The previously designated type-species of Homalodisca, Cicada triquetra F., is herein transferred to Propetes Walker. Propetes triquetra comb. nov., represented previously only from an unknown locality in South America, is herein newly recorded from Brazil (Mato Grosso and Par states).
