A new status is proposed for the genera Glabromyzus Richards, 1960 and Juncomyzus Hille Ris Lambers, 1965, which are now treated as subgenera of Carolinaia Wilson, 1911. The relationship between Carolinaia and Utamphorophoro Knowlton, 1947 is discussed. The new name C. (C.) tissoti is given for Carolinaia rhois Tissot, 1928 nec rhois Monell, 1879. The species known as Juncomyzus rhois (Takahashi, 1924) becomes C. (J.) japonica (Takahashi, 1961). The oviparous female of C. (G.) schlingeri, C. (J.) japonica, and C. (J.) nigra are described as well as the alate viviparous female and the male of the last species. Four keys are given for the apterous and alate living on Rhus and on Monocotyledones plants. The following 4 new species are described: C. (C.) floridensis, from USA, C. (G.) quadnaui from Canada, C. (G.) corazonensis and C. (C.) setariae both from Mexico. The host plants, life cycle and distribution of the 17 species of Carolinaia are discussed.
