Cavichiana Mejdalani et al., 2014 was a formerly monotypic Cicadellinae genus exclusively found in bromeliads from southeastern Brazil. Here a new species is described, diagnosed, and illustrated from Itatiaia National Park, municipality of Itamonte, state of Minas Gerais (Mantiqueira mountain range); specimens were collected on Vriesea spp. (Bromeliaceae). Cavichiana alpina sp. nov. (male holotype in DZRJ) can be recognized by the following combination of features: (1) forewing clavus with basal portion and area along commissural margin orange, remainder of claval area blue (except dark brown apex); (2) corium with large blue area adjacent to claval sulcus, connected to blue area of clavus; (3) distal portion of female and male pygofer not sclerotized; (4) aedeagus with distinct basidorsal lobe and with apex narrowly rounded, not bearing crown of spines; and (5) female sternite VII with deep V-shaped posterior emargination. Notes on the distribution of the genus are provided and C. bromelicola Mejdalani et al., 2014 is newly recorded from southern Brazil.
