ABSTRACT The sharpshooter genus Cavichiana Mejdalani et al., 2014 included so far only two species of about 6-8 mm in length C. bromelicola Mejdalani et al., 2014 (type species) and C. alpina Quintas et al., 2020. Both are bromeliad specialists from southeastern and southern Brazil. Here a third species, C. caelivittata sp. nov., is described and illustrated based on males and females from the Serra dos Órgãos massif in state of Rio de Janeiro, southeastern Brazil. The new bromeliad specialist can be readily distinguished from the previously known species by the dorsum with a pair of broad whitish-blue stripes, each one extending from antennal ledge over lateroposterior area of crown, lateral portion of pronotum, basal portion of clavus, and forming an elongate arc on corium up to outer margin of first apical cell; the aedeagus bears a dorsoapical digitiform lobe directed posterad. A key to the three species, based on the coloration and morphology of the aedeagus, is provided. In addition, the distribution of C. bromelicola is discussed; it is suggested that the trade of bromeliads as ornamental plants is causing the spread of this species to various urban and suburban areas of southeastern Brazil.
