Abstract
CavichianaMejdalani 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. bromelicolaMejdalani et al., 2014 is newly recorded from southern Brazil.
Highlights
The sharpshooter genus Cavichiana Mejdalani et al, 2014 previously comprised a single species, C. bromelicola Mejdalani et al, 2014, exclusively found in bromeliads from the states of São Paulo and Rio de Janeiro, southeastern Brazil (Mejdalani et al 2014)
The four diagnostic features of Cavichiana given in the introduction are clearly present in the new species; we are confident about the generic assignment
Cavichiana alpina sp. nov. is similar to the congeneric C. bromelicola (Figs 23-26), but the new species can be distinguished by its larger size (7.5–8.2 mm) and remarkable coloration of dorsum
Summary
The sharpshooter genus Cavichiana Mejdalani et al, 2014 previously comprised a single species, C. bromelicola Mejdalani et al, 2014, exclusively found in bromeliads from the states of São Paulo and Rio de Janeiro, southeastern Brazil (Mejdalani et al 2014). Mejdalani et al (2014) cited the presence of a crown of spines at the aedeagal apex as a diagnostic feature of Cavichiana, but this crown is lacking in the new species here described. A new bromelicolous species of Cavichiana is described and illustrated based on material from Itatiaia National Park, municipality of Itamonte, state of Minas Gerais, southeastern Brazil. Notes on the distribution of the genus are provided
