Abstract

QUINTAS, Victor; TAKIYA, Daniela M.; CORTE, Isabele  and  MEJDALANI, Gabriel. A remarkable new species of Cavichiana (Hemiptera: Cicadellidae: Cicadellinae) from southeastern Brazil. Zoologia (Curitiba) [online]. 2020, vol.37, e38783.  Epub Feb 07, 2020. ISSN 1984-4689.  http://dx.doi.org/10.3897/zoologia.37.e38783.

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.
