Abstract

A new species of Scoposcartula Young, 1977 is described and illustrated based on material from the Atlantic Forest of Rio de Janeiro State, Southeastern Brazil. Scoposcartula tentaculata sp. nov. can be easily distinguished from the other 15 known species of the genus by the colour of the forewings (black to dark brown with a very large red area on the basal half) and by the conspicuous paraphysis, which is very long and tentacle-like. The new species was added to a recently published morphological data matrix of Scoposcartula species. Cladistic analysis of these data suggested that S. tentaculata sp. nov. is the sister group of S. lancifera Young, 1977. These sister species belong to a group that also includes S. tobiasi Cavichioli & Mejdalani, 1996 + S. limitata (Signoret, 1953). Hypotheses of vicariance for explaining the present distributions of these four species are suggested. The use of Cicadellinae taxa as models for studies of vicariance in the Neotropics is briefly addressed.
