Abstract
Three new sharpshooter species of the genus Fonsecaiulus Young, 1977 are described and illustrated from specimens collected in the Brazilian Atlantic Forest, Fonsecaiulus rectangularis and Fonsecaiulus guttiformis, and in the Brazilian Cerrado, Fonsecaiulus filiformis. The descriptions are based on features from the external morphology, color pattern, and male and female genital structures. Comparisons of the three new taxa with the remaining six Fonsecaiulus species are provided. An identification key to males of all known species of the genus is given.
Highlights
The genus Fonsecaiulus Young, 1977 occurs in Venezuela, NE, CW, SE and S Brazil, Bolivia, and Argentina, being composed of six species (Young 1977): F. cognatus (Schmidt, 1928); F. dorsifascia (Osborn, 1926); F. flavovittata (Stål, 1859), the type species; F. gaudialis Young, 1977; F. sanguineovittata (Signoret, 1855); and F. sciotus Young, 1977
Specimens of Fonsecaiulus have a conspicuous median yellow stripe covering at least the anterior dorsum, limited by a pair of black to brown stripes or areas
In this paper three new species of Fonsecaiulus are described and illustrated from specimens collected in Atlantic Forest areas from Espírito Santo State, SE
Summary
The genus Fonsecaiulus Young, 1977 occurs in Venezuela, NE, CW, SE and S Brazil, Bolivia, and Argentina, being composed of six species (Young 1977): F. cognatus (Schmidt, 1928); F. dorsifascia (Osborn, 1926); F. flavovittata (Stål, 1859), the type species; F. gaudialis Young, 1977; F. sanguineovittata (Signoret, 1855); and F. sciotus Young, 1977. The direction of the pygofer processes is variable; the aedeagal shaft can be more dorsally curved than in the holotype; its apical portion, in lateral view, can be broader and the apical margin, slightly concave.
