Fonsecaiulus youngi View in CoL sp. nov.

( Figs 1–8 View FIGURES 1–8 )

Etymology. This species is named in honor of the late Prof. Dr. David A. Young (1915–1991), who published three impressive monographs on the Cicadellinae (1968, 1977, 1986). Fonsecaiulus was described in the 1977 monograph.

Total length (mm). Male holotype 6.13.

Color ( Figs 1–3 View FIGURES 1–8 ). Dorsum brown with three longitudinal yellow stripes extending from anterior margin of crown to apex of clavus; median stripe narrowed posteriorly from median portion of pronotum, continuing as narrow line along commissural margins; lateral stripes strongly narrowed on median portion of clavus. Corium with irregular yellow stripe extending from anterior portion of brachial cell to inner anteapical cell, strongly narrowed along anterior third; very narrow yellow stripe extending longitudinally near costal margin, posteriorly connected to yellow macula on median and outer anteapical cells.

Male terminalia. Pygofer ( Fig. 4 View FIGURES 1–8 ), in lateral view, well produced posteriorly; posterior margin subtriangular; without processes; macrosetae of distinct sizes on posterior portion and extending anteriorly over ventral portion. Valve ( Fig. 5 View FIGURES 1–8 ), in ventral view, short and broad, subrectangular; anterior margin slightly concave. Subgenital plate ( Figs 4, 5 View FIGURES 1–8 ), in ventral view, broad at basal two-thirds and narrow at apical third, these areas not separated by constriction; plate fused at base to its counterpart; without macrosetae; in dorsal view, with two tiny dentiform processes at apical portion of basal two-thirds, not located close to each other, anterior process associated with style apex; in lateral view, plate not extending as far posteriorly as pygofer apex. Connective ( Fig. 6 View FIGURES 1–8 ), in dorsal view, short, Y-shaped; stalk with median keel. Style ( Fig. 6 View FIGURES 1–8 ), in dorsal view, extending farther posteriorly than connective; apophysis with preapical, slight angulate lobe; portion behind lobe narrowed, bearing setae; apex slightly expanded, truncate. Aedeagus ( Figs 7, 8 View FIGURES 1–8 ) symmetrical; shaft, in lateral view, curved dorsally and tall; dorsal margin with elongate preapical spine directed posteriorly; apex acute; in ventral view, shaft flattened for most of its length, slightly expanded apically, apical portion with fusiform crown of spines; gonopore located ventroapically. Paraphyses ( Figs 7, 8 View FIGURES 1–8 ), in lateral view, with pair of sinuous acute rami, extending as far posteriorly as aedeagal apex.

Female unknown.

Type material. Holotype: male, “ Brasil, Minas Gerais, \ PN [Parque Nacional] da Serra do Cipó 9– \ 13.XII.2011 (Malaise) \ Santana do Riacho , \ Córrego das Pedras”; “ 19°22′17″S \ 43°36′03″W 766m \ Monné, M.L.; Santos, \ A.; Takiya, D.M. & \ Cavichioli, R.R.” ( DZUP). GoogleMaps

Remarks. Fonsecaiulus youngi sp. nov. can be distinguished from the remaining species of the genus by the aedeagus, in lateral view, with an elongate preapical spine directed posteriorly ( Fig. 7 View FIGURES 1–8 ) and, in ventral view, with a fusiform crown of spines ( Fig. 8 View FIGURES 1–8 ). The paraphyses in this new species have a pair of sinuous acute rami that extend as far posteriorly as the aedeagal apex ( Figs 7, 8 View FIGURES 1–8 ) and the subgenital plates are narrowed at the apical third ( Fig. 5 View FIGURES 1–8 ).
