Fonsecaiulus takiyae sp. nov.

( Figs 79–96 )

Etymology. This species is named in honor of our colleague and friend Prof. Dr. Daniela M. Takiya (Universidade Federal do Rio de Janeiro), who has greatly contributed to our knowledge of the Cicadellidae and other insects.

Total length (mm). Male holotype 5.50; male paratypes 5.20–5.60 (n = 3); female paratypes 5.55–5.90 (n = 3).

Color ( Figs 79–81 ). Dorsum dark brown with three longitudinal yellow stripes; median stripe broad, extending from anterior margin of crown to apex of clavus, narrowed posteriorly on basal half of clavus; lateral stripes narrow, extending from anterior margin of crown to posterior margin of mesonotum; veins of clavus and claval sulcus covered with yellow. Corium with two irregular yellow stripes extending from anterior portion of brachial cell and connecting posteriorly to each other on inner anteapical cell, outer stripe narrower than inner one; very narrow yellow stripe extending longitudinally near costal margin, posteriorly connected to yellow macula on median and outer anteapical cells.

Male terminalia. Pygofer ( Fig. 82 ), in lateral view, well produced posteriorly; posterior margin narrowly rounded; without processes; sparse macrosetae of distinct sizes on posterior portion and extending anteriorly over ventral portion. Valve ( Fig. 83 ), in ventral view, short and broad, subrectangular; anterior margin slightly concave. Subgenital plate ( Figs 82–83 ), in ventral view, subtriangular, basal half broad and with outer margin rounded; plate fused at base to its counterpart; without macrosetae; in dorsal view, with two tiny dentiform processes at apical portion of basal half, 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. 84 ), in dorsal view, forming transverse bar, with small stalk, slightly curved posteriorly, with dorsal median keel. Style ( Fig. 84 ), in dorsal view, short but extending farther posteriorly than connective; apophysis with inconspicuous preapical lobe; portion behind lobe strongly narrowed, falciform, bearing setae; apex tapered. Aedeagus ( Figs 85, 86 ), in lateral view, elongate, tubular, tapering slightly toward apex; with pair of slender, acute basiventral processes and pair of small, acute ventroapical processes; gonopore located apically. Paraphyses absent.

Female terminalia. Sternite VII ( Figs 87–89 ), in ventral view, with posterior margin trilobed; median lobe broad, rounded. “Internal” sternite VIII, in dorsal view, with sclerotized areas, including three distinct sclerites (indicated by arrows in Fig. 91 ). First valvifer ( Fig. 90 ), in lateral view, subquadrate. First valvula ( Figs 90, 92 ), second valvula ( Figs 93–95 ), and gonoplac ( Fig. 96 ) much as described for F. spinosus sp. nov. Second valvula with about 32 teeth.

Remarks. Fonsecaiulus takiyae sp. nov. is our second new species that has no paraphyses. In addition to this feature, it can be distinguished from the remaining species of the genus by the elongate aedeagus, which has a pair of slender, acute basiventral processes and a pair of small, acute ventroapical processes ( Figs 85, 86 ). The posterior margin of the female sternite VII in F. takiyae is trilobed as in F. unciformis sp. nov., but the median lobe is rounded in the former species ( Fig. 89 ) and subquadrate in the latter one ( Fig. 53 ). The “internal” sternite VIII, in dorsal view, has three distinct sclerites ( Fig. 91 ).
