sp. nov.

Amblyscarta souzalopesi  sp. nov.

( Figs 18–34View FIGURES 18–26View FIGURES 27–34)

Total length (mm). Male 8.7–8.8 (holotype 8.7); female 9.1.

Color ( Figs 18–20View FIGURES 18–26). Very similar to A. elianeae  sp. nov., but with usually thinner brown stripes, vermiculations, and spots.

Male terminalia. Pygofer ( Fig. 21View FIGURES 18–26), in lateral view, moderately produced posteriorly; posterior margin slightly triangular; without processes; macrosetae distributed mostly on posterior third. Valve ( Fig. 22View FIGURES 18–26), in ventral view, large; posterior margin broadly rounded. Subgenital plate ( Figs 21, 22View FIGURES 18–26), in ventral view, triangular, narrowing gradually towards apex; fused basally to its counterpart; with uniseriate macrosetae along outer margin; in lateral view, extending almost as far posteriorly as pygofer apex. Style ( Fig. 23View FIGURES 18–26), in dorsal view, extending much farther posteriorly than connective; without preapical lobe; apical portion slightly curved outwards, inner margin not dilated and without tiny apical tooth; apex truncate. Aedeagus ( Figs 24–26View FIGURES 18–26) symmetrical; shaft, in lateral view, with ventral margin rectilinear for most of its length and dorsal margin almost entirely convex; apex with pair of triangular acute processes slightly directed anterad; gonopore located ventroapically.

Female terminalia. Sternite VII ( Figs 27, 28View FIGURES 27–34), in ventral view, with strong triangular projection on posterior margin. “Internal” sternite VIII without distinct sclerites. Pygofer ( Figs 27, 28View FIGURES 27–34), in lateral view, moderately produced posteriorly; posterior margin narrowly rounded; macrosetae distributed on posterior portion and extending anteriorly along ventral margin. Valvifer I ( Fig. 29View FIGURES 27–34), in lateral view, subquadrangular. Valvula I ( Figs 29, 30View FIGURES 27–34), in lateral view, with acute apex; dorsal sculptured area extending from basal portion to apex of blade, strigate; ventral sculptured area restricted to apical portion, strigate; ventral interlocking device distinct along basiventral half of blade; in ventral view, basal portion of valvula I expanded outwards. Valvula II ( Figs 31–33View FIGURES 27–34), in lateral view, expanded beyond basal curvature; dorsal margin convex, bearing about 20 teeth; basal portion of most teeth projected dorsally, their posterior portion flat, apical teeth triangular; denticles distributed on teeth and on dorsal and ventral apical portions of blade (ventral denticulate apical portion longer than dorsal portion); preapical prominence distinct; apex obtuse; valvula with ducts extending towards teeth and apex. Gonoplac ( Fig. 34View FIGURES 27–34) of the usual Cicadellinae type: in lateral view, with basal half narrow; apical half expanded, gradually narrowing towards apex; latter obtuse; tiny denticuli on apical portion and extending anteriorly along ventral margin.

Material examined. Male holotype: “ RIO DE JANEIRO \ JARD  . [Jardim] BOTÂNICO \ H.S. LOPES 2-935  [February, 1935]” ( MNRJ). Paratypes: 1♀, “ RIO DE JANEIRO \ GAVEA  [Gávea] 11-V- 937 [1937] \ H. SOUZA LOPES ” ( MNRJ); 1♂, “ Rio de Janeiro \ RJ [Rio de Janeiro] VII/1972 \ M. Alvarenga ” ( DZUP)  .

Etymology. The new species is named in honor of the eminent late Brazilian naturalist Hugo de Souza Lopes, who collected the holotype and one of the paratypes.
