status

sp. nov.

Amblyscarta pinna  sp. nov.

( Figs 35–50View FIGURES 35–42View FIGURES 43–50)

Total length (mm). Male 9.0–9.3 (holotype 9.0); female 9.7–9.8.

Color ( Figs 35–37View FIGURES 35–42). Ground color of anterior dorsum orange; crown with two dark brown to black median spots, one at transition to frons and another, larger, at posterior margin; posterior portion of pronotum green with dark brown to black spots and vermiculations; mesonotum with dark brown to black markings on scutoscutellar suture and scutellum. Forewing green with dark brown to black vermiculations from base to distal portion of anteapical cells, where a transverse dark brown to black stripe is located; area behind this stripe smoky subhyaline. Face mostly orange. Legs yellow to brown.

Male terminalia. Pygofer ( Fig. 38View FIGURES 35–42), in lateral view, slightly produced posteriorly; posterior margin slightly rounded inferiorly and with emargination on superior portion; without processes; macrosetae distributed mostly on posterior third. Valve ( Fig. 39View FIGURES 35–42), in ventral view, large; posterior margin broadly rounded. Subgenital plate ( Figs 38, 39View FIGURES 35–42), in ventral view, triangular, narrowing gradually towards apex; fused basally to its counterpart; with uniseriate macrosetae along outer margin, microsetae also present; in lateral view, short, not extending as far posteriorly as pygofer apex. Style ( Fig. 40View FIGURES 35–42), in dorsal view, extending much farther posteriorly than connective; without preapical lobe; apical portion slightly curved outwards, inner margin not dilated, with tiny apical tooth; apex distinctly truncate. Aedeagus ( Figs 41, 42View FIGURES 35–42) symmetrical; shaft, in lateral view, with conspicuous, slightly asymmetrical dorsal finlike process; with pair of longitudinal lateral flanges forming apically dentiform process directed outwards; ventral margin with pair of flanges, each one with basal projection; gonopore located apically.

Female terminalia. Sternite VII ( Figs 43, 44View FIGURES 43–50), in ventral view, with strong triangular projection on posterior margin. “Internal” sternite VIII without distinct sclerites. Pygofer ( Figs 43, 44View FIGURES 43–50), in lateral view, moderately produced posteriorly; posterior margin rounded; macrosetae distributed on posterior portion and extending anteriorly along ventral margin. Valvifer I ( Fig. 45View FIGURES 43–50), in lateral view, subquadrangular. Valvula I ( Figs 45, 46View FIGURES 43–50), 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 47–49View FIGURES 43–50), 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. 50View FIGURES 43–50) 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: “ Brasil, MT  [Mato Grosso], Cláudia, Fazen-\ da Continental , 11.5841°S \ 55.3003°W, 365m, light trap, \ 17-19.vi.2017, RR Cavichioli \ & ACGoogleMaps  Domahovski ” ( DZUP). Paratypes: 1♂, 2♀, “ Brasil, MT  , Novo Mundo, \ Pq. [Parque] Est. [Estadual] do Cristalino \ 09.4517°S 55.8396°W, \ 240m, sweep, 21- 25.vi. \ 2017, ACGoogleMaps  Domahovski ” ( MNRJ, 1♀ DZUP)  .

Etymology. The new species name comes from the Latin and refers to the dorsal fin-like process of the aedeagus ( Fig. 41View FIGURES 35–42). It is a noun in apposition.

Remarks. This new species can be promptly recognized by the peculiar fin-like process of the aedeagus ( Fig. 41View FIGURES 35–42), which is unique within the genus. As in the case of the two previous new taxa, the color pattern ( Figs 35, 36View FIGURES 35–42) will readily distinguish A. pinna  sp. nov. from those poorly known species that were not included in Young’s (1977) key ( A. cervicula  , A. lignea  , A. modesta  , and A. schaumi  ; see digital images in Wilson et al. 1999).
