Diagnosis. This new species can be distinguished by the following combination of features: (1) apical third of ventral margin of male pygofer with inner setose process very small ( Fig. 2 ); (2) male abdominal segment X (anal tube) without processes ( Fig. 5 ); (3) style with apex narrow, obtuse, not foot-shaped ( Fig. 3 ); (4) aedeagus with distinct dorsal lobe along basal two-thirds and with apical portion expanded, bearing dorsal projection ( Fig. 5 ); (5) paraphyses with distal pair of rami forceps-like, their basal halves divergent from each other, distal halves approximately parallel, apices acute ( Fig. 4 ); (6) female sternite VII with posterior margin shallowly emarginate, bearing slight median lobe ( Fig. 7 ); and (7) valvula II of ovipositor with approximately 15 low teeth ( Figs 12–14 ).

Description. Length of male holotype 6.1 mm, male paratype 6.1 mm, female paratypes 5.9–6.5 mm (n = 3).

Male. Head ( Fig. 1 ), in dorsal view, well produced anteriorly, rounded apically; median length of crown approximately seven-tenths of interocular width and four-tenths of transocular width. Ocelli located slightly before imaginary line between anterior eye angles, each slightly closer to adjacent anterior eye angle than to median line of crown. Antennal ledge, in dorsal view, slightly protuberant; in lateral view, with anterior margin slightly oblique and convex. Frons with median portion slightly convex; epistomal suture obscure medially; clypeus not protuberant.

Thorax ( Fig. 1 ), in dorsal view, with pronotal width approximately equal to transocular width of head; pronotum with lateral margins slightly convergent anteriorly; posterior margin concave; dorsolateral carena declivous anterad, indistinct at area adjacent to eye. Mesonotum with scutellum slightly transversely striate. Forewing ( Fig. 1 ) with membrane not sharply delimited, including at least apical cells, much of anteapical cells, and costal apical cell; with three closed anteapical cells, their bases proximal to claval apex. Hind wing with vein R 2+3 incomplete. Hind leg with length of first tarsomere approximately equal to combined length of two more distal tarsomeres, with two parallel rows of small setae on plantar surface.

Color ( Fig. 1 ). Ground color of dorsum pale yellow to green mottled with many irregular brown vermiculations and spots. Anterior margin of crown and mesonotum with larger spots. Membrane of forewing translucent, with green spots on anteapical cells. Face, lateral and ventral portions of thorax, and legs mostly yellow; superior portions of antennal ledge and lateral lobe of pronotum with brown spot.

Terminalia. Pygofer ( Fig. 2 ), in lateral view, strongly produced posteriorly; distal half slightly narrower than basal half; posterior margin broadly rounded; apical third of ventral margin with small inner process bearing setae, additional processes absent; macrosetae distributed mostly on posterior portion and extending anteriorly along ventral margin. Subgenital plate ( Fig. 3 ), in ventral view, subtriangular, with basal one-fourth distinctly expanded and then narrowing gradually toward apex; surface with mostly small macrosetae along outer margin, microsetae also present; plates not fused to each other at base; in lateral view, not extending as far posteriorly as pygofer apex. Connective ( Fig. 3 ), in dorsal view, Y-shaped; stalk with slight median keel. Style ( Fig. 3 ), in dorsal view, extending posteriorly beyond apex of connective; with distinct outer preapical lobe; outer preapical area bearing setae; apex narrow, obtuse, not foot-shaped. Aedeagus ( Figs 5, 6 ) symmetrical; shaft, in lateral view, elongate; basal two-thirds with distinct dorsal lobe; apical portion expanded, with slight dorsal projection, dorsal margin straight from projection to apex; gonoduct distinct, gonopore located ventroapically. Paraphyses ( Fig. 4 ), in dorsal view, with stalk elongate, slightly constricted medially, articulated with apex of connective; with two pairs of rami: proximal pair direct- ed anterad, slightly asymmetrical; distal pair directed posterad, forceps-like, basal halves of rami divergent from each other, distal halves approximately parallel, their apices acute. Anal tube ( Fig. 5 ), in lateral view, with segment X lacking inner process.

Female. External form and color as described above for the male. Terminalia. Sternite VII ( Fig. 7 ), in ventral view, slightly narrowed posteriorly; posterior margin shallowly emarginate, bearing slight median lobe. “Internal” sternite VIII ( Fig. 8 ), in dorsal view, with irregular, median sclerotized area associated with ovipositor base. Pygofer ( Fig. 9 ), in lateral view, slightly produced posteriorly; posterior margin broadly rounded; few macrosetae on posterior portion and near posteroventral margin. Valvifer I, in lateral view, subquadrate. Valvula I ( Figs 10, 11 ), in ventral view, with basal portion triangularly expanded; blade, in lateral view, slightly curved dorsally; apex acute; ventral interlocking device elongate, extending along basal half of valvula; blade surface, especially basal half, with few small setae [trichoid sensilla] and many pores located below or adjacent to ramus, base with distinct group of denticuli; dorsal sculptured area extending from basal portion to apex of blade, formed by distinct scale-like processes arranged mostly in oblique lines; ventral sculptured area restricted to apical portion, formed by scale-like processes. Valvula II ( Figs 12–15 ), in lateral view, only slightly expanded beyond basal curvature; ventral preapical prominence inconspicuous; apex obtuse; dorsal margin with approximately 15 low, poorly defined teeth that become progressively smaller toward apex, basalmost three teeth very elongate; denticles distributed on teeth and on apical portion of blade (dorsal dentate apical portion longer than ventral portion); valvula with ducts extending to teeth (or terminating below them) and to apex; membrane associated with basal portion of valvula with distinct pores. Gonoplac ( Fig. 9 ) of the usual Cicadellinae type: in lateral view, distinctly expanded at apical half; apex obtuse; denticuli distributed at basal half, narrow area along ventral margin of apical half, and apex; these areas also bearing few setae.

Type material. Southeastern Brazil, Mantiqueira mountain range, states of Minas Gerais and São Paulo. Holotype male: “ Wenceslau Braz \ MG [Minas Gerais] 15-31/X/2019 \ J. A. FROZA ” ( MELQ, ESALQENT001731 ). Paratypes: two females, “ Wenceslau Braz \ MG 01-16/XI/2018 \ J. A. FROZA ” ( MELQ, ESALQENT001732 and 001733); one male and four females, “ Wenceslau Braz \ MG \ 30/IX-15/X/2019 \ J. A. FROZA col.” ( MNRJ); one male, “ São Bento do \ Sapucaí – SP [São Paulo] \ 14-28/IX/2019 \ J. A. FROZA col.” ( MNRJ); one male, “ São Bento do Sapucaí \ SP X-2015 \ J. A. FROZA ” (destroyed by the fire at MNRJ).

Etymology. The new species is described in honor of Maria Aparecida Froza, first author’s mother, who greatly encouraged her for the scientific career and life.
