( Figs 46–52View FIGURES 46–52)

Female. Measurements and external description as in Souza, Takiya & Felix (2017).

Female terminalia. Sternite VII ( Fig. 46View FIGURES 46–52), in ventral view, subrectangular; posterior margin broadly convex medially; posterolateral angles rounded. “Internal” sternite VIII without sclerites. Pygofer ( Fig. 47View FIGURES 46–52), in lateral view, moderately produced posteriorly, row of sparse macrosetae along ventroapical margin and few grouped on apical portion. Valvifer I, in lateral view, with dorsal and ventral margins convex; distal margin truncate. Valvula I ( Figs 48, 49View FIGURES 46–52), in lateral view, slightly broadened dorsally on apical portion, narrowing gradually towards acute apex; dorsal sculptured area extending from basal portion of blade to apex, formed mostly by rod-shaped elements; ventral sculptured area restricted to apical portion, formed by sparse scale-like processes. Valvula II ( Figs 50, 51View FIGURES 46–52), in lateral view, moderately expanded beyond basal curvature, distinctly narrowed towards apex; without preapical prominence; apical portion triangular; apex narrowly rounded; dorsal margin with about 34 teeth; most teeth subtriangular or obtuse dorsally, short, with anterior and posterior portions oblique; denticles absent; ventral margin with long, subtriangular, not prominent teeth on apical portion, without denticles; blade surface with irregular granulate sculpturing, rod-shaped apically. Gonoplac ( Fig. 52View FIGURES 46–52), in lateral view, gradually expanded at median portion and then gradually narrowed posteriorly; apex obtuse; surface with numerous tiny denticuli apically and extending anteriorly along ventral margin, with few setae (about two or three) located apically.

Color. Ground color of dorsum generally brown. Crown mostly yellowish-orange to orange, with pair of elongate dark brown markings extending from posterior margin to near ocelli, connected to each other posteriorly, each one enclosing pale spot and connected to several dark brown vermiculations. Eyes dark brown. Pronotum with dark brown vermiculations; with orange spot behind each eye. Mesonotum with pair of orange spots laterally, adjacent to scutoscutellar suture; apex orange. Forewing mostly translucent with distinct brown veins; base of clavus with orange spot; claval commissural margin orange, bordered at basal 1/3 by broad dark brown stripe; both claval veins with elongate brown markings along their posterior portions. Ground color of face pale yellow; superior 1/2 of frons with brown vermiculations delimiting small yellow spots; inferior 1/2 with pair of irregular brown lines delimiting elongate, central elliptical yellow area; these brown lines connected inferiorly with brown lateral portions of frons; clypeus almost entirely brown; posterior margins of gena and maxillary plate brown; antennal ledge and genal area adjacent to base of antenna brown, area behind eye yellow. Thoracic sclerites mostly yellow laterally and ventrally. Legs mostly brownish-yellow.
