Portanus restingalis Felix & Mejdalani, 2016

( Figs 22–34 )

Female. Measurements (mm; n = 2): total length 6.47–6.56; crown length 0.60; transocular width 1.56–1.58; interocular width 0.72–0.78; maximum pronotal width 1.46–1.54; forewing length 5.15–5.27.

Description. Head ( Fig. 22 ) with median length of crown about 8/10 interocular width and 4/10 transocular width. Pronotum ( Fig. 22 ) width slightly less than transocular width.

Female terminalia. Sternite VII ( Fig. 23 ), in ventral view, moderately produced posteriorly; posterior margin with distinct subtrapezoidal median lobe. “Internal” sternite VIII without distinct sclerites. Pygofer ( Fig. 24 ), in lateral view, moderately produced posteriorly; apex triangular; with macrosetae distributed mostly on distal 1/2 of disk, some extending anteriorly near ventral margin. Valvifer I, in lateral view, elliptical to subquadrangular. Valvula I ( Figs 25, 26 ), in lateral view, slightly broadened dorsally on apical 1/2, narrowing gradually towards acute apex; dorsal sculptured area extending along distal 2/3 of blade ( Figs 26, 27 ), very narrow basally, formed mostly by rod-shaped elements; ventral sculptured area restricted to apical portion, formed by sparse scale-like processes; ventral interlocking device located on basal 1/3 of blade; in ventral view, basal portion of valvula I with slight outer lobe. Valvula II ( Fig. 28 ), in lateral view, slightly expanded beyond basal curvature, distinctly narrowed towards apex; without preapical prominence; apical portion triangular; apex narrowly rounded; dorsal margin with about 30 teeth; most teeth ( Figs 29, 30 ) subtriangular or obtuse dorsally, short, with anterior and posterior portions oblique; ventroapical margin serrate; blade surface with irregular granulate sculpturing, rod-shaped apically. Gonoplac ( Fig. 31 ), in lateral view, abruptly 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. Dorsum ( Fig. 22 ) brownish-yellow with ivory areas; narrow, irregular orange median stripe extending from anterior portion of crown to scutoscutellar suture of mesonotum, sometimes interrupted. Crown ( Figs 22, 32, 33 ) with apical transverse ivory band on ocelli region; two conspicuous transverse dark brown stripes, one below and one above ocelli; pair of transverse ivory marks located medially behind superior dark brown stripe. Eyes ( Figs 22, 32, 33 ) orange to brown. Forewing ( Figs 22, 33, 34 ) translucent; veins mostly yellowish-brown; clavus with irregular pale markings; corium with brown macula near costal margin, approximately opposite apex of clavus; basal veins of apical cells marked with brown; apical portion of apical cells slightly darkened. Face ( Figs 32, 34 ) pale yellow; apical portion of labium dark brown. Thoracic sclerites ( Fig. 33 ) pale yellow laterally and ventrally. Legs mostly pale yellow.

Material examined. Brazil—Rio de Janeiro State: two females, Rio de Janeiro ( MNRJ); one female, Rio de Janeiro ( DZRJ).
