Portanus restingalis Felix & Mejdalani, 2016 

( Figs 22–34View FIGURES 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. 22View FIGURES 22–34) with median length of crown about 8/10 interocular width and 4/10 transocular width. Pronotum ( Fig. 22View FIGURES 22–34) width slightly less than transocular width.

Female terminalia. Sternite VII ( Fig. 23View FIGURES 22–34), in ventral view, moderately produced posteriorly; posterior margin with distinct subtrapezoidal median lobe. “Internal” sternite VIII without distinct sclerites. Pygofer ( Fig. 24View FIGURES 22–34), 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, 26View FIGURES 22–34), 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, 27View FIGURES 22–34), 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. 28View FIGURES 22–34), 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, 30View FIGURES 22–34) 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. 31View FIGURES 22–34), 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. 22View FIGURES 22–34) 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, 33View FIGURES 22–34) 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, 33View FIGURES 22–34) orange to brown. Forewing ( Figs 22, 33, 34View FIGURES 22–34) 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, 34View FIGURES 22–34) pale yellow; apical portion of labium dark brown. Thoracic sclerites ( Fig. 33View FIGURES 22–34) pale yellow laterally and ventrally. Legs mostly pale yellow.
