Measurements (mm; n = 3): total length 5.89–6.39; crown length 0.54–0.56; transocular width 1.30–1.40; interocular width 0.56–0.62; maximum pronotal width 1.42–1.52; forewing length 4.84–5.15. Description. Head ( Fig. 35 ) with median length of crown about 9/10 interocular width and 4/10 transocular width. Pronotum ( Fig. 35 ) width slightly greater than transocular width. Female terminalia. Sternite VII ( Fig. 36 ), in ventral view, well produced posteriorly, triangular. “Internal” sternite VIII without distinct sclerites. Pygofer ( Fig. 37 ), in lateral view, moderately produced posteriorly, macrosetae distributed on posterior 1/2 and extending anteriorly along ventral margin. Valvifer I, in lateral view, elliptical. Valvula I ( Figs 38, 39 ), in lateral view, broadened dorsally on apical portion, narrowing gradually towards acute apex; dorsal sculptured area restricted to apical 1/2 of blade, 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. 40 ), in lateral view, moderately expanded beyond basal curvature, narrowing slightly towards apex; without preapical prominence; apical portion triangular; apex narrowly rounded; dorsal margin with about 30 teeth; most teeth subtriangular or obtuse dorsally, short, with anterior and posterior portions oblique, apex ( Fig. 41 ) rounded; denticles absent; ventral margin with denticles on apical portion; blade surface with irregular granulate sculpturing, rod-shaped apically. Gonoplac ( Fig. 42 ), 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. FIGURES 35–45. Metacephalus facetus (Kramer, 1961) . Female: 35, dorsal habitus; 36, sternite VII, ventral view; 37, pygofer and anal tube, lateral view; 38, valvula I, lateral view; 39, apical portion of valvula I; 40, valvifer II and valvula II, lateral view; 41, apical portion of valvula II; 42, gonoplac, lateral view; 43, lateral habitus; 44, head and anterior thorax, anterior view; 45, ventral habitus. Scale bars: 35, 43–45 = 1 mm; 36–42 = 0.2 mm. Color. Ground color of dorsum generally brown. Crown ( Fig. 35 ) mostly orange with pair of subtriangular, adjacent dark brown to black spots located at apex. Eyes dark brown. Pronotum ( Fig. 35 ) with dark brown vermicula- tions. Mesonotum mostly orange, with pair of basilateral, dark brown to black triangular areas. Forewing ( Figs 35, 43 ) clavus with large, arrow-shaped transcommissural orange marking extending from basal portion (continuous with orange area of mesonotum) to apex; outer border of this marking lined with dark brown. Frons and clypeus ( Figs 44, 45 ) brown, their external borders with pair of dark brown stripes converging inferiorly; gena, lorum, and maxillary plate dull yellow with irregular brown markings. Thoracic sclerites ( Figs 43, 45 ) brownish-yellow to brown laterally and ventrally. Legs mostly brownish-yellow. Material examined. Brazil—Acre State: two females, Porto Acre ( MPEG ); Amazonas State : one female, Rio Preto da Eva ( DZRJ ); one female, Presidente Figueiredo ( INPA ).
