Metacephalus facetus
(Kramer, 1961)
(
Figs 35–45
)
Female. 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.

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.
