Recognised by the head height 2.2 times the width; vertex as wide as four times minimal distance between eyes (in frontal view); frons pale with longitudinal dark stripes; antennal segment II mostly pale, the apical part dark, and as long as 1.23 times segment III. FIGURE 3. Male genitalia of Megalofaciatus foliotibialis : left paramere (A) , right paramere (B) , aedeagus in dorsal view (C) . Description. Male. Dorsum partly dark and pale brown, glossy, covered by erect, long and shiny, silvery setae ( Figs 1A, B ). Head : pale with reddish compound eyes, dark ocelli, and dark longitudinal stripes, height 2.2 times width; vertex pale brown, tinged with reddish, slightly concave between ocelli, four times as wide as minimal distance between eyes (in frontal view) ( Fig. 1C ); frons pale with a total of four longitudinal dark stripes; gena pale brown ( Figs 1B, C ); antennae mostly brown and cylindrical; segment I dirty yellow, segment II brown, with apical part dark brown, segments III and IV yellowish brown; the proportion of antennal segments 0.18: 1.55: 1.26: 0.45; labium mostly brown and shiny, reaching abdominal segment II; segment I reddish-brown; apical part of segment III yellowish-brown; apical part of segment IV brown except yellow-brown apex ( Fig. 1B ); the proportion of labial segments 0.70: 0.71: 0.55: 0.66.

Hemelytron : mostly hyaline with dark punctures and brownish veins; corium covered with brown setae originating from within punctures; claval and R+M veins with densely dark punctures; embolial margin clear, with short, sparse setae, inner and outer margin with tiny dark punctures posteriorly; cuneus semitransparent, dirty yellow; membrane transparent with two dark cells. Legs: coxae brown; forefemur pale with a brownish base, an annulation on distal third, and a reddish apex; foretibia brown, with apical part pale; foretarsus brown; midfemur pale brown with brown annulation subapically, tinged with reddish at apex; midtibia brown, tinged with reddish basally, paler apically; midtarsus brown; hindleg mostly dark brown, hindfemur mostly reddish dark brown except pale basal part; hindtibia reddish dark brown except for the pale apical part, broadly developed, leaf-shaped, narrowing apically; hindtarsus brown ( Fig. 1A ). Abdomen : brown, covered with golden setae ( Fig. 1B ). Genitalia: left paramere scythe-shaped, with a long, vertically curved hypophysis and a broad sensory lobe, hypophysis tapered to the apex and as thick as neck diameter, sensory lobe with long, sparse setae; right paramere scythe-shaped, hypophysis thin and rounded apically, sensory lobe as broad as two times neck diameter ( Figs. 3A, B ); endosoma membranous, membrane part with small spinules ( Fig. 3C ).
