Diagnosis. Body reddish or dark-brown, elongated oval, fusiform ( Fig. 1E View FIGURE 1 ); middle part of hood strongly convex ( Fig. 2E View FIGURE 2 ); paranota narrow, maximal width from anterolateral margin to inner margin less than the minimal width between paranota, inner margin not reaching lateral carina (arrows; Figs. 2E View FIGURE 2 , 3B View FIGURE 3 ); areolae size not consistent in costal area, with three rows of areolae in basal part, four to five rows in middle part, two rows in apical part; areolae size of discoidal area subequal to those of subcostal area ( Fig. 4E View FIGURE 4 ); middle part of inner margin of paramere straight ( Fig. 5E View FIGURE 5 ); middle part of outer margin of pygophore slightly sinuate ( Fig. 6E View FIGURE 6 ).

Description. Male: Body reddish-brown or dark brown, elongated oval, fusiform-shaped.

Head dark brown; antennae brown; first segment distinctly thicker than second segment; third segment more than 3X fourth segment in length; fourth segment dark brown; hood brown, middle part distinctly projected.

Pronotum reddish-brown to brown, apical part dark brown; paranota reddish-brown, narrow, maximal width from anterolateral margin to inner margin less than the minimal width between paranota, inner margin almost straight, not reaching lateral carina, with three rows of areolae in dorsal view; areolae not consistent in size.

Hemelytra reddish-brown; distinctly much wider than maximum width of pronotum, outer margin rounded; costal area with various sizes of areolae, with three rows of areolae in basal part, four to five rows in middle part, and two rows in apical part; areolae size of discoidal area subequal to those of subcostal area.

Genitalia: paramere scythe-shaped; sensory lobe stout, inner margin straight; apophysis long and sharp ( Fig. 5E View FIGURE 5 ); pygophore angulated; middle part slightly concave in ventral view ( Fig. 6E View FIGURE 6 ).
