Physatocheila orientis Drake, 1942: 9.
Diagnosis. Body reddish-brown, elongated-oval, fusiform (Fig. 1D); middle part of anterior margin of hood slightly convex (Fig. 2D); paranota narrow, maximal width from anterolateral margin to inner margin less than the minimal width between paranota, inner margin reaching lateral carina (arrows; Figs. 2D, 3A); areolae size not consistent in costal area, 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 (Fig. 4D); middle part of inner margin of paramere almost straight (Fig. 5D); middle part of outer margin of pygophore sinuate (Fig. 6D).
Description. Male: Body generally brown, elongated oval, fusiform-shaped.
Head dark brown; antennae brown; first segment distinctly thicker than second segment; third segment equal to 3X fourth segment in length; fourth segment dark brown; hood brown, middle part slightly convex.
Pronotum brown; paranota brown, narrow, maximal width from anterolateral margin to inner margin less than the minimal width between paranota, inner margin almost straight, reaching lateral carina, with five rows of areolae in dorsal view; areolae consistent in size.
Hemelytra 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 almost straight; apophysis long and narrow, its apex sharp (Fig. 5D); pygophore angulated posterolaterally; middle part concave in ventral view (Fig. 6D).
Female: Head, pronotum, hemelytra: As in male. Genitalia: not examined.
