(Figs. 1C, 2C, 4C, 5C, 6C)

Monanthia fieberi Scott, 1874: 291, 442.

Physatocheila monstrosa (not Scott, 1874): Takeya, 1951: 20. Misidentification (see Drake & Maa, 1954: 112).

Diagnosis. Body brown with dark parts, elongated (Fig. 1C); paranota largely developed, maximal width from anterolateral margin to inner margin much wider than the minimal width between paranota, inner margin covering lateral carinae, almost reaching medial carina (Fig. 2C); costal area with two rows of areolae, areolae size similar, areolae in outer part larger, except for those of middle part; areolae size of discoidal area distinctly larger than those of subcostal area (Fig. 4C); middle part of inner margin of paramere almost straight (Fig. 5C); middle part of outer margin of pygophore slightly sinuate (Fig. 6C).

Description. Male: Body fuscous to dark brown, elongated.

Head brown, with five spines; antennae brown; first segment as equal as second segment in length, stout; third segment more than 3X fourth segment in length; fourth segment of antennal dark brown; hood brown, middle part slightly produced.

Pronotum brown; paranota brown, largely developed, maximal width from anterolateral margin to inner margin much more than the minimal width between paranota, inner margin almost reaching medial carina, with five to six rows of areolae in dorsal view; areolae of paranota similar in size.

Hemelytra brown, slightly wider than maximum width of pronotum, outer margin sinuate; costal area with two rows of areolae, areolae size consistent from basal to middle part, areolae of posterior part larger; subcoastal area with small areolae, areolae distinctly smaller than those of costal and discoidal areas.

Genitalia: paramere scythe-shaped, inner margin vertically angled; sensory lobe thick, inner margin almost straight; apophysis rounded, distinctly shorter than inner margin of sensory lobe (Fig. 5C); pygophore smoothly angulated posterolaterally; middle part of outer margin slightly sinuate (Fig. 6C).

Female: Head, pronotum, hemelytra: As in male. Genitalia: not examined
