(Figs. 7–14)
Amasha inepta Medler, 1992: 25. Holotype, female, Bian, Mt Lang, Vietnam, 1500–2000 m, 19.v.–8.vi.1961, N.R. Spencer (BPBM).
Color. Body and tegmen grayish-green, aged specimens ochreous or stramineous; postclaval sutural margin, apical margin and apical half of costal margin normally red, without black dots. Eye dark brown.
Structure. Body length 12.10–13.02. Head including eyes narrower than pronotum; vertex wider (1.16– 1.31) than long (0.33–0.49), anterior margin of vertex widely obtuse, angled at 140°, separated with frons by U-shaped carina, lateral margin slightly raised; transverse intergenal carina distinct, touched anterior margin of pronotum (Figs. 7–8). Frontal disc flat, not convex, wider (1.49–1.54) at widest part than long (1.41–1.50) in middle line, lateral margin slightly elevated, with very short median and U-shaped carina at dorsal side (Fig. 9); frontoclypeal suture shallowly convex, clypeus triangular, strongly convex (Fig. 9); rostrum extended to meso-trochantes. Pronotum longest in midline (0.58–0.63). Mesonotum with three longitudinal carinae. Post-tibia with six or seven spines apically, basal tarsal segment with eight or nine spines apically. Tegmen length 10.13–11.06, width between costal margin and apex of clavus 5.61–5.96, costal membrane as wide as costal cell; postclaval sutural margin extended from apex of clavus at angle of 175°, meeting apical margin at angle of 97°, with 10–13 apical cells; branch of vein M not merged with Cu1; one distinct subapical line (Fig. 10).
Male genitalia. Pygofer ring-like, in lateral view with anterior margin sinuate concave, posterior margin shallowly convex (Fig. 11). Genital style triangle, with strong process at dorsocaudal portion. Anal segment long, apical half right angled in lateral view (Fig. 11), in dorsal view lateral margin with apical third convex, apical margin emarginate deeply (Fig. 14). Phallus slightly arched (Fig. 12); phallobase tubular, with line of tiny teeth from middle of dorsal margin to middle of lateral portion, dorsolateral emargination shallow in lateral view, with two processes, outer one sinuate, short and strong, inner one cephaloventrad reaching middle of phallobase and bifurcated in different lengths (Figs. 12–13); ventral lobe pointed at apex, in ventral view long triangular (Fig. 13); ventrolateral portion with lateral lobe at middle, dorsal margin straight, ventral margin arched, basal half with small saw teeth; theca bipartite, in lateral view apex of theca broad and rounded, near apex with pair of short ear-like processes (Fig. 12).
Material examined: 23, 1Ƥ: Botanical garden, Ruili, Yunnan Province, China, 1200m, 2.vii.2007, Wei Cong (NWAFU); 2ƤƤ: Maguanpo, Yunnan Province, China, 9.vi.1979, Zhang Guipei (NWAFU); 1Ƥ: Lianggou, Yunnan Province, China, 4.v.1979 (NWAFU).
Distribution: China (Yunnan), Vietnam (Lam Dong).
Remarks: This species was described by Medler (1992) based on one female specimen, and its tegmen was tattered. He did not give any figures of the external characters. This species can be distinguished from other species of the genus by: Cu1 not merged, freely to sutural margin; male phallobase with a bifurcated process only reaching middle of phallobase.
