Holotype ♂, 1300-1400m, Huanglianshan, Luchun, Yunnan Province, China, 6.IX.2016, George Ho Wai-Chun (HKES); Paratypes 2♂ and 2♀ (including 1 subadult), 1300-1400m, Huanglianshan, Luchun, Yunnan Province, China, 6.IX.2016, George Ho Wai-Chun (HKES).

Diagnosis.-

Parasinophasma luchunense sp. n. and subsp. n. is distinctive from all other species in having a deep posterior emargination on anal abdominal segment in both sexes, spine-like appendage near the base of cerci in male and dorsoventrally flattened praeopercular organ on seventh abdominal sternum and short alae in female.

Description.-

Male (Figs 19-21, 60-62, 66): Medium-sized. Body slender and slim. Head smooth, lacking granulation. Oblong, longer than wide, distinctly longer than and broader than pronotum. Vertex flat, lacking ocelli. Occiput gently convex, median and lateral longitudinal furrows distinct. Compound eyes rounded, length about two-and-one-half times that of genae. Antennae filiform and long, densely covered with short bristles, reaching seventh abdominal tergum; scapus flattened at base, longer than pedicellus, as long as third segment. Pronotum lacking granulation, shorter than head, anterior margin weakly curved inwards, posterior margin truncate, transverse and longitudinal sulci crossing before middle area. Mesonotum slender and elongate, longer than combined length of head, pronotum, metanotum and median segment, parallel-sided, median longitudinal line indistinct, sparsely covered with small granules. Mesopleurae, mesosternum, metapleurae and metasternum lacking granulation. Abdomen parallel-sided. Ninth tergum swollen and elongate, longer than eighth tergum. Anal segment shorter than ninth tergum, with a deep V-shaped emargination on posterior margin. Poculum cup-shaped, posterior margin broad and truncate. Cerci with a small spine-like appendage near base; cylindrical, tapering posteriorly, apices pointed and curved upwards, not surpassing posterior margin of anal segment. Vomer minute, almost symmetric, gently constricted apically, apex weakly emarginated forming two indistinct lateral elevations in anteroventral view. Legs sparsely covered with short bristles. Unarmed. Profemora curved at base, longer than combined length of head, pronotum and mesonotum. Protibiae longer than mesotibiae and as long as metatibiae. Tegmina oval, as long as pronotum, posterior margin rounded. Alae short, shorter than profemora, posterior apices reaching middle area of fourth abdominal tergum.

Coloration: Dull coloration, body generally greenish brown. Head greenish brown. Genae with two faint black postocular stripes. Antennae dark brown. Pronotum brown, with three short blackish brown stripes behind transverse sulcus. Mesonotum greenish brown, with a narrow black longitudinal stripe along lateral margins. Mesosternum, mesopleurae, metapleurae and metasternum brown. Abdomen brown with black maculations. Forelegs brown, midlegs and hindlegs green. Tegmina and alae brown with blackish maculations. Anal region of alae gray.

Female (Figs 22-23, 63-65, 67): Medium-sized. Body slender, distinctly more robust than male. Head oblong, longer than wide, lacking granulation. Vertex flat. Occiput gently convex, with indistinct median and lateral longitudinal furrows. Compound eyes rounded, length about four times that of genae. Antennae filiform, sparsely covered with short bristles; scapus flattened basally, longer than pedicellus; pedicellus as long as third segment. Pronotum lacking granulation, rectangular, longer than wide, shorter than head; anterior margin incurved, posterior margin rounded, transverse and longitudinal sulci crossing before middle point. Mesonotum covered with a few small black granules; longer than combined length of pronotum, metanotum and median segment, parallel-sided, median longitudinal line indistinct. Mesopleurae, mesosternum, metapleurae and metasternum lacking granulation. Abdomen cylindrical, lacking granulation. Seventh sternum with dorsoventrally flattened praeopercular organ posteromedially, posterior margin obtuse. Eighth tergum longer than ninth tergum. Anal segment as long as ninth tergum, with a deep U-shaped emargination on posterior margin. Supra-anal plate small, posterior margin rounded, not surpassing posterolateral angles of anal segment. Subgenital plate scoop-shaped, apex pointed and not reaching middle area of anal segment. Gonapophyses not exposed. Cerci short, flattened, just surpassing posterolateral angles of anal segment. Legs sparsely covered with short bristles. Unarmed. Profemora distinctly curved basally. Mesofemora longer than mesotibiae, shorter than mesonotum. Tegmina oval, posterior margin rounded, as long as pronotum. Alae short, posterior apices only reaching posterior area of third abdominal tergum.

Coloration: General color of body greenish brown. Forelegs brown with black maculations, midlegs and hindlegs green. Tegmina and alae brown with blackish maculations. Anal region of alae light brown with gray spots.
