(Figs. 124–127, 156–163)

Types. Holotype: ♀, 1300–1400m, Fenshuiling , Jinping, Yunnan, China, 4.IX.2016, George Ho Wai-Chun ( HKES) ; Paratypes: 3♂, 1300–1400m, Fenshuiling , Jinping, Yunnan, China, 4.IX.2016, George Ho Wai-Chun ( HKES) .

Diagnosis. Oxyartes jinpingensis sp. nov. [ China (Yunnan)] is related to O. rubris sp. nov. [ China (Yunnan)], but can be separated by larger size in both sexes, spinose mesonotum in male and lacking hump-like crest on posteromedial area of fifth abdominal tergum in female.

Description. Female (Figs. 124–125, 156–158, 162). Medium-sized. General colour of body and legs brown. Body slender.

Head: Oval, as long as pronotum, with inconspicuous small granules. Vertex flat, unarmed. Occiput flat, with six small swellings on posterior margin, median and lateral longitudinal furrows indistinct. Compound eyes small and oval. Antennae long and filiform, surpassing apices of forelegs, sparsely covered with short bristles; scapus longer than pedicellus, shorter than third segment.

Thorax: Pronotum sparsely and inconspicuously covered with small granules, anterior margin weakly incurved, posterior margin rounded, transverse and longitudinal sulci crossing at middle area. Mesonotum constricted anteriorly and posteriorly, median longitudinal carina indistinct; wrinkled and inconspicuously covered with small and sparse granules. Metanotum roughly as long as median segment, with inconspicuous small granules. Mesosternum, mesopleurae, metapleurae and metasternum wrinkled and inconspicuously granulated.

Abdomen: Cylindrical. Mediolongitudinally and laterolongitudinally carinate, sparsely covered with small and inconspicuous granules. Seventh sternum lacking noticeable praeopercular organ. Eighth tergum longer than ninth tergum. Anal segment as long as ninth tergum, with two small emarginations on posterior margin. Subgenital plate scoop-shaped, reaching posterior margin of anal segment, posterior margin rounded. Cerci short, straight, flattened, apices rounded and surpassing end of abdomen.

Legs: Slender and long. Unarmed. Sparsely covered with short bristles. Anteroventral and posteroventral carinae of femora with one to four small spines subapically. Profemora incurved basally. Medioventral carina of tibiae weakly elevated basally.

Wings: Tegmina scale-like, small and indistinct. Alae small, oval, shorter than pronotum, costal region brown, anal region red, posterior apices not reaching middle area of median abdominal segment.

Male. (Figs. 126–127, 159–161, 163). Medium-sized. Body slender, smaller and more slender than female. General colour of body and legs dull greenish brown.

Head: Oval, with sparse and inconspicuous granulations. Vertex flat, unarmed. Occiput flat, posterior margin with six small swellings. Compound eyes small and oval. Antennae long and filiform; scapus flattened basally, as long as third segment, longer than pedicellus.

Thorax: Sparsely covered with small and inconspicuous granules. Pronotum rectangular, transverse and longitudinal sulci crossing before middle point, anterior margin curved inwards, posterior margin rounded. Mesonotum with two to three black spines along each side of median longitudinal line. Metanotum unarmed, almost as long as median segment.

Abdomen: Slender. Eighth tergum expanded posteriorly, as long as ninth tergum. Anal segment shorter than ninth tergum, posterior margin thickened and with a broad V-shaped emargination. Poculum cup-shaped, posterior margin rounded, reaching anterior area of anal segment. Cerci cylindrical, weakly curved inwards, apices rounded and surpassing posterior margin of anal segment.

Legs: Slender and long. Sparsely covered with short bristles. Femora roughly as long as corresponding tibiae, anteroventral and posteroventral carinae of femora with two to four small spines subapically. Profemora distinctly curved at base. Mesofemora shorter than mesonotum.

Wings: Tegmina scale-like, small and indistinct. Alae short, oval, costal region yellow and black, anal region red.
