Holotypes: ♂, paratypes 12 ♂, 12♀, China, Shanxi, Luyashan , (44°11’N, 80°54’E), 1,000–1,400 m, 8.VII.2011 collected by Wang Peng-Xiang and Zhi Yong-Chao. GoogleMaps  

Male ( Figs. 1–4 View FIGURES 1–9 ). Body small. Head slightly shorter than pronotum. Frons oblique in profile, frontal ridge with longitudinal groove; lateral margins of frontal ridge nearly parallel before median ocellus and gradually widened toward clypeus. Apex of vertex rounded and blunt with distinct median carina. Fastigial foveolae absent. Antennae ensiform, longer than head and pronotum together, middle segments about 1.8 times as long as wide. Eyes oval, longitudinal diameter about 1.5 times as its horizontal diameter and 1.4 times as long as subocular furrow. Pronotum tectiform, anterior margin straight, posterior margin curved. Median carina and lateral carinae of pronotum distinct, lateral carinae thicker and curved slightly; posterior transverse sulcus situated behind the middle part of pronotum, length of prozona 1.5 times as long as metazona; anterior transverse and median transverse sulci faint in dorsal view, posterior transverse sulcus distinct. Length of mesosternal interspace 1.5 times its minimum width; metasternum lobes separated. Tegmen short, reaching to 2/3 of hind femur; apex of tegmen concave medially; maximum width of cubital vein area 1.5 times median vien area. Basal part of femoral stridulatory file forms double lines, teeth cone-bulging, apex rounded shaped. Apex of lower kneelobe rounded. Hind tibia with 12 spines on outer side and 11 spines on inner side, without outer apical spine, first segment of hind tarsus distinctly longer than third segment. Arolium wide, slightly surpassing apex of claws. Tympanal organ present, oblong, oval. Epiproct triangular, basal part with median longitudinal groove. Furculae large. Cercus long, conical, apex almost reaching to apex of epiproct. Subgenital plate short conical, slightly narrowed toward apex. Epiphallus bridgeshaped; anchorae flexed, pointed; inner lophi small, rounded; without acute projection on both sides.

Female ( Figs. 5–9 View FIGURES 1–9 ). Body more robust than that of male, medium size. Antennae sharply ensiform, not reaching posterior margin of pronotum, basal segment distinctly widened, middle segments about 1.1 times as long as wide. Eyes small, longitudinal diameter slightly shorter than subocular furrow. Prozona of pronotum about 1.9 times longer than metazona. Length of interspace of mesostermum 1.6 times minimum width. Tegmen squamiform, widely separated in dorsal view, apex slightly extending beyond first abdominal tergum. Abdominal terga with median longitudinal carina. Cercus short, twice as long as wide, extending not to apex of epiproct. Ovipositor valves slender, outer margins of dorsal valves and ventral valves with fine denticles. Posterior margin of subgenital plate with angularly projection in middle part.

Coloration. Body yellowish brown. Antennae yellowish brown. Vertex with dark stripe running from eyes to joint between vertex to pronotum. Tegmen dark brown, anterior margin with white stripe. Hind femur dark brown on outer side, genicular lobe yellow brown. Hind tibia yellow.

Measurement (in mm). Length of body: ♂ 16.7–18.8; ♀ 25.9–26.3. Length of tegmina: ♂ 8.3–9.6; ♀ 2.9–3.6. Length of hind femur: ♂ 10.2–10.3; ♀ 11.5–12.1.

Diagnosis. The new species is similar to Confusacris brachypterus Yin & Li, 1987   , The major differences are listed in Table 1.

Etymology: The specific epithet is named for Shanxi, the type locality.
