Type material. Holotype: male, CHINA, Yongshan County, Yunnan Province, 28.1694° N, 103.5996° E, 1576 m, 20 Aug. 2024, coll. Xun Wang, Honglei Yu, Hong Song, Fangting Li. Paratypes. 3 males, 2 females, data same as holotype. Type specimens are deposited in the BMDU .

Diagnosis. This new species is similar to C. chinensis and C. yunnanensis . The major differences are listed in Table 1.

Etymology. The specific epithet refers to the type locality.

Description. Body median in size, stouter in female.

Head. Head shorter than pronotum; vertex with fastigium broad, obviously sloping anteriorly, nearly flat in dorsal view, anterior margin broadly rounded, in front of eyes with a transverse impression; interocular distance broad, 2.3–2.9 (mean 2.7, n=4, male) or 2.0–2.2 (mean 2.1, n=2, female) (the same below) times width of frontal ridge between antennae. Face sloping; frontal ridge with shallow longitudinal sulcus; lateral margins nearly parallel. Lateral facial keels thick and straight. Antennae filiform, exceed posterior margin of pronotum, median 6 th –10 th segments about 1.8–2.7 (2.3, male) or 1.9–2.7 (2.3, female) times as long as wide. Eyes oval, longitudinal diameter about 1.4–1.5 (1.4, male) or 1.5 (female) times as long as horizontal diameter, and about 1.8–2.7 (2.3, male) or 1.9–2.7 (2.3, female) times as long as subocular furrow.

Thorax. Pronotum in both genders nearly quadrangular prism shaped, surface wrinkled and punctured, denser in metazona; anterior margin nearly straight, weakly incised in middle; posterior margin obtuse-angularly protruding and slightly concave at the middle; dorsum slightly tectiform, median carina thick, clearly cut by posterior transverse sulcus; lateral carinae thick, nearly straight, retrad expanded; three transverse sulci distinct; prozona 1.4–1.6 (1.5, male) or 1.4 (female) times as long as metazona; lateral lobe with posterior margin slightly concave, posteroventral corner nearly obtusely angular. Prosternal spine stout and conical, apex subacuate. Mesosternal interspace nearly trapezoid, length about 1.0–1.5 (1.2, male) or 1.4–1.9 (1.6, female) times shorter than minimum width; metasternal lobes separated. Tegmina lateral, oval, length 1.3–1.4 (1.4, male) or 1.1–1.3 (1.2, female) times larger than maximum width, apex surpassing posterior margin of 2 nd abdominal tergite. Hind femora with upper carina smooth; apex of lower knee lobes rounded. Hind tibiae with internal and external apical spines, 10–12 external and 10–11 internal spines on dorsal side.

Abdomen. Abdomen tergites with median carina. Tympana opening distinct, oval.

Male genitalia. Tenth abdominal tergite widely divided in middle, hardly having furculae. Epiproct broad shield, length larger than width; with a curved transverse furrow in middle area and a broad median longitudinal sulcus in basal half, lateral areas concaved; posterior margin straight in both sides, triangularly projecting in middle. Cerci surpassing apex of epiproct, compressed laterally, broader on basal and apical parts, and narrower in middle part, apex with middle area slightly concave, apical margin obliquely excised, postero-upper angle nearly round, postero-lower angle obtusely angular. Subgenital plate short conical, apex rounded. Epiphallus with bridge arched; lophi with dense granules, near quadrilateral in posterior view, postero-inner angle roundly protruding, postero-outer angle nearly round; ancorae triangular and compressed, ventrad rolled, apex pointed, far away anterior projections. Phallic complex: apical valves of penis divided into dorsal part and ventral part, apex acute in lateral view; a appendant dorsal sclerite of ectophallus membrane with posterior margin sinuated.

Female genitalia. Epiproct nearly quadrilateral, with a curved transverse furrow in the middle and a middle longitudinal sulcus in the basal half. Cerci conical, apex blunt, not reaching apex of epiproct. Subgenital plate width larger than length, posterior margin rounded, with two large teeth in both sides and a small one in the middle. Valves of ovipositor with blunt dentes along margins.

Coloration. The following notes according to fresh specimens. Body generally yellowish brown (male) or brownish yellow (female). Head yellowish brown (male) or light yellowish brown (female) except postocular bands black and eyes brownish, with a triangular black spot on dorsum; antennae with 10 th, 12 th, 14 th, 16 th, 18 th –21 th black,

others yellowish white; postocular bands black, continued on pronotum, tegmen and abdomen. Pronotum with disc blackish brown in male, grayish brown in female; lateral carinae yellowish; lateral lobes under lateral carinae with Y-shaped black strips. Tegmina blackish brown, anal area yellowish. Hind femora brown on upper side, with two black spots; outside yellow, with three black spots; lower side blue; inside yellowish, with a large black stripe and a little black spot; knee brown; hind tibiae blue or yellowish, base black, near the base with light ring. Abdominal tergites yellowish or gray with black longitudinal stripes in both sides.

Measurements (mm). Body length: male 27.4–29.2, female 32.3–37.7. Pronotum length: male 7.0–7.5, female 8.0–9.3. Tegmen length: male 5.5–6.1, female 7.6–8.0. Hind femur length: male 15.3–15.8, female 18.7–19.0.

Distribution. China: Yunnan.

Biology. C. yongshanensis sp. nov. mainly feed on Argentina lineata (Trevir.) Soják , which grows in the wet and halfshady zone at medium elevation (1500 m) in Yunnan.
