Type material examined. Holotype of Polyphaga yunnanensis, male (MNHN, No. 742), CHINA: Yunnan: “MUSEUM PARIS/ YUN-NAN/ TSÉ-KOU/ (M gr SOULIÉ)/ R. OBERTHUR, 1897”, with a determined label: “ Polyphaga yunnanensis type Chop. (Handwritten)/ L. CHOPARD. det.”.
Diagnosis. This species superficially resembles E. thibetana, but can be distinguished from the latter by the following characteristics: 1) interocular space narrower than the distance between ocelli (Fig. 14 B–C), while interocular space as wide as the distance between ocelli in E. thibetana (Fig. 14 E–F); 2) lateral corners of subgenital plate round, similar (Fig. 22 B), while lateral corners of subgenital plate more irregular and dissimilar in E. thibetana (Fig. 23 B); 3) L2 thin (Fig. 22 C), while L2 thick in E. thibetana (Fig. 23 C); 4) R2 chunks round (Fig. 22 D), while R2 chunks quadrate in E. thibetana (Fig. 23 D).
Redescription. Male. General: measurements (mm): body length: 17.2–29.3, overall length: 26.2–36.4, pronotum length×width: 4.9–6.9×7.9–11.2, tegmen length: 22.5–31.4. Body small to large, pale yellow to light yellowish brown, with brown maculae on tegmina (Fig. 6 J–M). Head: vertex dark brown. Interocular space moderate, narrower than the distance between ocelli; ocelli white, large, inter-ocelli ridge pubescent. Frons brown to dark brown, flat, posterior of frons pubescent. Antennae brown, next to the antennal sockets with two elongated grooves. Clypeus wide; ante-clypeus whitish yellow; post-clypeus brown. Labrum brown, apex white, bluntly rounded. Maxillary palpi and labial palpi brown, with joint parts white (Fig. 14 B–C). Pronotum: yellowish brown, anterior with whitish yellow margin, subtransparent. Surface generally with small yellowish pubescence, anterior and lateral margins with additional long brown setae. Apex of anterior margin slightly arched, lateral fore borders angled, and then slightly convex and oblique, becoming straight and oblique towards the hind middle, hind margin slightly convex (Fig. 14 A). Tegmina and wings: extended the end of abdomen about 8.7–14.1 mm. Tegmina hyaline, whitish yellow, with scattered brown speckles, the speckles irregular, usually consisted by many very tiny irregular spots and several large irregular speckles, venation light brown. Wings hyaline, venation light brown, apex and CuA areas usually with some pale brown maculae. Legs: light yellowish brown, covered with long yellow pubescence; tibial spines reddish brown. Abdomen: brown to dark brown, smooth, with a few short pubescence. Supra-anal plate pubescent, transverse apex protruded; cerci short; two median sclerites minute (Fig. 22 A). Subgenital plate with median concave; styli similar, the right one larger than the left (Fig. 22 B). Genitalia: well sclerited. Left phallomere: small. L1 with anterior part protruded, one of the hind lobes strong; L2 very thin, curved roundly, right end with two slender processes; L3 short, the hook curved roundly. Right phallomere: large. R1M robust, posterior part enlarged, transparent; R1L thin; R3 with hind median widely transparent; R2 small, with irregular round chunks (Fig. 22 C–D).
Female. Measurements (mm): body length: 17.7–29.5, body width: 11.8–19.0, small to median. Generally, unicoloreduncolored, yellowish brown to dark brown depending on specimen, pubescent; two eyes connected by a row of pubescence, supra-anal plate protruded type, median with a longitudinal line (Fig. 6 N–Q).
Nymphs. Similar to the female.
Ootheca. As Fig. 38 J and R, reddish brown, serration of keel very small, triangular. The longitudinal ridges shallow, not very distinct.
Natural history. This species lives around human dwellings in west China (Fig. 42 E–F), it can also be found beneath the dry sand and rock under trees (Fig. 42 A–C), or inside the humus under the roadside cliff (Fig. 42 H), or beneath the leaves in the forest (Fig. 42 D), males may rest on the bush branch at night (Fig. 42 G).
Distribution. China (Tibet, Sichuan, Yunnan, Gansu, Neimenggu, Qinghai, Guizhou, Jiangxi, Guangxi) (Fig. 2).
Remarks. A species mainly occurs in the high lands of China (East Tibet, West Sichuan, South Qinghai and Gansu, and Northwest Yunnan). The highest altitude of their living environment is up to 4000 m. The adaption to the tough environment makes it widely distributed in west China. Besides, several specimens from the low altitude areas are also examined by us (viz. Jiangxi, Guangxi, and Guizhou), which indicates this species also rarely and scatteredly occurs in central and south China.
