( Figs. 10 E–F; 15 J–L; 29 A–D) Type material. Holotype : CHINA : Yunnan : 1 male (SWU), Mt. Zixishan [紫溪山], Chuxiong City [楚雄市], 2397m , trapped by a flashlight, 7.VII.2012 , Dong Wang leg. Paratypes : 11 males ( SWU , 6 are preserved in 100% alcohol), same data as the holotype . Diagnosis. This species is similar to E. maculata sp. nov. , but can be distinguished from the latter by the following characteristics: 1) body pale brownish, while body brownish yellow in E. maculata sp. nov. ; 2) body larger (overall 26.1–27.7mm ), while body smaller (overall 24.4–24.8mm ) in E. maculata sp. nov. ; 3) pronotum brown, anterior margin yellowish, margins rounded, while pronotum yellow, only median with a spotted marking, margins angular in E. maculata sp. nov. Description. Male. General: measurements (mm): body length: 12.6–16.4, overall length: 26.1–27.7, pronotum length×width: 4.3–4.8×7.1–7.9, tegmen length: 22.5–24.4. Small, slender; body short, dark brown, tegmina hyaline, sparsely spotted ( Fig. 10 E–F). Head: brown to dark brown. Interocular space narrow; ocelli moderate, ocelli ridge straight. Frons flat, with two shallow dimples. Antennae dark brown. Clypeus small; anteclypeus yellow; post-clypeus brown to dark brown, with two yellow spots laterally. Labrum brown, apex white, hind corners round. Maxillary palpi and labial palpi dark brown (Fig. 15 K–L). Pronotum: brown, anterior margin yellow, but strongly maculated. Surface generally with small brownish pubescence and setae, anterior and lateral margins not distinctly setose; margins rounded, not distinctly angular, apex slightly convex and truncated, lateral borders round (Fig. 15 J). Tegmina and wings: exceeded the end of abdomen about 11.1–13.3 mm . Tegmina hyaline, light brownish yellow, sparsely with small, scattered brown spots, several larger spots among the small spots. Wings hyaline, slightly dotted, venation distinct. Legs: dark brown, mixed with yellowish coloration. Surface covered with long yellowish-brown pubescence; tibial spines dark brown. Abdomen: short, smooth, dark brown, disorderly with some yellowish spots, a yellow trail longitudinally through the median of abdomen. Supra-anal plate well pubescent, apex protruded; two median sclerites large, cerci slender ( Fig. 29 A ). Subgenital plate brown but slightly yellowish for the exposed part, median usually slightly maculated, hind margin near straight, setose; styli small ( Fig. 29 B ). Genitalia: well sclerotized. Left phallomere: Anterior of L1 much protruded, round, with a long process toward left, two hind lobes strong; L2 thin, curved roundly, right end wrench-like; L3 straight, strong narrowed toward apex, the hook curved roundly or slightly rectangularly; pda short, paa bud like; L8 small. Right phallomere: large. R1M narrow, hind portion expand; R1L thin; R3 concave; R2 with two chunks, the outer one rounder, the inner one with median concave and narrowed ( Fig. 29 C–D). FIGURE 26.

Unknown. Ootheca. Unknown. Variation. Males mainly vary in the following characters: 1) the density of brown spots in the hyaline area of pronotum; 2) the density of spots on the tegmen. Etymology. This species is named in honour of the Chinese entomologist Ping-Zhang Feng, who did much contributions to the knowledge of Chinese cockroaches. Natural History. The types were all accidentally trapped by a flashlight during night searching at Mt. Zixishan (Dong Wang, personal communication). Distribution. China ( Yunnan ) ( Fig. 3 ).
