Eupolyphaga fengi sp. nov.

( 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).

Female. Unknown.

Nymph. 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 ).
