( Figs. 10 I–P; 16 G–I; 37 A–D; 38 G, O; 45 A–H)

Type material. Holotype: CHINA: Yunnan: male (SWU), beside S307 road, Xiaohebian Stream [小河边沟], Yaonan Village [耀南村], Mt. Ailaoshan [哀牢山], Xinping County [新平县], Yuxi City [玉溪市], 1955m, 11.V.2016, Lu Qiu & Zhi-Wei Qiu leg. Paratypes: 5 females ( SWU, 3 in 100% alcohol), same data as the holotype ; 1 male ( SWU), Changning County [昌宁县], Baoshan City [保山市], 1850m, 23.VI.1980 , no collector recorded; 1 male ( SWU), Changning County, Baoshan City , 1650m, 25.VI.1980 , no collector recorded; 1 male ( SWU), Shili Township [诗礼乡], Fengqing County [凤庆县], Lincang City [临沧市], 1800m, 7.VII.1980, Fu Zhang leg. ; 1 male ( SWU), Liujiegongshe (now Liujie Town ) [六街镇], Jinning County [晋宁县], Kunming City , 1960m, 16.VII.1980 , no collector recorded.

Other material examined. Several nymphs and oothecae (SWU, nymphs all preserved in 100% alcohol), same data as the holotype.

Diagnosis. Resembles E. pilosa sp. nov. by the similar maculae pattern on tegmina in male, but differs from the latter by the much narrower anterior margin of pronotum (usually indistinct, some individuals nearly disappeared, while narrow but clear in E. pilosa sp. nov.), larger body size (male body length 17.8–20.1 mm, female 19.3–20.2mm; while male body length 15.6–16.8mm, female 15.2–17.6mm in E. pilosa sp. nov.), and pronotum with setae (while with long hair in E. pilosa sp. nov.).

Description. Male. General: measurements (mm): body length: 17.8–20.1, overall length: 28.1–31.5, pronotum length×width: 4.9–5.2×7.5–7.8, tegmen length: 23.9–27.6. Median to large, slender. Ventral surface chocolate, tegmina maculated ( Fig. 10 I–L). Head: blackish brown. Interocular space moderate, ocelli large, ocelli ridge slightly curved. Frons wrinkled. Antennae yellowish brown. Clypeus distinct, lateral borders yellowish, anteclypeus yellow, post-clypeus brown. Labrum brown, wide, apex distinctly emarginated. Maxillary palpi and labial palpi brown ( Fig. 16 H–I). Pronotum: brown to dark brown, anterior with a very narrow whitish margin, sometimes reduced. Surface generally with many small brownish pubescence and setae, lateral and anterior margins with long setae additionally. Anterior margin with apex strongly concave, lateral fore borders round, then becoming straight, hind margin convex ( Fig. 16 G ). Tegmina and w ings: exceeded the end of abdomen 9.6–12.1 mm. Tegmina hyaline, light yellowish brown, scatter with small, distinct and brown spots, several large spots distributed among the small spots, outer margin at the base usually strong maculated. Wings hyaline, light brown, apex slightly maculated. Legs: brown to blackish brown, long haired; tibial spines brown. Abdomen: pubescent, lateral portions dimly yellowish brown, median and the apex dark brown to blackish brown. Supra-anal plate well pubescent, apex slightly protruded; two median sclerites large, cerci slender ( Fig. 37 A ). Subgenital plate unicolored, brown to blackish brown for the exposed part, slightly asymmetrical, right portion lager than the left, hind margin concave; styli similar, small but long ( Fig. 37 B ). Genitalia: well sclerotized. Left phallomere: small, L1 round anteriorly and with a small process towards left, media of L1 narrow, two hind lobes wide apart; L2 slender, right with two processes, wrench like; pda and paa elongate and straight; L3 gradually narrowed, the hook part bend roundly; L8 irregular. Right phallomere: large, in right-ventral view, R1M with enlarged and transparent hind portion; R2 with two large chunks ( Fig. 37 C–D).

Female. Measurements (mm): body length: 19.3–20.2, body width: 13.2–14.5. Generally, with two color type, viz. the brown type ( Fig. 10 M–N) and the black type ( Fig. 10 O–P), body round, maculated. Head black, the areas around eyes and antennal sockets yellowish, ante-clypeus yellowish white, labrum yellow, slightly brownish, maxillary palpi and labial palpi brown. Pro-, meso- and metanotum setose, dark brown to black. Legs brown to blackish brown, with joint parts yellow. Abdomen terga with median and lateral dimly yellowish; sternites brown to brownish black, median with a weak longitudinal yellowish line. Supra-anal plate small, slightly protruded, median of distal margin with a small emargination. Subgenital plate protruded type, bulged.

Nymph. The markings on the body more distinct and coloration lighter than the adult female.

Ootheca. As Fig. 38 G and O , reddish brown, serration of keel small, curved, triangle shape, apex blunt. Respiratory canals invisible. The longitudinal ridges distinct.

Etymology. This species is named in honour of the Chinese entomologist Fo-Ching Woo (Fu-Zhen Wu), for his contributions to Chinese cockroach study.

Natural History. Females, nymphs and oothecae were found in shallow holes beside the mountain road in Mt. Ailaoshan, the holes usually fulfilled by dead leaves, detritus, or sandy soil ( Fig. 45 A–G).

Distribution. China (Yunnan) ( Fig. 3 ).

Remarks. Plenty living females and nymphs were collected by the first author and Mr. Zhi-Wei Qiu from Mt. Ailaoshan, but we only obtained one adult male from the nymph ( Fig. 45 H ), the rest all died mysterious. Fortunately, four male specimens of the species were found from the old collection of SWU, which were collected from several localities in Yunnan.
