Diagnosis. This species resembles E. aenea, E. forceps, E. coerulea, and E. gemma by having two spots on the lateral margins of tegmina, but it can be distinguished from E. aenea and E. forceps by the arrangement of the white pubescence (band shaped in E. linglong, while circle-shaped in E. aenea and E. forceps); it differs from E. coerulea by the white pubescence (with white pubescence in E. linglong while without in E. coerulea); it can be distinguished from E. gemma by the larger body size (more than 10 mm without tegmina in E. linglong, while less than 10 mm in E. gemma).
Description
Male: measurements (mm): body length 11.0–12.4, overall length 12.5–15.8 (including wings), pronotum length×width 3.3–3.9×5.1–6.0, tegmen length 9.1–11.7. Small, metallic bluish green to deep blue (Fig. 7L–M). Head shiny, metallic black; antennae (except the whitish segments distally), maxillary palpi and labial palpi brownish black. Pronotum metallic bluish green to deep blue, with black long setae, usually with some white pubescence. Tegmina bluish green to deep blue, blackish toward apex, each lateral margin with an orange spot, tegmina with white pubescence basally, the space between the two orange spots with a strip of white pubescence; wings hyaline, venation brown, distinct. Legs dark brownish black, with brown pubescence, spines on the legs dark brown, with apex reddish brown.
Abdomen in ventral view, the last four sternites (including subgenital plate) dark brown, slightly metallic, the rest with lateral portions orange, median blackish; in dorsal view, the last five terga (including supra-anal plate) black, the rest of terga purplish black but with the three orange lateral portions. Supra-anal plate with hind median roundly concave, lateral hind corners round, cerci short (Fig. 8A); subgenital plate with two long styli. Genitalia (Fig. 8A): L3 curved, the apex hook with curved part protruded, left base of appendage sclerite with an elongate and sharp process, hind apex with a sharp elongation, R2 elongate, each apex round.
Female: overall length 12.7 mm, similar to male, but with short tegmina which extends only slightly beyond the end of abdomen (Fig. 7N–O).
Etymology
The specific epithet “linglong [玲珑]” means small and elegant in Chinese, in reference to its small and gorgeous body.
Remarks
The female paratype was captured in the karst environment from Guangxi (Fig. 14C–D). This species is also distributed in Vietnam, as seen in a photo taken by Mr. E. Jendek (Fig. 14B); the photo information is: “Cuc-Phuong National Park, 20°21'58.0"N, 105°35'31.0"E, 27.IV.2012, E. Jendek photoed”. A male individual has also been photographed by Mr. Jin Chen from Manhao [蔓耗镇], Gejiu City [个旧市] in Yunnan (Fig. 14A).
Natural history
A male was found on the ground by accident during a rainy day in Manhao, Yunnan (Fig. 14A, Jin Chen, pers. comm.). The female paratype was collected by Mr. Yi-Zhou Liu from a pile of wood (Fig. 14C).
Distribution
China: Hainan, Yunnan, Guangxi, Guizhou; Vietnam: Hoa Binh.
