Type material: Holotype male in UBC-SEM from CHINA: Guangxi: Pingxiang City, Daqingshan Park. N 22°07’18” E 106°43’59”, 247m, 14 May 2006. J.X. Zhang, M.S. Zhu, W.G. Lian, H.Q. Ma, (JXZ06#004). Paratypes: 1 male and 1 female, same data as holoype.

Etymology. In an old Chinese story, the emperor's daughter Jingwei died at sea to be reborn into a bird who, in revenge, attempted to fill the sea with pebbles.

Diagnosis. Differs from E. prima and E. nezha in the robust and relatively straight patellar apophysis in the male palp. The median apophysis is relatively smaller than in those two species. The female differs from the other species in details of the epigynum.

Description. Male: Total length 1.8–1.9. Holotype total length 1.8: carapace 1.0 long, 0.8 wide, 0.5 high; abdomen 0.9 long, 0.6 wide. Carapace ( Fig. 12 ) dark brown with eye region dark, and a triangular yellow brown patch from between PLEs to posterior end of carapace. Clypeus ( Fig. 11 ) yellow brown, with lots of long white hairs. Eye sizes: AME 0.26, ALE 0.18, PME 0.04, PLE 0.14. First eye row 0.94 wide, second eye row 0.72 wide, third eye row 0.76 wide, eye area 0.50 long. Clypeus height 0.12. Fovea absent. Chelicerae small and yellow, with front face gray, promargin with two teeth, retromargin with three teeth and two denticles, both margins with long setae. Endites and labium yellow brown. Sternum gray brown with many yellow speckles. Femora, patellae and tibiae gray, with yellow longitudinal stripes. Other segments yellow brown, with gray pigments. Metatarsus I with three pairs of ventral spines and tibia I with two pairs of ventral spines. Measurements of legs: I 1.8, II 1.6, III 1.5, IV 2.2. Leg formula: 4123. Abdomen ( Fig. 12 ) dark with dorsal scutum, front margin with a few long setae, venter with a yellow longitudinal band behind genital groove. Palp ( Figs 8–10 ): Similar in structure to that of E. nezha , although the tegular apophysis is relatively longer, the median apophysis smaller, and the patellar apophysis more robust.

Female: Total length 2.5; carapace 1.2 long, 1.0 wide, 0.6 high; abdomen 1.2 long, 1.1 wide. Carapace and abdomen coloration and patches similar to those of male. Clypeus dark brown with yellow brown patches. Eye sizes: AME 0.28, ALE 0.20, PME 0.04, PLE 0.14. First eye row 0.96 wide, second eye row 0.74 wide, third eye row 0.86 wide, eye area 0.58 long. Clypeus height 0.12. Measurements of legs: I 1.8, II 1.5, III 1.6, IV 2.4. Leg formula: 4132. Epigynum ( Fig. 13 ): Difficult to interpret, with two circular areas that we presume include the openings, lying anterior to a shield that overlaps the epigastric furrow.
