Diagnosis.
Females of E. xuanzang sp. nov. can be distinguished by the ratio of the length of the inner spermathecae to the outer spermathecae of almost 1:3 (Figs 5D View Figure 5 , 6G-K View Figure 6 ) (vs. almost 1:1 in E. davidi and 1:2 to 1:1 in E. deltshevi (Figs 5A, B View Figure 5 , 6A-C, F View Figure 6 )) and the ratio of leg I length to the carapace length is almost 1:8 (vs. almost 1:6 in E. wukong sp. nov. and E. deltshevi and 1.7 in E. davidi ).
Description.
Female. Total length 12.59, carapace 6.03 long, 3.60 wide, opisthosoma 6.22 long, 4.40 wide. Eye sizes and interdistances: AME 0.15, ALE 0.31, PME 0.29, PLE 0.28, AME-AME 0.19, AME-ALE 0.37, PME-PME 0.42, PME-PLE 0.27, AME-PME 0.07, ALE-PLE 0.06. Clypeus height 0.45. Chelicerae with seven (n = 3) or eight (n = 3) promarginal and 6-9 (6(n = 1), 7(n = 4), 9(n = 1)) retromarginal teeth. Leg measurements: Leg I: 51.47 (15.45 + 16.28 + 12.95 + 6.79), leg II: 47.88 (14.03 + 16.22 + 11.60 + 6.03), leg III: 37.66 (11.67 + 12.50 + 9.04 + 4.45), leg IV: 44.23 (12.31 + 14.49 + 12.11 + 5.32). Leg formula: 1243.

Male.
Unknown.
Distribution.
Known only from the type locality.
National history.
In damp rocky areas, hiding between huge stones. They build simple sheet webs without a tube-retreat.
