Type material.

Holotype ♂ (IZCAS-Ar40346), China, Sichuan Province, Hongyuan County, Shuajingsi, Mt. Zhegu to Shuamalukou, 31.9272N, 102.6546E, elevation ca. 3458 m, 23.XI.2019, Zhigang Chen leg. Paratypes 3♀ (IZCAS-Ar40347-Ar40349), same data as holotype.

Etymology.

The species is named after Wukong, a character in the classic Chinese novel Journey to the West, noun. Journey to the West was written during the Ming Dynasty (1368-1644 A.D) and is about the adventures of a priest, Xuanzang, and his three disciples, Wukong, Wuneng, and Wujing, as they travel west in search of the Buddhist Sutra. Their travel begins at what is today Xi'an (near the type locality of E. davidi ), via Qinghai (close to the type locality of E. deltshevi ), to South Xinjiang, Tibet (near the type locality of E. xuanzang sp. nov.) and India.

Diagnosis.

Males of E. wukong sp. nov. can be distinguished by having only two thickened setae retrolaterally on the cymbium and the length ratio of the embolus to the embolus base is almost 3: 1 (Fig. 3C, D View Figure 3 ). Females can be distinguished by having one pair of spermathecae (Figs 5C View Figure 5 , 6D, E View Figure 6 ).
