(叶ª尧奇e) Figs 115–134 Type material. Holotype : ♂ ( MHBU-ARA-00023389 ), CHINA : Yunnan Province , Dali City , Jisheqing Water Reserve ( ḚZÎ保ḁ区 ), 25.7369°N , 100.1241°E , 2164 m elev., 13 July 2021 , leg. J. Zhang. Paratypes : 2♂ 2♀ ( MHBU-ARA-00023423 ), same data as holotype . Etymology. The specific epithet is derived from the ancient name of Dali City: Yeyu City ( 叶dzẅ ). Noun in apposition. Diagnosis. The new species closely resembles E . ailao sp. nov. , E . yangmei and E . shenjun in the genital morphology, but can be distinguished by: (1) the embolus straighter in ventral view; (2) the thinner RTA in retrolateral view; (3) the white setae on the carapace concentrated in certain area, rather than scattered around; (4) the spermathecae almost equal in length and width, smaller than 1/2 of the epigynal window in ventral view.
