Ectatosticta yukuni Lin & Li, 2021: 7 , figs 4A–C, 6B, 7G–H (♂ ♀).

Material examined. 1 male and 1 female, China, Shaanxi Province, Hanzhong City, Lueyang County, Wulongdong Town , 33°36′22″ N, 106°18′20″ E, elev. 1754 m, 1 June 2013, X.W. Meng leg. ; 1 female, Lueyang County, Wul- ongdong Town , 33°36′22″ N, 106°18′20″ E, elev. 1754 m, 18 October 2020, L.Y. Wang, Y. Zhang, J.X. Zhao and J.S. Luo leg.

Diagnosis. The male of this species resembles E. bajie Lin & Li, 2021 ( Figs 5A–C , 15A , 16A ) in having five strong setae on cymbial lobe, but differs from the latter by the narrow conductor base and flat apical edge of the embolic base ( Figs 14A–C , 15K , 16K ). The female of this species resembles E. deltshevi Platnick & Jäger, 2009 ( Fig. 17D ) in having two pairs spermathecae and ventral spermathecae two times longer than dorsal spermathecae, but differs from the latter by the thin ventral spermathecae ( Fig. 18F ).

Description. See Lin & Li (2021). Habitus, male palp and female genitalia as in Figs 4E–F , 14A–C , 15K , 16K , 18F .

Distribution. China (Shaanxi) ( Fig. 19 ).
