Hypochilus davidi Simon, 1889: 208 .

Ectatosticta davidi: Simon 1892: 204 , figs 143–146, 148–149 (♂ ♀); Gertsch 1958: 13, figs 10, 19, 22–31 (♂); Lehtinen 1967: 431, fig. 15 (♂); Platnick & Jäger 2009: 210 , figs 1–4 (♂ ♀); Zhang & Wang 2017: 311, 4 f. (♂ ♀); Lin & Li 2020: 19 , figs 1, 2A, 3A, 4A, 5A, 6F (♂ ♀).

Material examined. 5 males and 20 females, China, Shaanxi Province, Xi’an City, Chang’an District, Xiaoyuhe , 33°57′13″ N, 109°3′39″ E, elev. 1300 m, 22 October 2020, L.Y. Wang, Y. Zhang, J.X. Zhao and J.S. Luo leg.

Diagnosis. This species resembles E. yukuni Lin & Li, 2021 ( Figs 14A–C , 15K , 16K , 18F ) in having wide and sickle-shaped conductor, five strong setae on cymbial lobe and two pairs of long spermathecae (ventral and dorsal ones), but differs from the latter by the wide conductor base, the strong embolic base ( Figs 6A–C , 15B , 16B ), and the ventral spermathecae almost twice as long as dorsal spermathecae ( Figs 17B–C ).

Description. See Platnick & Jäger (2009). Habitus, male palp and female genitalia as in Figs 1A–E , 6A–C , 15B , 16B , 17B–C .

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