Ectatosticta rulai Lin & Li, 2021: 6 , figs 3A–C, 6A, 7E–F (♂ ♀). Material examined. 1 male and 3 females, China, Sichuan Province, Jiuzhaigou County, Jiuzhaigou Town , 33°17′07″ N, 103°56′46″ E, elev. 2098 m, 24 September 2012, L.Y. Wang leg.; 1 male, Sichuan Province, Pingwu County, Wanglang Nature Reserve, Baixionggou , 33°00′10″ N, 104°01′31″ E, elev. 2795m, 25 September 2019, L.Y. Wang leg.

Diagnosis. The male of this species resembles E. deltshevi Platnick & Jäger, 2009 ( Figs 7A–C , 15C , 16C ) in having two strong setae in cymbial lobe, but differs from the latter by the long embolic base and the strong conductor ( Figs 10A–C , 15F–G , 16F–G ). The female of this species resembles E. wukong Lin & Li, 2020 ( Fig. 18D ) in having one pair of spermathecae, but differs from the latter by the strong spermathecae base ( Fig. 18A ).

Description. See Lin & Li (2021). Habitus, male palp and female genitalia as in Figs 2A–D , 10A–C , 15F–G , 16F–G , 18A .
