Figs 7–9 , 62 urn:lsid:zoobank.org:act: AB933205-EFDB-4490-A073-52CBB8EDDC04 Type material. Holotype male: CHINA : Hunan Province : Hengyang City , Hengyang County , Hengshan Scenic Area , 27.28°N , 112.70°E , 610 m , native forest, 25 June 2017 , Y. Zhong & Y. Zhu leg. (CBEE). Paratypes : 1 male and 2 females ( CBEE ) , 1 female ( SMF ), with same data as holotype . Etymology. The specific name is derived from the Latin adjective apiculiformis , -is , - e , meaning “apiculiform” referring to the tip of dorsal retrolateral tibial apophysis apiculiform. Diagnosis. Males of S. apiculiformis sp. nov. resemble those of S. aequalis sp. nov. ( Figs 4 A–C, 5A–D), S. luyui sp. nov. ( Figs 40 A–C, 41A–D) and S. pengi Song & Zhu, 1999 ( Song et al. 1999 : fig. 270N) in a similar general palpal conformation, especially the embolus tip as long as embolic apophysis and the tegulum covering the proximal part of embolus. Males can be distinguished from S. aequalis sp. nov. , S. luyui sp. nov. and S. pengi by: dRTA three times as long as vRTA in retrolateral view (two times in S. aequalis sp. nov. , S. luyui sp. nov. and S. pengi ); cymbium slightly longer than tibia (distinctly longer in S. aequalis sp. nov. , S. luyui sp. nov. and S. pengi ). Females of S. apiculiformis sp. nov. are similar to those of Sinopoda horizontalis Zhong, Cao & Liu, 2017 ( Zhong et al . 2017 : figs 5A–B, 6A–B) in having slender anterior bands and posterior margin of epigyne distinctly bilobate, but differ from S. horizontalis by: glandular appendages as wide as posterior parts of spermathecae, with ends not modified (slightly wider, with swollen ends in S. horizontalis ).
