Zoica hainan Wang, Li & Zhang , sp. nov. ( Figs 72A–H , 73A–D, 74A–D)

Type material. Holotype ♂, Haikou City , Dongzhaigang Mangrove Nature Reserve, 19°57.113′N, 110°33.983′E, elev. - 2 m, 20.VIII.2007, C.X. Wang leg. ( IZCAS) ; Paratypes (7♂ 8♀). 4♂ 4♀, same data as holotype ( IZCAS) ; 1♂ 3♀, Haikou City , Dongzhaigang Mangrove Nature Reserve, 19°57.113′N, 110°33.983′E, elev. - 2 m, 20.VIII.2007, S. Li leg. ( IZCAS) ; 2♂ 1♀, Ding’an County, Tongren Village , 19°30.953′N, 110°18.904′E, elev. 58 m, 27. VI .2019, L.Y. Wang, T . Yuan, K. Yu & J.X. Zhao leg. ( SWUC) .

Etymology. The specific epithet refers to the type locality; noun in apposition.

Diagnosis. The new species resembles Z. unciformis Li, Wang & Zhang, 2013 (Li, Wang & Zhang, 2013: 30, figs 5A– E, 6A–H) but differs by the lateral apophysis with two small projections, the inner projection spinelike, the outer projection longer than wide with a sharp tip ( Figs 72C–F , 73A–D, 74A–B); in Z. unciformis , the lateral apophysis is sinuous, slightly curved, with a small outgrowth. Terminal apophysis covers embolus in the new species ( Figs 72C–F , 73A–D, 74A–B) but not in Z. unciformis . Spermathecae round in the new species ( Figs 72G–H , 74C–D) but oval in Z. unciformis .
