Sinartoria zhuangius sp. nov.

Figs 3–4 , 11

Type material. Holotype ♂ (SWUC-T-LY-07-01), China, Guangxi Zhuang Autonomous Region, Daming Mountain Nature Reserve, Luoyuewang Temple , 23°28.733′N, 108°26.133′E, 1376 m, 24.V.2011, Y.N. Wang & Y.Q. Peng leg.

Etymology. The specific epithet is an adjective latinising the name of the Zhuang ethnic minorities, which inhabit the area where the holotype was found.

Diagnosis. Male of Sinartoria zhuangius sp. nov. resembles S. damingshanensis sp. nov. ( Figs 1A–C , 2D–H ), but can be distinguished from the latter by the following characters. Median apophysis with three small arms and without teeth ( Figs 3A , 4E ), whereas it has relatively long arms and small teeth in S. damingshanensis sp. nov. ( Figs 1A , 2D, F ). Terminal apophysis 2 villus-shaped ( Figs 3 , 4D–E ), whereas it is flame-shaped, slightly curved in S. damingshanensis sp. nov. ( Figs 1A–C , 2D–H ).

Description. Male holotype ( Figs 4A–C ). Total length 4.03. Carapace 2.22 long, 1.59 wide; opisthosoma 1.83 long, 1.13 wide. Eye sizes and interdistances: AME 0.07, ALE 0.07, PME 0.32, PLE 0.22; AME–AME 0.08, AME– ALE 0.09, PME–PME 0.23, PME–PLE 0.28. Clypeus 0.09 high. Leg measurements: I 6.55 (1.71, 2.23, 1.66, 0.95); II 6.12 (1.69, 2.05, 1.50, 0.88); III 5.96 (1.60, 1.88, 1.60, 0.88); IV 8.09 (2.02, 2.62, 2.33, 1.12).

Pedipalp ( Figs 3A–B , 4D–E ). Median apophysis with three arms. Embolus long, slender and resting in a very large and complex terminal apophysis grooved along all its length.

Female. Unknown.

Distribution. Known only from the type locality, Daming Mountain Nature Reserve ( Fig. 11 ).
