Allotrochosina huangi Wang, Li & Zhang , sp. nov. ( Figs 1A–B , 3A–I , 4A–D, 5A–E)

Type material. Holotype ♂, Ledong County, Jianfengling Nature Reserve , Mingfeng Valley, 18°44.485′N, 108°50.812′E, elev. 960 m, 28.III.2015, L.Y. Wang & G.Q. Huang leg. ( SWUC) . Paratypes. 9♂ 13♀, same data as holotype ( SWUC) ; 2♂ 4♀, Jianfengling Nature Reserve , Wufengqu, 18°44.415′N, 108°51.802′E, elev. 900 m, 18 May 2011, Y.Y. Zhou leg. ( IZCAS) .

Etymology. The specific name comes from the family name of the collector, Guiqiang Huang; noun (name) in genitive case.

Diagnosis. The new species resembles A. schauinslandi (Simon, 1899) ( Vink, 2002: 18, figs 7, 34, 41, 68, 95; Framenau, 2008: 467, fig. 7) but differs by the crescent-shaped embolus ( Figs 3C–G , 4A–D, 5A–C); the embolus is needle-shaped, and the embolic division has a small beak-shaped projection in A. schauinslandi . Females can be differentiated by the shape and orientation of the spermathecae ( Figs 3H–I , 5D–E).
