Allotrochosina limu Wang, Li & Zhang , sp. nov. ( Figs 6A–C , 7A–B)

Type material. Holotype ♂, Qiongzhong County, Limu Mountain Nature Reserve , Zhufeng, 19°10.874′N, 109°45.322′E, elev. 940 m, 4.V.2011, Y.Y. Zhou leg. ( IZCAS).

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

Diagnosis. The new species resembles A. huangi Wang, Li & Zhang , sp. nov. ( Figs 3C–G , 4A–D, 5A–C) but differs by the heart-shaped median apophysis ( Figs 6B–C , 7A–B,); the median apophysis is liver-shaped in A. huangi ( Figs 3C–F , 4A–B, D, 5A–C,). Embolus rodlike, pointed at the end in the new species ( Figs 6B–C , 7A–B), crescent-shaped in A. huangi ( Figs 3C–G , 4A–C, 5A–B). In retrolateral view, the terminal apophysis is horn-shaped in the new species ( Figs 6B–C , 7A– B) but hook-shaped in A. huangi ( Figs 3C–G , 4A–C, 5A–C).
