Sinoderces taichi Li & Li sp. nov. Figs 11, 12, 21, 22
Types.
Holotype: ♂, Lingshui Town, Hainan Province, China. 18°43.777'N, 109°51.740'E, 03.IV.2012, Chen Z. leg. Paratypes: 2♀, same data as holotype.
Etymology.
In ventral view (Fig. 11A), the embolus and conductor resemble the yin-yang symbol representing the philosophy behind the Chinese martial art of Taichi; noun in apposition.
Diagnosis.
Sinoderces taichi sp. nov. resembles S. xueae sp. nov. in having a similarly shaped conductor and embolus. However, the males can be distinguished by the following: six spines on the distal part of the palpal cymbium, as against vs. five in S. xueae sp. nov.; a coiled embolus and long conductor. The edge margin of the epigyne is very thick (Fig. 12B).
