Types.
Holotype: ♂, Limu Mountain Town, Hainan Province, China. 19°12.002'N, 109°43.710'E, 591 m, 25.III.2012, Chen Z. leg. Paratype: 1♀, same data as holotype.
Etymology.
This name is in honor of Wenjing Xue, a good friend of the first author of the paper who has been helpful to his study and life. The case is feminine and genitive.
Diagnosis.
Sinoderces xueae sp. nov. resembles S. taichi sp. nov. in having a similarly shaped conductor and embolus. However, the males can be distinguished by the following: five spines on the distal part of the palpal cymbium, vs. six in S. taichi sp. nov; the slightly sigmoid embolus and short conductor ( Fig. 9 View Figure 9 ) vs. a coiled embolus and long conductor in S. taichi sp. nov. The margin of the epigyne of S. xueae sp. nov. is thin ( Fig. 10B View Figure 10 ) whereas in S. taichi sp. nov. thick ( Fig. 12B View Figure 12 ).
