Holotype: ♂, Ai Cave, Baoyou Village, Qicha Town, Changjiang li autonomous County, Hainan Province, China. 19°6.068'N, 109°1.200'E, 125 m, 18.XII. 2014, Zhao Z. and Shao L. leg. Paratypes: 1♂2♀, same data as holotype.
Etymology.
The specific name refers to the name of the cave; adjective.
Diagnosis.
Sinoderces aiensis sp. nov. can be distinguished from all other known species by the light-colored bulb, a curved conductor with a slightly curved tip ( Fig. 15 View Figure 15 ) and an embolus shaped like the Nike swoosh logo ( Fig. 15B, C View Figure 15 ). There is a finger-like projection at the junction of the tarsus and the tibia. Females may be recognized by the antler-like spermathecae ( Fig. 16A View Figure 16 ).

Male (holotype). Total length 1.31; carapace 0.54 long, 0.50 wide; abdomen 0.77 long, 0.43 wide. Carapace round, light yellow, with darker yellow margins and a narrow, dark yellow median line behind ocular area ( Fig. 16E View Figure 16 ). Clypeus and chelicerae yellow. Cheliceral promargin with one tooth, followed by a lamina, retromargin with one small tooth ( Fig. 21H View Figure 21 ). Endites and labium dark yellow. Sternum yellow. Legs light yellow. Leg measurements: I missing, II missing, III missing, IV 4.14 (1.10, 0.20, 1.20, 1.20, 0.44). Abdomen elongated, gradually darkens from anterior to posterior ( Fig. 16E View Figure 16 ). Spinnerets dark yellow.
Male palp ( Fig. 15 View Figure 15 ): The palp is almost light yellow. Bulb light, ovate; conductor with a slightly curved tip and the embolus like the Nike swoosh logo. Tibia with a stout apical protrusion, the protrusion with many bristles ( Fig. 15B View Figure 15 ). Oval femur with hairs.
