description: <i>SOLENYSA RETRACTILIS</i> TU SP. NOV. (FIGS 10, 18, 19) <i>Types:</i> Male holotype, CHINA: Longmen Cave, altitude 1007 m, Lushan County (30.30°N, 103.20°E), Sichuan Province, coll. Shuqiang Li, 16.x.2005 (IZCAS). Four male and three female paratypes, same data as holotype (IZCAS). <i>Additional material examined:</i> CHINA: Longdong Town, Baoxing County (30.30°N, 102.80°E), Sichuan Province, coll. Lihong Tu &amp; Shuqiang Li, 28.vi.2004, seven males and 16 females (IZCAS); CHINA: Fengtongzhai, Baoxing County (30.30°N, 102.80°E), Sichuan Province, coll. Lihong Tu &amp; Shuqiang Li, 2.vii.2004, two males and three females (IZCAS); CHINA: Mt. Erlangshan National Forest Park, Tianquan County (30.10°N, 102.70°E), Sichuan Province, coll. Lihong Tu &amp; Shuqiang Li, 8.vii.2004, one female (IZCAS). <i>Etymology:</i> The name comes from the Latin <i>retractilis</i> (dragging backwards) in reference to the backwards dragged second branch of the lamella characteristica. <i>Diagnosis:</i> The male of <i>S. retractilis</i> sp. nov. can be distinguished from <i>S. wulingensis</i> and <i>S. geumoensis</i> by the additional sclerotic extension furnished with many teeth at the basal part of anterior terminal apophysis and by the hook-like median terminal apophysis (Fig. 19E, H). The shape of epigynum is diagnostic, being shorter in <i>S. geumoensis</i> (Fig. 18D), more rounded in <i>S. retractilis</i> and <i>S. wulingensis</i>, but the latter two species are difficult to distinguish morphologically (Figs 18D, 21G). <i>Description:</i> Male. Total length 1.43. Carapace 0.83 long, 0.50 wide. Abdomen 0.60 long, 0.42 wide. Chelicerae with four promarginal and two retromarginal teeth. Length of legs: I 2.83 (0.80 + 0.90 + 0.63 + 0.50); II 2.40 (0.67 + 0.77 + 0.53 + 0.43); III 1.84 (0.57 + 0.47 + 0.43 + 0.37); IV 2.44 (0.70 + 0.77 + 0.50 + 0.47). Tm I 0.19, Tm IV absent. Other somatic characters as reported in the genus description. Female. Total length 1.70. Carapace 0.90 long, 0.50 wide. Abdomen 0.97 long, 0.60 wide. Chelicerae with four promarginal and two retromarginal teeth. Length of legs: I 2.90 (0.80 + 0.93 + 0.67 + 0.57); II 2.53 (0.73 + 0.80 + 0.57 + 0.43); III 2.00 (0.57 + 0.60 + 0.43 + 0.40); IV 2.33 (0.73 + 0.637 + 0.50 + 0.47). Tm I 0.21, Tm IV absent. Other somatic characters as in male. Epigynum as in Figure 13E–G. Other genitalic characters as reported in the description of the <i>S. wulingensis</i> group. <i>Variation:</i> Male carapace length is 0.73–0.83, total length 1.33–1.53 (<i>N</i> = 5). Female carapace length is 0.80–0.83, total length 1.53–1.57 (<i>N</i> = 5). <i>Natural history:</i> Specimens of <i>S. retractilis</i> can be found amongst grasses, near the soil surface. <i>Distribution:</i> China (Sichuan) (Fig. 22).
