Figs 7 , 8 Type material. Holotype ♀ ( IZCAS ), China : Taiwan, Nantou County, Ren'ai Township, Songgang Village, 24°05.222'N , 121°10.335'E , 2067 m, 2.VII.2013, G. Zheng leg. Etymology. The new species is named after the type locality; noun in apposition. Diagnosis. Chimena nantou sp. nov. shares a similar configuration of the vulva to C. qiong sp. nov. and C. taiwanica comb. nov., but differs from the former by the shorter spermathecae with fewer spirals (longer and with more spirals in C. qiong ) (cf. Fig. 7E, F vs. Fig. 4I, J ), and from the latter by the more compact spermathecae (elongated in the latter) (cf. Fig. 7E, F vs. Fig. 6I, J ). Figure 7. Chimena nantou sp. nov., holotype female A habitus, dorsal B habitus, ventral C habitus, lateral D epigyne, ventral E vulva, ventral F vulva, dorsal. Abbreviations: CD copulatory ducts; FD fertilization ducts; S spermathecae; SP scape. Scale bars: 0.50 mm ( A-C ); 0.10 mm ( D-F ). Description. Female : Habitus as in Fig. 7A-C . Total length 0.75. Carapace 0.25 long, 0.23 wide. Clypeus 0.07 high. Sternum 0.24 long, 0.22 wide. Abdomen 0.45 long, 0.42 wide. Length of legs: I 0.98 (0.30, 0.13, 0.19, 0.14, 0.22); II 0.87 (0.27, 0.12, 0.17, 0.14, 0.18); III 0.66 (0.19, 0.09, 0.14, 0.14, 0.16); IV 0.80 (0.23, 0.10, 0.16, 0.15, 0.18). Somatic features as in female of C. taiwanica comb. nov. Epigyne (Fig. 7D-F ): vulval configuration similar to C. qiong sp. nov. and C. taiwanica comb. nov. Genital area bears sparse setae, without a dark speckle. Spermathecae short, tapering at distal end and proximal base, separated by ca 1.1 x their length. Scape knob shaped, rugose, membranous. Copulatory ducts translucent. Most of fertilization ducts intertwined with spermathecae, distal part of fertilization ducts thin, inflected. Male. Unknown. Distribution. China (Taiwan) (Fig. 8 ).
