Li & Lin sp. nov. Figures 17 , 18 , 23 Type material. Holotype ♂ (IZCAS-Ar 41048) and paratypes 2♀ (IZCAS-Ar 41049, 41050) China : Guangxi Zhuang Autonomous Region, Guilin City, Yangshuo County, Xinping Township, Bingshiyan Cave ( 24.94477°N , 110.60615°E ), 11.I.2013, J. Du and X. Wang leg.; 1♂ juvenile (NHMSU-HA018) and 1♀ (NHMSU-HA018) used for sequencing, GenBank: MW970236 and MW970235, same data as for preceding. Etymology. The specific epithet derives from the name of the type locality; noun in apposition. Diagnosis. See diagnosis for K. maguai sp. nov. Description. Male (IZCAS-Ar 41048). Total length 0.60. Carapace 0.28 long, 0.24 wide, 0.36 high. Clypeus 0.20 high. Sternum 0.16 long, 0.16 wide. Abdomen 0.28 long, 0.28 wide, 0.48 high. Length of legs: I 1.04 (0.30, 0.12, 0.24, 0.14, 0.24); II 0.86 (0.24, 0.12, 0.20, 0.10, 0.20); III 0.66 (0.16, 0.10, 0.12, 0.10, 0.18); IV 0.82 (0.26, 0.10, 0.16, 0.14, 0.16). Somatic characters (Fig. 17A-C and G-I ). Colouration : body dark, nearly black. Legs light brown, with black pigmentation. Prosoma : carapace longer and higher than wide. Cephalic apex at PME position. ALE> PLE = PME, PME separated by ca. half a radius, PER recurved. Clypeus concave, paired notches separated by more than width of PME (Fig. 17G and H ). Labium short, with shallow notch. Legs : each patella with 1 long dorsal seta, each tibia with 2 long dorsal setae. Opisthosoma : shape as in K. maiguai sp. nov., spinnerets dark. Figure 17.

A male habitus, dorsal B male habitus, ventral C male habitus, lateral D female habitus, dorsal E female habitus, ventral F female habitus, lateral G male prosoma, anterior H male prosoma, lateral I male chelicerae, anterior. Abbreviation: TS = male clasping spines on tibia II. Scale bars: 0.50 ( A-F ); 0.20 ( G, H ); 0.10 ( I ). Palp (Fig. 18A and B ): strongly sclerotised. Proximal cymbial process (CP1) small, sharp, needle-like, distal cymbial process (CP2) large, hooked. Cymbial apophysis (CP) truncated, with 2 distal long setae. Distal bifurcation of median apophysis located directly below the hooked CP2 (Fig. 18A ). Tegulum translucent, weakly rugose, with a triangular apical process. Embolus longer than median apophysis, robust, horn-like, strongly sclerotised, gradually tapering, bent at nearly proximal ⅓, forked at terminus. Figure 18. Kirinua yangshuo sp. nov.

Legs : spination of each leg as in male. Opisthosoma : laterally oviform. Spinnerets Located ventrally. Epigyne (Fig. 18C-F ): plate wider than long, strongly sclerotised. Scape wider than long, slightly protruded. Spermathecae globose, separated by more than 3.5 diameters. Copulatory ducts long, their proximal parts enlarged, forming a broad, inverted, subtriangular atrium, with knob-shaped lateral humps; middle part coiled more than 5 times; distal part connected longitudinally to spermatheca. Fertilisation duct slightly bent, runs along lateral wall of atrium, originating above coiled part of copulatory duct. Distribution. China (Guangxi) (Fig. 23 ).
