Li & Lin sp. nov. Figures 5 , 23 Type material. Holotype ♀ (IZCAS-Ar 41038) China : Guangxi Zhuang Autonomous Region, Hechi City, Fengshan County, Jiangzhou Township, underground gallery (a limestone cave) ( 24.33144°N , 106.98716°E ; 449 m alt.), 25.III.2015, Y. Li and Z. Chen leg.; 1♀ (NHMSU-HA012) used for sequencing, GenBank: MW970234, same data as preceding. Etymology. The specific epithet derives from the name of the type locality; noun in apposition. Diagnosis. This new species is similar to P. putao sp. nov. and P. woodwardi in the configuration of the vulva, but it differs by the smaller spermathecae that are separated by their width, the shorter copulatory ducts and the larger, trumpet-shaped copulatory openings (Fig. 5D and F-G ) vs. the larger, adjacent spermathecae, the longer copulatory ducts and the smaller, circular copulatory openings (cf. Fig. 11D and F-G and fig. 123 in Forster 1959 ). Figure 5. Patu jiangzhou sp. nov. A female habitus, dorsal B female habitus, ventral C female habitus, lateral D epigyne, ventral E epigyne, lateral F vulva, ventral G vulva, dorsal. Abbreviations: CD = copulatory ducts; CO = copulatory opening; FD = fertilisation ducts; Pl = parmula; S = spermathecae. Scale bars: 0.50 ( A-C ); 0.10 ( D-G ). Description. Female (IZCAS-Ar 41038). Total length 0.60. Carapace 0.24 long, 0.24 wide, 0.24 high. Clypeus 0.10 high. Sternum 0.16 long, 0.16 wide. Abdomen 0.44 long, 0.44 wide, 0.44 high. Length of legs: I 0.80 (0.24, 0.12, 0.16, 0.12, 0.16); II 0.74 (0.22, 0.12, 0.14, 0.10, 0.16); III 0.60 (0.14, 0.10, 0.12, 0.10, 0.14); IV 0.76 (0.22, 0.10, 0.16, 0.12, 0.16). Somatic characters (Fig. 5A-C ). Colouration : carapace yellow. Mouthparts light brown. Sternum pale yellow. Legs light brown, tibia, metatarsi and tarsi dark grey. Abdomen pale. Spinnerets light brown. Prosoma : carapace smooth, as long as wide and high, dorsally pear-shaped. Cephalic part moderately raised. ALE> PME> PLE. PER straight, lateral eyes adjacent, PME contiguous. Chelicerae stubby, with sparse, short setae anteriorly. Endites nearly quadrilateral. Labium rectangular, wider than long. Sternum faintly plump, smooth, with sparse setae. Legs : 1 long disto-dorsal seta on all patella; tibia I and II with 3 dorsal setae and 1 on tibia III and IV; dense, thin setae on tibia, metatarsi and tarsi. Opisthosoma : almost globose, cuticle modified by sparse, long setae and faintly ossified dots. Spinnerets brown, anterior spinnerets more fuscous than posterior spinnerets. Epigyne (Fig. 5D-G ): distinctly sclerotised, internal structures faintly visible via the cuticle. Parmula tongue-shaped, wider than long, slightly protruded. Copulatory openings trumpet-shaped, located at basal side of parmula bilaterally. Spermathecae small, ovoid, separated by ca. 1.5 x their diameter. Copulatory ducts long, twisted four times before connecting with the anterior margin of spermathecae. Fertilisation ducts shorter and thinner than copulatory ducts, originate at posterolateral margin of spermathecae, slightly bent and extended downwards, parallel to proximal part of copulatory ducts. Male. Unknown. Distribution. China (Guangxi) (Fig. 23 ).
