Material examined.

Holotype: ♀, China, Jiangxi Province, Ji’an City, Jinggangshan County Level City , Jinggang Mountain National Nature Reserve , Ciping Town , Dajing Village , Lingxiufeng Scenic Spot , 26°34'16.72"N, 114°07'00.56"E, 971 m, 1.X.2018, K. Liu et al. leg.

Etymology.

The specific name is derived from the type locality, Lingxiufeng Scenic Spot; adjective.

Diagnosis.

The female of P. lingxiufengica is similar to that of P. tangi Wang, Mi & Peng, 2016 in having well-developed transverse ridge of copulatory openings (TrR) (= atrial intermediate margin of Wang et al. 2016) and invisible copulatory openings (CO). The new species can be easily differentiated from P. tangi by the convex transverse ridge of copulatory openings (vs. concave) (cf. Fig. 11C and Wang et al. 2016: fig. 2C).

Description.

Habitus as in Fig. 11A, B . Total length 3.08. Carapace: 3.67 long, 3.33 wide. Eye sizes and interdistances: AME 0.05, ALE 0.15, PME 0.10, PLE 0.14, AME-AME 0.07, AME-ALE 0.04, PME-PME 0.12, PME-PLE 0.13, AME-PME 0.22, AME-PLE 0.31, ALE-ALE 0.25, PLE-PLE 0.57, ALE-PLE 0.14. MOA 0.35 long, front width 0.18, back width 0.32. Chelicerae with three promarginal (proximal largest, distal smallest) and three retromarginal (middle and distal with a same base, distal largest, middle smallest) teeth. Endites slightly longer than wide, anterior part broad. Labium slightly wider than long. Sternum (Fig. 11B ) with numerous setae, anteromedially procurved, with subtriangular posterior end. Abdomen (Fig. 11A, B ): 1.69 long, 1.63 wide, with sparse, erected setae. Leg measurements: I 4.28 (1.35, 0.51, 1.22, 0.87, 0.33); II 4.09 (1.23, 0.48, 1.18, 0.80, 0.40); III 2.31 (0.73, 0.36, 0.59, 0.38, 0.25); IV 2.71 (0.93, 0.33, 0.64, 0.55, 0.26). Leg spination: I Fe: d4, p2; Pa: d2; Ti: d2, v10; Mt: v8; II Fe: d1; Pa: d2; Ti: d2, v10; Mt: v8; III Fe: d3; Pa: d1; Ti: d2, p2, v2; Mt: d2, v2; IV: Fe: d1; Pa: d1, r1; Ti: d3, p1, r1; Mt: d2.

Colouration (Fig. 11A, B ). Carapace yellow-brown, medially with single broad, dark brown, mottled band. Legs yellow, basis of macrosetae on legs appearing as darkish brown dots. Chelicerae, endites, sternum, legs, and abdomen reddish yellow. Abdomen with sparse white guanine spots, medially with clear inverted T-shaped dark brown marking; macrosetal bases reddish brown; venter with pairs of longitudinal, short, guanine stripes.

Epigyne (Fig. 11C, D ). Epigyne oval, 1.5 × wider than long, lacking hood. Copulatory openings (CO) invisible, hidden by transverse ridge of copulatory openings (TrR). Copulatory ducts (CD) not visible, possibly absent. Spermathecae (SP) oval, ~ 1.4 × longer than wide, anterior part of spermathecae slightly separated, posterior parts touching. Fertilisation ducts (FD) as long as width of spermatheca, directed laterally.

Male. unknown.

Comments.

There is only one species in the region known from the male only, P. koponeni Benjamin, 2014 (Thailand); however, it is unlikely to be conspecific with our female because of differences in colouration, and the long distance between type localities.

Distribution.

Known only from the type locality in Jiangxi Province of China (Fig. 17 ).
