Etymology. The specific epithet is derived from the type locality; adjective.

Diagnosis. Drapetisca yuelushanensis sp. n. resembles D. socialis in having the similar slightly curved, protruding scape in lateral view ( Figs 65A–D View FIGURE 65 ; Tu & Li 2006, figs 22–25), and can be distinguished by the posterior median plate rectangular in D. yuelushanensis sp. n. ( Figs 65A–D View FIGURE 65 ; vs. somewhat trapezoid).

Description. Female (holotype, Figs 66A, B View FIGURE 66 ): Total length: 2.10. Carapace 0.99 long, 0.73 wide, cephalic region slightly elevated, greenish, fovea, cervical and radial grooves distinct. Clypeus 0.19 high. Chelicerae with five promarginal and three retromarginal teeth. Sternum longer than wide, black with microsetae. Eyes: AER recurved, PER straight. Eye sizes and interdistances: AME 0.04, ALE 0.07, PME 0.07, PLE 0.06, AME–AME 0.03, PME–PME 0.04, AME–ALE, 0.07, PME–PLE 0.05, AME–PME 0.08, ALE–ALE 0.34, PLE–PLE 0.36, ALE– PLE contiguous. Legs with annuli. Length of legs: I 4.53 (1.19, 1.49, 1.11, 0.74), II 3.92 (1.07, 1.21, 0.97, 0.67), III 3.21 (0.94, 0.96, 0.80, 0.51), IV 4.09 (1.14, 1.25, 1.03, 0.67). Tibial spine formula: 2-2-2-2. TmI 0.51 and TmIV present. Opisthosoma 1.11 long, 0.69 wide, oval, dorsally with distinct pattern extending posteriorly and laterally with irregular white patches, ventral side brownish black.

Epigyne ( Figs 65A–D View FIGURE 65 ): Protruding, posteriorly slightly curved, distal end with well-developed lateral pockets (LP); posterior median plate (PMP) rectangular. Spermathecae (S) C-shaped present antero-laterally.

Male. Unknown.

Distribution. Known only from the type locality (Hunan Province, Fig. 315 View FIGURE 315 ).

Comment. Due to the absence of male specimens, it is uncertain whether Drapetisca boletus sp. n. and D. yuelushanensis sp. n. should be classified as separate genera; therefore, they are provisionally assigned to the genus Drapetisca . The female of D. nanpingensis sp. n. bears resemblance to the type species, but its palp is distinctly different; hence, this new species is also provisionally placed within the genus Drapetisca .
