Etymology. This species is named after Mr. Lu Qiu, the collector of the specimen; noun (name) in genitive case.

Diagnosis. This new species resembles P. hanyikan   sp. nov. by the males having a slender embolus and median apophysis, and the females having similar copulatory openings, copulatory ducts and spermathecae. However, the male of P. qiulu   sp. nov. can be distinguished by the middle of the embolus which is consistently wide, the absence of an apophysis at the embolic base, and the tip of the embolus is anterior to the median apophysis, near the apex of the palp. In the female, the positions of the copulatory openings are posterior to the secondary spermathecae, primary spermathecae oval, width of copulatory ducts equal to that of primary spermathecae.

Description. Male (IZCAS-Ar397013). Total length 5.64, carapace 2.40 long, 3.56 wide, opisthosoma 3.56 long, 3.64 wide. Eye sizes and interdistances: AME 0.17, ALE 0.17, PME 0.15, PLE 0.18, AME–AME 0.08, AME–ALE 0.07, PME– PME 0.19, PME–PLE 0.24, AME–PME 0.07, ALE–PLE 0.18. Clypeus height 0.03. Chelicerae with four promarginal and three retromarginal teeth. Leg measurements: leg I: 8.10 (2.94 + 2.75 + 1.47 + 0.94), leg II: 12.39 (4.08 + 4.55 + 2.53 + 1.23), leg III: 11.77 (3.96 + 4.20 + 2.43 + 1.18), leg IV: 9.74 (3.52 + 3.16 + 2.05 + 1.01). Leg formula: 2341.

Male palp ( Figs 5 View Figure 5 C–D, 8D). Retrolateral tibial apophysis absent. Cymbium oval, sub-tegulum red-brown, mostly hidden under tegulum. Tegulumnearly oval, median apophysis thin, worm-shaped. Embolus slightly curved, worm-shaped, the middle of embolus is expanded, embolic base apophysis absent. Conductor membranous and surrounds half of the embolus, originating between median apophysis and embolic base.

Female (IZCAS-Ar39715). Total length 9.36, carapace 2.84 long, 4.55 wide, opisthosoma 6.47 long, 6.09 wide. Eye sizes and interdistances: AME 0.17, ALE 0.13, PME 0.14, PLE 0.23, AME–AME 0.13, AME–ALE 0.16, PME–PME 0.31, PME–PLE 0.31, AME–PME 0.12, ALE–PLE 0.23. Clypeus height 0.05. Chelicerae with five or six promarginal and three retromarginal teeth. Leg measurements: Leg I: 9.94 (3.56 + 3.32 + 1.92 + 1.14), leg II: 12.45 (4.95 + 4.97 + 1.29 + 1.24), leg III: 14.12 (4.90 + 5.05 + 2.91 + 1.26), leg IV: 11.64 (4.30 + 3.68 + 2.53 + 1.13). Leg formula: 3241.

Epigyne ( Figs 5 View Figure 5 A–B) copulatory ducts curved, semicircular. Secondary spermathecae anterior to copulatory openings, small, size equal to secondary spermathecal head. Primary spermathecae oval, posterior to secondary spermathecae, connected with fertilization ducts.
