Etymology. The specific name is a noun in apposition taken from the type locality.

Diagnosis. Leptonetela jiulong sp. nov. resembles L. hexacantha sp. nov., but differs from the latter by the presence of 6 tibial spurs on pedipalp retrolaterlly, the tibial spurs I and II contiguous that spur I thickset and spine II bifurcate, the presence of a large seta on earlobe-shaped process of pedipalpal tarsus mesially, the broad and wrinkled conductor.

Description. Holotype male. Total length 1.89. Prosoma 0.81 long, 0.76 wide. Sternum 0.66 long, 0.63 wide. Opisthosoma 1.16 long, 0.79 wide. Dorsal shield of prosoma brown yellow, thoracic median groove brown, needle-shaped, a seta on anterior area of median groove, cervical groove and radial furrows distinct, pale brown. Clypeus 0.22 high. Six eyes, on black bases. A seta on anterior area of ALE, two long setae on anterolateral area of PME. Eye sizes: ALE 0.06, PLE 0.07, PME 0.05; ALE-PME 0.15, PLE-PLE 0.09, PLE- PME 0.07; AER 0.14, PER 0.17. Major axes of PLE convergent. Chelicerae longer than endites, pale brown, fang furrow with 8 promarginal and 5 retromarginal teeth. Endites and labium pale brown. Sternum peltate, brown-yellowish, with dark speckles. Legs yellow. Leg measurements: I 8.93 (2.47, 0.30, 2.73, 2.22, 1.21); II 6.52 (1.87, 0.28, 1.90, 1.48, 0.99); III 5.21 (1.51, 0.21, 1.45, 1.28, 0.76); IV 7.27 (2.08, 0.28, 2.24, 1.75, 0.92). Leg formula: I-IV-II-III. Each femur covered with long setae. Three trichobothria, 3 or 5 setae on each tibia. A row of thin hairs on tibiae I and II retrolaterally. Only one hairs-comb at the base of metatarsus III ventrally. Opisthosoma ovoid, covered with hairs and speckles, pale yellow dorsally, pale ventrally and rugose posteriorly.

Pedipalpal femur spineless. A dorsal spine on patella distally. Tibia modified by 3 dorsal trichobothria, 4 retrolateral large spines and 2 distal spines (tibial spur I thickset and bent, spur II long and bifurcate). Tarsus distinctly rugose and contracted mesially, with 3 large setae distally, attaching an earlobe-shaped process with a long seta. Pedipalpal bulb ovoid and smooth. Prolateral lobe small. Conductor broad and rugose. Median apophysis broad and smooth. Embolus sclerotized weakly, wide basally and narrow distally.

Female. General features similar to male, but body size larger and legs shorter. Total length 2.01. Prosoma 0.84 long, 0.79 wide. Sternum 0.68 long, 0.65 wide. Opisthosoma 1.21 long, 1.03 wide. Clypeus 0.21 high. Six eyes, PME slightly bigger than in male. Eye sizes: ALE 0.06, PLE 0.07, PME 0.06; ALE-PME 0.14, PLE- PLE 0.13, PLE-PME 0.07; AER 0.14, PER 0.16. Leg measurements: I 7.35 (1.95, 0.30, 2.19, 1.75, 1.16); II 5.58 (1.57, 0.26, 1.60, 1.27, 0.88); III 4.62 (1.30, 0.25, 1.23, 1.12, 0.72); IV 6.39 (1.85, 0.26, 1.91, 1.51, 0.86). The chaetotaxy of each leg same as in male.

Genital area covered with long hairs. Internal genitalia consisting of a pair of kinkled spermathecae and sperm ducts, sclerotized distally stronger than proximally. The atrium wide and smooth, spindle-shaped, lacking modified short hairs on anterior margin.
