Type material: Holotype: male ( IZCAS), Yanhui Cave (Alt.: 1050 m; T.: 16 ºC; H.: 90%), Daxing Village , Liutong Town, Xiuwen County [27°06.413´N, 106°29.561´E, Guizhou, China], 20 April 2007, Y.C.

Etymology. The species is named after the collector, Ms. Xiaomei Su (a Ph. D. candidate in Institute of Zoology, Chinese Academy of Sciences), name in genitive case.

Diagnosis. Leptonetela suae sp. nov. is similar to L. quinquespinata sp. nov., but may be distinguished by the decussated shape of conductor and embolus, the subround pedipalpal bulb, the presence of 5 long setae on pedipalpal tibia prolaterally, the detached spermathecae each other and the larger body size.

Description. Holotype male. Total length 2.42. Prosoma 1.10 long, 1.00 wide. Sternum 0.66 long, 0.57 wide. Opisthosoma 1.30 long, 1.04 wide. Dorsal shield of prosoma yellow, 2 long setae on apex of cephalic area, short setae along antromargin of clypeus. Thoracic median groove fuscous, needle-shaped. Cervical groove and radial furrows indistinct. Clypeus 0.20 high, slightly sloped anteriorly. Eyes absolutely absent. Chelicerae yellow, fang furrow with 8 promarginal and 5 retromarginal teeth. Endites, labium, sternum and legs yellow. Leg measurements: I 10.24 (2.90, 0.43, 3.03, 2.30, 1.58); II 9.05 (2.60, 0.40, 2.60, 2.05, 1.40); III 7.96 (2.35, 0.38, 2.20, 1.85, 1.18); IV 9.31 (2.70, 0.38, 2.65, 2.23, 1.35). Leg formula: I-IV-II-III. Four prolateral setae at femur I mesially. Only one seta at femora II, III and IV respectively. One dorsal seta at patella distally. Three trichobothria and 9–11 setae modified each tibia. Each metatarsus with only one trichobothrium. A finely serrated hairs-comb at ventral base of metatarsi II and III respectively. Opisthosoma pale yellow, ovoid, lacking pigment, covered with long hairs.

Pedipalpal femur with 2 long setae ventrally. One dorsal seta at patella distally. Three dorsal trichobothria, 5 prolateral long setae and 5 retrolateral large spurs modified pedipalpal tibia. Pedipalpal tarsus rugose and contracted mesially, attaching an earlobe-shaped process and 4 distal long setae. Pedipalpal bulb subround, surface smooth. Prolateral lobe tongue-shaped, sclerotized faintly. Embolus and conductor long, sharply triangular, and crossed each other. Median apophysis absent.

Female. Similar to male in general features and somatic coloration, but body size larger and legs shorter. Total length 2.62. Prosoma 1.20 long, 1.10 wide. Sternum 0.74 long, 0.68 wide. Opisthosoma 1.62 long, 1.40 wide. Clypeus 0.22 high. Eyes absent. Chelicerae yellow, fang furrow with 7 promarginal and 5 retromarginal teeth. Endites, labium, sternum and legs yellow. Leg measurements: I 9.78 (2.80, 0.43, 2.90, 2.15, 1.50); II 8.17 (2.05, 0.42, 2.50, 1.90, 1.30); III 7.65 (2.30, 0.40, 2.10, 1.75, 1.10); IV 9.03 (2.65, 0.38, 2.60, 2.10, 1.30). Leg formula: I-IV-II-III. Four prolateral setae at femur I mesially, but 2 at femur II, III and IV respectively. One dorsal long seta on patella distally. Each tibia modified by 3 dorsal trichobothria and 8–10 setae. Only a trichobothrium on each metatarsus. A finely serrated hairs-comb on ventral base of metatarsi II and III respectively. Opisthosoma pale, ovoid, covered with long hairs, lacking pigmentation.

Genital area covered with densely plumose long hairs. Internal genitalia with a pair of curled spermathecae and sperm ducts, weakly sclerotized and spaced. The atrium board, spindle-shaped, procurved antromarginally. Spermathecae, sperm ducts and margin of atrium lacking modified short hairs.
