description: <i>Leptonetela hamata</i> sp. nov. Figs 22–23, 61 <b>Type material:</b> <b>Holotype</b>: male (IZCAS), Dayu Cave (Alt.: 1270 m; T.: 15 ºC; H.: 92%), Hongfenghu Lake, Hongfenghu Town, Qingzhen City [26°28.384´N, 106°25.542´E, Guizhou, China], 21 April 2007, Y.C. Lin and J. Liu leg. <b>Paratypes</b>: 7 males and 46 females, same data as holotype (IZCAS). <b>Other material examined.</b> <b>CHINA: Guizhou:</b> 2 females, Guanyin Cave (Alt.: 1253 m; T.: 15 ºC; H.: 90%), Jiangjun Bay, Hongfenghu Lake, Hongfenghu Town, Qingzhen City [26°28.184´N, 106°25.527´E], 21 April 2007, Y.C. Lin and J. Liu leg. (IZCAS). <b>Etymology.</b> The specific name of new species is derives from the Latin word “ <i>hamatus</i> ” (= like a hook), in reference to the shape of median apophysis on the male pedipalpal bulb. Gender is feminine. <b>Diagnosis.</b> <i>Leptonetela hamata</i> <b>sp. nov.</b> differs from the other congeners by the presence of a hookshaped median apophysis, the subequal length of tibial spurs I–III, the spur II crossed with spine III on tibia retrolaterally, the presence of two plumose long spines on pedipalpal tarsus and the rugose genital atrium. <b>Description.</b> Holotype male. Total length 1.42. Prosoma 0.68 long, 0.66 wide. Sternum 0.56 long, 0.53 wide. Opisthosoma 0.84 long, 0.58 wide. Dorsal shield of prosoma yellow, with two pair of long setae, one anear ocular area and other on thoracic center. Thoracic median groove fuscous, needle-shaped. Cervical groove and radial furrows distinct, pale brown. Clypeus 0.16 high, slightly sloped anteriorly. Extreme degradation of the eyes, only few vestige. Chelicerae shorter slightly than endites, pale brown, fang furrow with 8 pronarginal and 4 retromarginal teeth. Endites yellow, labium pale yellow and reborder. Sternum and legs yellow. Leg measurements: I 4.98 (1.45, 0.25, 1.56, 1.13, 0.59); II 4.13 (1.20, 0.26, 1.14, 0.92, 0.61); III 3.48 (0.97, 0.24, 0.92, 0.83, 0.52); IV 4.70 (1.35, 0.24, 1.42, 1.08, 0.61). Leg formula: I-IV-II-III. Some thick spines in the middle of femur I prolaterally. Tibiae I and II retrolaterally bear a row of thin hairs respectively. A finely serrated hairs-comb on ventral base of metatarsi II and III severally. Opisthosoma pale, ovoid, covered with sparse long hairs, lacking modified speckles. Pedipalpal femur covered with long hairs, spineless. Patella short, with a distally dorsal spine. Four trichobothria and 5 large spurs modified pedipalpal tibia. Tibial spurs I, II and III subequal in sizes. Tarsus rugose at one third of aparted from tarsal base, earlobe-shaped process small, 4 long and 2 plumose spines modified tarsus distally. Pedipalpal bulb smooth, nearly egg-shaped, embolus and conductor broad, translucent. Median apophysis curved, hook-shaped, sclerotized weakly. Female. Similar to male in general features and body size, but legs shorter. Total length 1.65. Prosoma 0.65 long, 0.63 wide. Sternum 0.57 long, 0.54 wide. Opisthosoma 1.00 long, 0.82 wide. Reduced tiny eyespots white. Clypeus 0.18 high, slightly sloped anteriorly. Leg measurements: I 4.53 (1.28, 0.23, 1.32, 1.02, 0.68); II 3.58 (1.02, 0.23, 1.00, 0.79, 0.54); III 3.06 (0.86, 0.22, 0.77, 0.72, 0.49); IV 4.24 (1.20, 0.22, 1.26, 0.97, 0.59). The chaetotaxy of legs same as in male. Genital area covered with plumose long hairs. Internal genitalia with a pair of spermathecae and sperm ducts, kinkled and sclerotized, fuzz modified on sperm ducts. Atrium broad, rugose. <b>Distribution.</b> Known only from type locality.
