description: <i>Leptoneta setulifera</i> n. sp. (Fig. 4) TYPE MATERIAL. — Holotype: China, Beijing City, Fangshan District, Shidu Town (39°42’N, 115°37’E), Liuhe Village, Beipo Cave, 11.V.2005, leg. Q. Wang, &amp;male; (MNHN). Paratypes: same locality as holotype, 5.IX.2006, leg. S. Li, Y. Lin &amp; J. Liu, 6 &amp;male;&amp;male;, 25 &amp;female;&amp;female; (IZCAS). — Same locality as holotype, 5.IX.2006, leg. S. Li, Y. Lin &amp; J. Liu, 3 &amp;male;&amp;male;, 3 &amp;female;&amp;female; (MNHN). ETYMOLOGY. — The specific name comes from Latin, <i>set</i>, hairs, and combined with suffix <i>fera</i>, bearing, in reference to the hairs presented on carapace. DIAGNOSIS. — The new species is similar to <i>L. handeulgulensis</i> Namkung, 2002 (Namkung 2003), but can be distinguished by the presence of many long spines on ventral surface of male palpal femur, and the presence of hook-like projection on male palpal tibia.

Abdomen haired, brown on dorsum and dark brown on lateral and ventral surfaces, and oval in shape, dorsum with black brown transverse stripes posteriorly, forming three to four folds. Palpal femur with many spines ventrally. Palpal tibia with three long trichobothria on the dorsal surface and with a single hook-like projection disto-laterally (Fig. 4 A-C).
