Type material. Holotype: male, China: Chongqing Municipality, Jinyun Mountain, 29°50ʹ30.5ʺN, 106°21ʹ31.1ʺE, Guankou, 28 April 2010, Z.X. Li, K.Y. Xu & L.Y. Wang leg. (SWUC). Paratypes: 1 male and 3 females, same data as holotype (SWUC); 4 males and 11 females, Guankou, 5 April 2010, Z.S. Zhang, Z.X. Li, K.Y. Xu & L.Y. Wang leg. (SWUC); 3 females, Jinyun Mountain, Baizigou, 16–17 April 2010, Z.S. Zhang & Z.X. Li leg. (SWUC); 1 female, Jinyun Mountain, Jinyun Temple, 26 April 2008, Z.S. Zhang leg. (SWUC).
Etymology. The specific name refers to its similarity to L. humulis; adjective.
Diagnosis. The new species is similar to L. humilis and L. nielseni, but distinguished by the long terminal part of conductor, the blunt patellar apophysis; the short, one-loop copulatory ducts and the small spermathecae (Figs 9A–E, 10F–H, 11G–H). The new species also differes from L. nielseni by the presence of white spots on the dorsum of opisthosoma.
