Type material. Holotype ♀ (IZCAS-Ar39285): Tiantai National Forest Park (N33.249180°, E107.054280°, 1074 m), Wuxiang Township , Hantai District, Hanzhong City, Shaanxi Province, China, 25. X. 2013, Y. Li and J. Liu leg. Paratypes: 2♀ (IZCAS-Ar39286 - Ar39287): same data as holotype .

Etymology. The specific name referring to the type locality: Tiantai National Forest Park.

Diagnosis. Females of L. tiantaiensis sp. n. are similar to those of L. funiushanensis . They can be distinguished from the latter species by the atrium thin and long, and epigynal teeth long ( Fig. 3A ) vs. atrium wide and short, and epigynal teeth short in L. funiushanensis (fig. 5 in Xu et al., 2008).

Description. Female (holotype). Carapace and clypeus brown-yellow, endites and labium dark brown, sternum brown-yellow, the colour of legs lighter than that of carapace, with a grey ring of hair, femur surrounded by two ring hair, patella surrounded by one ring of hair, tibia surrounded by one ring of hair. Abdomen blue-brown, dorsal view of abdomen with five chevron-shaped patterns; the colour of spinnerets and abdomen are the same. Total length 7.04. Carapace 3.40 long, 2.66 wide. Abdomen 3.64 long, 2.38 wide. Eye sizes and interdistances: AME 0.12, ALE 0.19, PME 0.16, PLE 0.18; AME-AME 0.06, AME-ALE 0.07, AME-PME 0.09, ALE-PLE 0, PME-PME 0.11, PME-PLE 0.15. Leg measurements: I 11.62 (3.37, 3.84, 2.74, 1.67); II 10.19 (3.01, 3.43, 2.12, 1.63); III 9.76 (3.07, 3.08, 2.44, 1.17); IV 12.54 (3.37, 3.92, 3.43, 1.82). Chelicera with 3 promarginal and 2 retromarginal teeth. Epigyne: plate 1.3 times wider than high; epigynal teeth long and wide, bent at tips; originating from anterior margin of the atrium and extending over its posterior margin, about 1/2 the height of plate, with 2.8 times longer than wide; the distance between the base of the tooth is shorter than the distance between the tip of the tooth (2.5 times of their width); epigynal atrium situated at the central part of the plate, longer than wide, with their posterior part more sclerotized than other parts of the plate; copulatory ducts large; spermathecae oval, separated from each other; spermathecal heads long, originating from the middle part of the spermathecae; fertilization duct pointing to the front, hook-shaped at the tips ( Fig. 3 A–B).

Male. Unknown.

Variation. Total length of females 6.09–8.33. Carapace length 2.36–2.82.

Distribution. Known only from Shaanxi Province, China ( Fig. 8 ).
