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).

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.
