Type material. Holotype ♂ (IZCAS-Ar39291): Zibo National Forest Park (N33.669430°, E106.825930°, 1352 m), Liuhou Township , Liuba County, Hanzhong City, Shaanxi Province, China, 24. X. 2013, Y. Li and J. Liu leg. Paratype: 1♀ (IZCAS-Ar39292): same locality as holotype, 12. XI. 2013, H. Zhao leg.

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

Diagnosis. Males are most similar to those of other Lineacoelotes species but can be distinguished from congeners by the tip of patellar apophysis bifurcated ( Fig. 6C , arrow). Females can be easily distinguished from other Lineacoelotes species by the epigynal teeth converging and extending over the posterior margin of the large atrium, the anterior margin of the atrium sunken medially, and the fovea with a septum ( Fig. 7A ).

Description. Male (holotype). Carapace light yellow-brown, same colour as clypeus; endites, labium and sternum the same colour as carapace, legs lighter than carapace; femur surrounded by two grey rings of hair. Abdomen grey-brown, dorsal view of abdomen with four chevron-shaped patterns, spinnerets and abdomen similar in colour and slightly yellowish brown. Total length 5.68. Carapace 2.65 long, 2.15 wide. Abdomen 3.03 long, 1.74 wide. Eye sizes and interdistances: AME 0.11, ALE 0.17, PME 0.16, PLE 0.19; AME-AME 0.05, AME-ALE 0.04, AME- PME 0.07, ALE-PLE 0, PME-PME 0.08, PME-PLE 0.08. Leg measurements: I 14.17 (3.61, 4.59, 3.56, 2.41); II 12.44 (3.36, 3.69, 3.06, 2.33); III 11.76 (2.98, 3.56, 3.24, 1.98); IV 15.32 (3.87, 4.56, 4.42, 2.47). Chelicera with 3 promarginal and 2 retromarginal teeth. Palp: femur 3.4 times longer than wide; patella longer than wide; tibia 1.7 times longer than wide; patellar seta longer than patella; patellar apophysis wide and long, about 3 times thinner than tibia, length about 2/3 the length of the tibia, with flat tip; retrolateral tibial apophysis extending to the anterior margin of the tibia, width narrower than the width of the patellar apophysis, with blunt tip; cymbial furrow about 2/3 the width of the cymbium and about 1/2 the length of the cymbium; embolus beginning at 5:30 o’clock position, long and distorted; conductor with two small apophyses (C2 and C3), a broad groove, and a lamella; median apophysis spoon-shaped ( Fig. 6 A–C).

Female (IZCAS -Ar39292). Carapace dark brown-yellow, spinnerets slightly grey, otherwise the same as males. Total length 6.43. Carapace 2.86 long, 1.93 wide. Abdomen 3.58 long, 2.07 wide. Eye sizes and interdistances: AME 0.11, ALE 0.18, PME 0.13, PLE 0.16; AME-AME 0.06, AME-ALE 0.03, AME-PME 0.10, ALE-PLE 0, PME-PME 0.08, PME-PLE 0.12. Leg measurements: I 10.73 (3.77, 3.18, 2.27, 1.51); II 9.82 (3.63, 2.76, 1.98, 1.45); III 8.92 (3.25, 2.53, 1.95, 1.19); IV 11.93 (3.81, 3.62, 3.01, 1.49). Chelicera with 3 promarginal and 2 retromarginal teeth. Epigyne: plate 1.4 times wider than high; epigynal teeth curved and with blunt tips, extending over posterior margin of the atrium, over 4 times longer than wide, separated from each other by 3 to 5 times their width; atrium large and situated at the central part of plate, the anterior margin sunken medially, the lateral and posterior margins and median septum conspicuous; copulatory ducts large and originating from the anterior margin of the atrium; spermathecae length longer than width, separated from each other by two times their width; spermathecal heads originating from the anterior part of the spermatheca, coiled and extending laterally to the spermathecae; fertilization duct pointing to the bottom, hook-shaped at the tips ( Fig. 7 A–B).

Variation. Carapace length 2.65–2.86.

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