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
).

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 (
