Type material. Holotype ♂ (IZCAS-Ar39282): Wuma Village (N30.040500°, E106.572630°, 799 m), Jindaoxia Township , Beibei District, Chongqing Municipality, China, 30.IV. 2014, Y. Lin, H. Zhao, Y. Li, J. Wu and F. Li leg. Paratypes: 1♂ 1♀ (IZCAS-Ar39283-Ar39284): same data as holotype .

Etymology. The specific name is a paronym for Fengyuan Li, one of the collectors of the new species, to commemorate her contribution to the new species.

Diagnosis. Males of L. lifengyuanae sp. n. are most similar to those of L. ziboensis sp. n. They can be distinguished from the latter by the anterior distal apophysis of the conductor dorsal edge enlarged while the posterior distal apophysis of the conductor dorsal edge is small ( Fig. 1B ) vs. the anterior distal apophysis of the conductor dorsal edge small while the posterior distal apophysis of the conductor dorsal edge is enlarged in L. ziboensis sp. n. ( Fig. 6B ). Females of L. lifengyuanae sp. n. are most similar to those of other Lineacoelotes species. They can be distinguished from congeners by having long fertilization ducts ( Fig. 2B ) and tips of the epigynal teeth that bend abruptly ( Fig. 2A ).

Description. Male (holotype). Carapace and clypeus brown, endites and labium dark brown, colour of sternum the same as carapace, legs brown but lighter than carapace.

Abdomen 3.64 long, 2.38 wide. Eye sizes and interdistances: AME 0.12, ALE 0.19, PME 0.22, PLE 0.21; AME-AME 0.05, AME-ALE 0.09, AME-PME 0.09, ALE-PLE 0, PME-PME 0.10, PME-PLE 0.11.

Chelicera with 3 promarginal and 2 retromarginal teeth. Palp: femur 3.2 times longer than wide; patella 2.2 times longer than wide; tibia 3.1 times longer than wide; patella seta the same length as patella; patellar apophysis bent and long, extending to the anterior margin of the tibia, with pointed tip; retrolateral tibial apophysis wider than patellar apophysis, extending over tibia and with a blunt tip; cymbial furrow about 1/2 the length of the cymbium; embolus distorted, originating at 6 o’clock position; conductor with two apophyses (C2 and C3), one broad groove and one broad lamella; median apophysis spoon-shaped in ventral view; fertilization duct point to the left, colour lighter than spermathecal colour ( Fig. 1 A–C).

Female (IZCAS -Ar39284). Abdomen grey-brown, otherwise same as in male. Total length 9.94. Carapace 4.17 long, 2.56 wide.Abdomen 5.77 long, 3.85 wide. Eye sizes and interdistances:AME 0.11, ALE 0.16, PME 0.15, PLE 0.17; AME-AME 0.10, AME-ALE 0.08, AME-PME 0.10, ALE-PLE 0, PME-PME 0.05, PME-PLE 0.11.
