Selenops crewsae Lin & Li , sp. nov. ( Figs 30A–B , 31A–B )

Diagnosis. Selenops crewsae Lin & Li , sp. nov. can be distinguished from S. ollarius Zhu, Sha & Chen, 1990 by the length ratio of the median field to the width of the Se, which is almost 1:1 (vs. 1: 2 in S. ollarius ); conspicuous EP (vs. no apparent EP in S. ollarius ); LL not extend posteriorly in S. crewsae Lin & Li , sp. nov. (vs. extend beyond the plate medially and are pointed in S. ollarius ) and S swell at the middle (vs. hollow in S. ollarius ).

Description. Female (holotype, IZCAS-Ar42433, Figs 30A–B , 31A–B ). Total length 10.46. Carapace 3.91 long, 4.61 wide. Abdomen 6.55 long, 4.55 wide. Eye sizes and interdistances: AME 0.19, ALE 0.17, PME 0.28, PLE 0.44; AME–AME 0.18, AME–ALE 0.08, PME–PME 0.72, PME–PLE 0.51. Leg measurements: Leg I 15.08 (4.56 + 6.05 + 3.00 + 1.47); leg II 17.98 (5.83 + 7.20 + 3.40 + 1.55); leg III 16.95 (5.90 + 6.30 + 3.35 + 1.40); leg IV 15.27 (5.13 + 5.65 + 3.16 + 1.33). Spination: Leg I tibia ventral 2.2.2; metatarsus ventral 2.2; leg II tibia ventral 2.2.2; metatarsus ventral 2.2. Promargin and retromargin of chelicerae with 3 teeth. Carapace yellowish with black lateral margins. Abdomen yellow with black pattern. Legs brownish, with black annulations.

Epigyne ( Figs 30A–B ) subtriangular; epigynal plate broad, width ca. 1 to 1.5 of length; median field with a lobe, lobe nose shaped; EP, do not reach the caudal margin, COs inconspicuous; S nearly oval; FDs long.

Male. Unknown.

Material examined. Holotype ♀, China: Sichuan Province, Ganzi Zang Autonomous Region, Zhubalong , Gunre , under rocks (29.6703°N, 98.9961°E; elev. ca. 2450 m), 18 July 2019, leg. Yan Tong (IZCAS-Ar42433) . Other material examined: 2j (IZCAS-Ar42434–Ar42435), same data as holotype; 2j (IZCAS-Ar42436–Ar42437), same data as holotype, but 6 August 2019, leg. Shuo Qi and Chao Wu ; 3j (IZCAS-Ar42438–Ar42440), same data as holotype, but 14 June 2019, leg. Yejie Lin.

Distribution. Known only from the type locality.

Etymology. The species is named after Miss Sarah Crews, a leading taxonomist in Selenopidae ; noun (name) in genitive case.
