Latouchia wenruni Lin & Li, 2023

Latouchia wenruni Lin & Li , sp. nov. ( Figs 9–10 View Figure 9 View Figure 10 )

Etymology. The species is named after Mr. Run Wen, the collector of the holotype and paratypes; noun (name) in genitive case.

Diagnosis. The male of the new species is similar to that of L. yuanjingae Lin & Li, 2022 by the straight embolus and the length of embolus is as long as the bulb, but it can be distinguished by the serrated embolus in ventral view ( vs. smooth in L. yuanjingae ) and lacking bristles laterally on the tibia tip ( vs. present in L. yuanjingae ). The female of the new species can be distinguished from those of L. yejiei Zhang & Wang, 2021 by the prominent spermathecal heads ( vs. absent in L. yejiei ).

Eye sizes and interdistances: AME 0.16, ALE 0.29, PME 0.21, PLE 0.28, AME–AME 0.07, AME–ALE 0.07, PME–PME 0.30, PME–PLE 0.02, AME–PME 0.09, ALE–PLE 0.09. Chelicerae with five promarginal and five retromarginal teeth. Leg measurements: I 14.18 (4.34, 5.08, 2.91, 1.85), II 12.59 (3.81, 4.16, 2.82, 1.80), III 10.52 (2.88, 3.05, 2.70, 1.89), IV 15.14 (4.16, 5.04, 3.85, 2.09).

Opisthosoma oval, dark brown, dorsum with numerous irregular white spots, laterally brown, ventrum yellow-brown. Spinnerets short, yellow-brown.

Palp ( Fig. 9 View Figure 9 ). Tibia four times longer than wide, bristles on lateral side of tip are stout. Embolus slightly curved, tip with five serrations and an apophysis.

Female (IZCAS-Ar43840). Total length 18.23; carapace 8.54 long, 7.23 wide, opisthosoma 9.69 long, 6.61 wide. Eye sizes and interdistances: AME 0.26, ALE 0.43, PME 0.21, PLE 0.34, AME–AME 0.16, AME–ALE 0.22, PME–PME 0.58, PME–PLE 0.14, AME–PME 0.16, ALE–PLE 0.33. Chelicerae with six promarginal and eight retromarginal teeth. Leg measurements: I 18.64 (6.27, 7.39, 3.14, 1.84), II 15.28 (5.32, 5.57, 2.67, 1.72), III 14.22 (4.62, 5.23, 2.22, 2.15), IV 20.51 (6.29, 7.54, 4.19, 2.49).

Coloration ( Fig. 10C View Figure 10 ). Similar to that of male except paler.

Endogyne ( Fig. 10A View Figure 10 ). Spermathecae sock shaped, with numerous glandular pores; stalks almost as wide as spermatheca.
