sp. nov.

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 ).

Description. Male (holotype). Total length 9.71; carapace 4.72 long, 4.16 wide, opisthosoma 4.99 long, 3.37 wide. 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).

Coloration ( Fig. 10B View Figure 10 ). Carapace dark brown to brown, covered with black setae. Chelicerae dark brown. Endites and labium red-brown. Sternum yellow-brown. Legs brown with black setae. 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.

Material examined. Holotype ♂ (IZCAS-Ar43837), China: Hainan, Changjiang Li Autonomous County, Bangxi Baomeiling (19.2815°N, 109.0987°E, elev. 603 m), 13 September 2022, Run Wen, Chengbin Wen and Neng Guo leg. Paratypes. 3♀ (IZCAS-Ar43838–Ar43840), same data as holotype GoogleMaps .
