Abstract: Cicurina yinhe sp. nov. Figs 1 C, 4 A – G, 5 A – G, 8 银河洞叶蛛 Type material. Holotype • male (SWUC -T-CI-14-01), China, Chongqing, Beibei, Shuitu Town, Wuji Valley, Yinhe Cave, 29°50'4"N, 106°29'51"E, elev. 550 m, 23 November 2021, L. Y. Wang and T. Y. Ren leg. Paratypes: • 9 males and 3 females (SWUC -T-CI-14-02 –13), with same data as for holotype. Etymology. The specific name refers to the type locality. Diagnosis. This new species is similar to C. lichuanensis Wang, Zhou & Peng, 2019 (Wang et al. 2019: figs 5 A – D, 6 A – G) in having the similar shaped retrolateral tibial apophysis, the long and strong embolus, the posteriorly located epigynal atrium, and the ball-shaped spermathecae, but differs by the wider and slightly curved retrolateral tibial apophysis (Figs 4 B, 5 E) (vs. wide and more curved in C. lichuanensis), the sharp conductor end (Figs 4 A, B, 5 C – E) (vs. blunt in C. lichuanensis), and the wide epigynal atrium (Figs 4 C, D, 5 F, G) (vs. wider in C. lichuanensis). Description. Male holotype (Fig. 5 A) total length 4.92. Prosoma 2.57 long, 2.15 wide; opisthosoma 2.40 long, 1.71 wide. Carapace pyriform and yellow, with a few setae. Eye sizes and interdistances: AME 0.10, ALE 0.14, PME 0.14, PLE, 0.15; AME – AME 0.06, AME – ALE 0.02, PME – PME 0.12, PME – PLE 0.08, ALE – PLE 0.04. MOA 0.35 long, anterior width 0.28, posterior width 0.41. Clypeus height 0.31. Chelicerae with three promarginal and six retromarginal teeth. Leg measurements: I 7.37 (2.02, 2.59, 1.75, 1.01); II 6.81 (1.89, 2.29, 1.63, 1.00); III 6.07 (1.73, 1.92, 1.50, 0.92); IV 7.83 (2.04, 2.49, 2.18, 1.12). Leg formula: 4123. Opisthosoma oval, yellow and hairy, without distinct patterns. Palp (Figs 4 A, B, 5 C – E). Retrolateral tibial apophysis wide, with a single fold and truncates apex. The base of retrolateral tibial apophysis with two small apophyses, extending ventrally and dorsally. Embolus strong, originating at approximately 9 - o’clock position, with the anterior part extending along the groove of the conductor. Conductor strong, with a small and hooked end. One of female paratypes (SWUC -T-CI-14-02, Fig. 5 B) total length 4.40. Prosoma 2.25 long, 1.55 wide; opisthosoma 2.27 long, 1.69 wide. Carapace pyriform and yellow, with a few setae. Eye sizes and interdistances: AME 0.11, ALE 0.13, PME 0.12, PLE, 0.14; AME – AME 0.06, AME – ALE 0.02, PME – PME 0.11, PME – PLE 0.07, ALE – PLE 0.02. MOA 0.37 long, anterior width 0.27, posterior width 0.36. Clypeus height 0.13. Chelicerae with three promarginal and six retromarginal teeth. Leg measurements: I 5.29 (1.75, 2.19, 1.28, 0.77); II 4.43 (1.51, 1.84, 1.16, 0.76); III 4.28 (1.43, 1.54 1.15, 0.69); IV 5.75 (1.84, 2.12, 1.59, 0.85). Leg formula: 4123. Opisthosoma oval, yellow and hairy, without distinct patterns. Epigyne (Figs 4 C, D, 5 F, G). Atrium oval. Copulatory openings located on the shoulders of atrium. Spermathecae large and ball-shaped. Fertilization ducts hook-shaped. Variation. Males (N = 8) total length 4.13–4.92; females (N = 3) total length 3.94–4.40.
