Belisana honghe Zhang, Li & Yao sp. nov. Figs 2, 3, 18 A, B, 20 A, B Type material. Holotype ♂ (IZCAS - Ar 44949) and paratypes 2 ♂ (IZCAS - Ar 44950 –51) 3 ♀ (IZCAS - Ar 44952 –54), Yanzi Cave (23 ° 38.220 ' N, 103 ° 3.200 ' E, 1080 m), Mawangzhuang, Miandian Town, Jianshui County, Honghe, Yunnan, China, 29 / 03 / 2007, J Liu & Y Lin leg. Etymology. The specific name refers to the type locality, which is a noun in apposition. Diagnosis. The new species resembles B. cheni Yao, Pham & Li, 2015 (Yao et al. 2015: 5, figs 4 A – D, 5 A – G, 6 A – E) by having similar male chelicerae, bulbal apophyses, and epigyne (Figs 3 A, C, D, 20 A), but can be distinguished by differences in males: procursus with nearly trapezoidal dorso-distal membranous process (arrow 3 in Figs 2 C, 18 A vs half-round) and long (as long as dorso-distal membranous process), distally widened ventro-subdistal membranous process (arrow 4 in Figs 2 C, 18 A vs short and distally pointed); differences in females: pore plates anteriorly pointed and posteriorly wide and blunt (Figs 3 B, 20 B vs narrow). Description. Male (holotype): Total length 1.66 (1.74 with clypeus), carapace 0.63 long, 0.67 wide, opisthosoma 1.03 long, 0.84 wide. Leg I: 19.02 (5.05, 0.26, 5.00, 7.05, 1.66), leg II: 14.38 (3.96, 0.25, 3.80, 5.15, 1.22), leg III missing, leg IV: 10.65 (3.16, 0.23, 2.53, 3.96, 0.77); tibia I L / d: 89. Eye inter-distances and diameters: PME – PME 0.13, PME 0.07, PME – ALE 0.02, AME absent. Sternum width / length: 0.50 / 0.46. Habitus as in Fig. 3 E, F. Carapace and sternum yellowish, without marks. Legs whitish, without darker rings. Opisthosoma yellowish, without spots. Thoracic furrow absent. Clypeus unmodified. Chelicerae (Fig. 3 D) with a pair of proximo-lateral apophyses and a pair of distal apophyses (distance between tips: 0.19). Palp as in Fig. 2 A, B; trochanter with ventral apophysis (arrow 2 in Fig. 2 B) and prolateral apophysis (arrow 1 in Fig. 2 B); procursus simple proximally but complex distally, with sclerotized prolatero-distal apophysis (arrow 1 in Figs 2 C, 18 A), sclerotized distal apophysis (arrow 2 in Figs 2 C, 18 A), dorso-distal membranous process (arrow 3 in Figs 2 C, 18 A), ventro-subdistal membranous process (arrow 4 in Figs 2 C, 18 A), and retrolateral flap (Figs 2 D, 18 B); bulb (Fig. 3 C) with hooked apophysis and simple embolus. Retrolateral trichobothria on tibia I at 9 % proximally; legs with short vertical setae on metatarsi; tarsus I with 20 distinct pseudosegments. Female (paratype, IZCAS - Ar 44952): Similar to male, habitus as in Fig. 3 G, H. Total length 1.50 (1.62 with clypeus), carapace 0.49 long, 0.55 wide, opisthosoma 1.01 long, 0.80 wide; tibia I: 3.60; tibia I L / d: 61. Eye inter-distances and diameters: PME – PME 0.14, PME 0.06, PME – ALE 0.02, AME absent. Sternum width / length: 0.47 / 0.44. Epigyne (Figs 3 A, 20 A) simple and flat, with a pair of postero-lateral pockets 0.32 apart (arrow ep in Figs 3 B, 20 B, invisible in Figs 3 A, 20 A). Vulva (Figs 3 B, 20 B) with ridge-shaped anterior arch and a pair of anteriorly pointed and posteriorly wide and blunt pore plates. Variation. Tibia I in one male paratype (IZCAS - Ar 44950) (leg I missing in IZCAS - Ar 44951): 5.64. Tibia I in the other two female paratypes (IZCAS - Ar 44953 –54): 4.10, 4.25. Habitat. The species was found in the dark zone inside the cave. Distribution. China (Yunnan, type locality; Fig. 1).
