Hahnia zhuyifani Lin & Li , sp. nov. ( Figs 7–8 )

Etymology. The specific name is dedicated to Mr. Yifan Zhu (Beijing, China), who has helped us greatly with this research; noun (name) in genitive case.

Diagnosis. Females of the new species can be distinguished from all congeners by the extremely large lateral sulci, about 1/2 the length of the epigynal plate and by the weakly sclerotized and elongate spermathecae (vs. oval or round).

Description. Female (holotype). Total length 1.29, carapace 0.64 long, 0.41 wide, opisthosoma 0.91 long, 0.63 wide. Eye sizes and interdistances: AME 0.03, ALE 0.05, PME 0.07, PLE 0.04, AME–AME 0.01, AME–ALE 0.01, PME–PME 0.07, PME–PLE 0.02, AME–PME 0.05, ALE–PLE 0.01. Chelicerae with 4 promarginal and 8 retromarginal teeth. Leg measurements: I 1.26 (0.39, 0.41, 0.22, 0.24), II 1.13 (0.33, 0.37, 0.21, 0.22), III 1.00 (0.29, 0.32, 0.19, 0.20), IV 1.37 (0.41, 0.44, 0.26, 0.26).

Coloration ( Fig. 8 ). Carapace pale yellow, with gray radiating marks. Chelicerae, labium, gnathocoxae and sternum pale yellow. Legs pale yellow, covered with long setae. Opisthosoma oval, gray with dark pattern, covered with long setae; venter gray without pattern. Spinnerets white.

Epigyne ( Fig. 7 ). Epigynal plate 1.35 times wider than long. Lateral sulci two times wider than long. Copulatory openings located medially, fissured, touching each other. Copulatory ducts intertwined, basal part with glandular appendages, medial and distal part with U-shaped fold. Glandular appendages round. Spermathecae oval, 4 times wider than long. Fertilization duct directed at 10:00-o’clock-position from spermatheca.

Male. Unknown. Material examined. Holotype ♀ (IZCAS-Ar44793), China: Yunnan, Jianshui Co., Yunlong Mountain (23.7841°N, 107.04108°E, elev. 1939 m), 25.V.2015, Fengyuan Li and Zhigang Chen leg. Paratypes. 4♀ (IZCAS-Ar44794–Ar44797), same data as holotype. Distribution. Known only from the type locality .
