VIII. 2008; leg. Tingbang Yang • 1 ♂ 7 ♀ (CLU 1441-1 – CLU 1441-8); Cang Shan; 2600 m elev.; 9. VIII. 2011; leg. Qiuju Wei. Etymology. The specific name comes from the combination of “multi-” and “processus”, referring to the multiple (six) apophysis on the male palp; an adjective. Diagnosis. The male of C. multiprocessa sp. nov. can be distinguished from all other members of the C. corticalis group except for C. longyangensis sp. nov. (Fig. 2). Refer to the detailed diagnosis above for the similarities and differences between the two. The females of the new species (Fig. 6) resembles C. applanata Liu, Yan, Griswold & Ubick, 2007 (Liu et al. 2007: 64, figs 1, 2), C. dichotoma Wang, Chen & Zhang, 2018 (Wang et al. 2018: 319, figs 2 C, D, 3 F, G), C. subapplanata Wang, Chen, Zhang, 2018 (Wang et al. 2018: 327, figs 14 C, D, 15 E, F), and C. lamellaris Zhang, Yu, Zhong, 2018 (Zhang et al. 2018: 396, figs 3 F, G, 4 D, E) in the general shape of vulva, but the new species can be distinguished by the following: (1) epigynal plate wider than long (vs longer than wide in the other four species); (2) anterior surface of spermathecae with a papilliform appendage (vs absent in the other four species). Description. Male (holotype) (Fig. 4 A, B): total length 3.34. Carapace 1.67 long, 1.21 wide; abdomen 1.67 long, 0.98 wide. Carapace uniformly orange-yellow, with indistinct radial striae. Fovea longitudinal, dark. AER slightly recurved, PER wider than AER, almost straight in dorsal view. Eye sizes and interdistances: AME 0.07, ALE 0.10, PME 0.08, PLE 0.11; AME – AME 0.03, AME – ALE 0.01, PME – PME 0.14, PME – PLE 0.10. MOA 0.26 long, front width 0.18, back width 0.31. Chelicerae yellow-brown, with four promarginal and five retromarginal teeth, with dense scopula in both margins. Clypeus height 0.02. Sternum pale yellow, 0.95 long, 0.63 wide. Labium coloured as chelicerae, anterior edge with dark scopula. Endites reddish brown. Legs pale yellow, tibia, metatarsus, and tarsus slightly darker in colour. Leg measurements: I 3.15 (0.85, 0.48, 0.72, 0.69, 0.41), II 3.69 (0.95, 0.45, 1.08, 0.78, 0.43), III 3.06 (1.07, 0.32, 0.64, 0.68, 0.35), IV 4.48 (1.46, 0.45, 0.84, 1.22, 0.51). Abdomen elongate-oval, dorsum yellowish brown, with conspicuous anterior tufts of hairs and many scattered darker spots. Palp (Fig. 5). Femur with a slanting finger-like retrolateral apophysis (RFA), ca 3 / 4 of femur’s length. RFA partly membranous, arising mesially from femur, directing retrolatero-dorsally. Patella with two apophyses: PPA broad and blunt, located medially, shaped like an equilateral triangle in ventral view; RPA short, ca 1 / 3 of patella’s length, slightly curved at apex in ventral view, more or less inverted V-shaped in retrolateral view, located distally. Tibia slightly shorter than patella, with three apophyses: RTA short and blunt, ca 1 / 2 of tibia’s length in ventral view, broad, flat, and with blunt apex in retrolateral view; VTA papilliform, short and transparent; LTA ridge-like, near the base of tibia. Cymbium almost 1.6 × longer than wide. Tegulum elongated oval, ca 1.4 × longer than wide; subtegulum visible prolaterally. Sperm duct sinuate, nearly U-shaped in ventral view. Embolus (E) arising from distal portion of tegulum, shaped like an isosceles triangle in ventral view, broad at base, gradually tapering toward apex. Conductor (C) large, originating from retrolateral side of tegulum, about 2 o’clock position, approximately 7 - shaped in ventral view, distal part gradually tapering, extended transversely to the base of embolus. Female (paratype) (Fig. 4 C, D): one specimen body length 3.75. Carapace 1.68 long, 1.33 wide; abdomen 2.07 long, 1.47 wide. Carapace orange, clothed with short fine hairs. Eye sizes and interdistances: AME 0.08, ALE 0.09, PME 0.09, PLE 0.09; AME – AME 0.05, AME – ALE 0.04, PME – PME 0.18, PME – PLE 0.11. MOA 0.26 long, front width 0.21, back width 0.37. Clypeus height 0.02. Sternum 1.01 long, 0.64 wide. Chelicerae, labium, and endites coloured as carapace. Leg measurements: I 3.29 (0.96, 0.51, 0.88, 0.54, 0.40), II 3.45 (0.94, 0.53, 0.96, 0.63, 0.39), III 3.03 (0.74, 0.33, 0.85, 0.73, 0.38), IV 4.42 (1.29, 0.59, 1.14, 1.06, 0.34). Abdomen oval, dorsum greyish white, with a narrow longitudinal band in middle. Epigyne (Fig. 6). Epigynal plate slightly wider than long. Atrium (A) nearly heart-shaped, located at anterior portion of epigynal plate. Copulatory openings (CO) tiny, located centrally in atrium. Copulatory ducts (CD) invisible. Spermathecae (S) long, located at the anterior position of bursae, spermathecal heads (SH) ovate, with a papilliform spermathecal appendage (SA), spermathecal bases (SB) tubular, with small fertilisation ducts terminally (FD). Bursae (B) close together, nearly spherical, situated posteriorly. Distribution. Presently known only from Yunnan, China.
