Type material.

Holotype: China • ♂; Yunnan Province, Pingbian County, Daweishan National Forest Park (22°59'16''N, 103°57'01''E, 2124 m elev.), 28 October 2016, Guiqiang Huang leg. Paratypes: • 3♀2♂, same data as holotype.

Etymology.

The species name is derived from the Latin camela (camel), referring to hump-shaped retrolateral tibia apophyses in retrolateral view; noun.

Diagnosis.

The new species resembles C. biforamina Liu, Peng & Yan, 2016 ( Liu et al. 2016: figs 1-12), but it differs by the larger embolus length/conductor length ratio (1.6 vs. 0.6), triangle distal retrolateral tibia apophyses (vs. trapezoidal), the copulatory openings located almost centrally (vs. anteriorly), the coiled copulatory ducts (vs. U-shaped), the pear-shaped bursae (vs. oblong).

Description.

Male (Fig. 4A ). Holotype total length 6.21. Carapace 2.80 long, 1.99 wide; abdomen 3.51 long, 1.70 wide. Carapace yellowish brown. In dorsal view, anterior eye row recurved, posterior eye row almost straight. Eye sizes and interdistances: AME 0.12, ALE 0.15, PME 0.12, PLE 0.14; AME-AME 0.11, AME-ALE 0.06, PME-PME 0.25, PME-PLE 0.17, ALE-PLE 0.08. MOA 0.38 long, front width 0.34, back width 0.50. Clypeus height 0.09. Chelicerae yellowish, promargin with 5 teeth, retromargin with 6 teeth. Labium 0.52 long, 0.36 wide. Sternum 1.46 long, 1.03 wide. Endites yellow, longer than wide. Abdomen oval, brownish yellow, with conspicuous anterior tufts of setae; dorsum of abdomen with fine, yellow hairs; cardiac pattern brown. Spinnerets and legs yellow brown. Leg measurements: I 8.58 (2.40, 1.05, 2.43, 1.81, 0.89), II 12.31 (3.48, 1.20, 3.56, 2.83, 1.24), III 8.10 (2.67, 0.89, 1.80, 2.05, 0.69), IV 10.14 (2.92, 0.93, 2.42, 2.98, 0.89). Leg formula: 2-4-1-3.

Palp (Figs 4B-D , 5C-E ). Patella length/width ratio 1.7, with a small ventral apophysis. Patella length/tibia length 1.4. Tibia length/width ratio 1.1, with 2 thumb-shaped RTA in ventral view, hump-like in retrolateral view. Cymbium length/width ratio 3.1. Conductor length/width ratio 2.4, with oval base and beak-shaped distal part in retrolateral view, arose from retrolateral tegulum, then extended prolaterally. Embolus slender, rising from retrolatero-distal tegulum, gradually tapering, then extending to prolateral part of cymbium. Sperm duct obvious, S-shaped in prolateral view.

Female (Fig. 3A ). Total length 6.12-6.51. One paratype measured: total length 6.51, carapace 2.77 long, 2.06 wide; abdomen 3.78 long, 2.03 wide. Eyes sizes and interdistances: AME 0.11, ALE 0.15, PME 0.12, PLE 0.14; AME-AME 0.12, AME-ALE 0.08, PME-PME 0.28, PME-PLE 0.19, ALE-PLE 0.11. MOA 0.40 long, front width 0.35, back width 0.52. Clypeus height 0.07. Labium 0.48 long, 0.34 wide. Sternum 1.52 long, 1.07 wide. Leg measurements: I 6.57 (1.90, 0.98, 1.73, 1.25, 0.71), II 7.33 (2.10, 1.00, 1.98, 1.50, 0.75), III 6.18 (1.84, 0.83, 1.35, 1.56, 0.60), IV 8.41 (2.32, 0.99, 1.95, 2.35, 0.80). Leg formula: 4-2-1-3. Coloration slightly lighter than in male. Other characters as in male.

Epigyne (Figs 3B, C , 5A, B ). Epigynal plate as long as wide, obviously sclerotised. Copulatory openings close to each other, located almost centrally. Copulatory ducts curved, connected with bursae at anterior part of epigyne. Bursae pear-shaped, close to each other, 1.6 × longer than wide. Spermathecae long, tubular, located on dorsal-inner surface of bursae. Fertilisation ducts thin and short.

Distribution.

Presently known only from Yunnan, China.
