Holotype.

♀ (IZCAS-Ar 34754), China: Yunnan Province: Xishuangbanna: Mengla County: Menglun Town: XTBG, Paramichelia baillonii Clubiona plantation , 21°53.823'N, 101°17.072'E, ca. 613 m, 1-17.II.2007, G. Zheng leg.

Etymology.

This species is named after Mr. Yejie Lin (Beijing City, China) who has helped us greatly with this research.

Diagnosis.

The new species is similar to C. cochlearis (Figs 1A-E View Figure 1 , 73A View Figure 73 , 81A View Figure 81 , 89A View Figure 89 ) in the general appearance of the atrium and endogyne. From C. cochlearis , the female of the new species can be easily distinguished by the shape of the atrium and spermathecae: (1) atrium ellipsoid (Figs 23A-C View Figure 23 , 73C View Figure 73 , 81C View Figure 81 ) (vs. atrium apple-shaped; Figs 1A-C View Figure 1 , 73A View Figure 73 , 81A View Figure 81 ); (2) spermathecae thicker and not twisted, diameter ca. 1/3 of atrium length (Figs 23D, E View Figure 23 , 89C View Figure 89 ) (vs. thinner and strongly convoluted, diameter not more than 1/8 of atrium length; Figs 1D, E View Figure 1 , 89A View Figure 89 ).

Description.

Female. Holotype (Fig. 23F, G View Figure 23 ). Total length 9.47; carapace 4.47 long, 2.56 wide; opisthosoma 5.50 long, 3.82 wide. Carapace brownish red, pars cephalica slightly darker in ocular area, without markings, cephalic region slightly narrowed, cervical groove indistinct; tegument smooth, covered with numerous fine setae. Eyes: AER slightly recurved, PER slightly procurved, PER wider than AER. Eye sizes and interdistances: AME 0.17, ALE 0.17, PME 0.17, PLE 0.09, AME-AME 0.25, AME-ALE 0.85, PME-PME 0.45, PME-PLE 0.47, MOQL 0.55, MOQA 0.58, MOQP 0.79. Chelicerae robust and protruding, coloured as ocular area, with four promarginal and two retromarginal teeth. Sternum centrally orange and marginally red, 2.13 long, 1.36 wide. Labium and endites coloured as chelicerae. Legs light orange, uniformly coloured, without pattern. Leg measurements: I 8.64 (2.33, 3.63, 2.03, 0.64), II 8.73 (2.76, 3.60, 1.44, 0.93), III 8.16 (2.51, 2.96, 1.77, 0.92), IV 10.54 (3.32, 3.48, 2.60, 1.14). Abdomen uniformly cream coloured, dorsum with two pairs of conspicuous muscle depressions; venter medially with two longitudinal broken lines.

Epigyne (Figs 23A-E View Figure 23 , 73C View Figure 73 , 81C View Figure 81 , 89C View Figure 89 ). Epigynal plate slightly longer than wide, through which bursae and copulatory ducts are easily visible. Atrium shaped like an irregular ellipse, ca. 1.3 × wider than long, ca. 1/5 epigyne length. Copulatory openings indistinct, located at basolateral atrial borders. Copulatory ducts short and thick, heavily sclerotised, running laterally, bent 90 degrees dorsally and then obliquely descending, connecting with tubular spermathecae. Spermathecae long and sinuous, with even thickness throughout. Fertilisation ducts acicular, membranous, located terminally on spermathecae. Bursae large and oblong, close together, ca. 1.5 × longer than wide, surface translucent and wrinkled.

Male. Unknown.
