Etymology. The specific name is derived from the Latin word “ parallelus ”, meaning “parallel”, and refers to the ventral view of the female copulatory ducts; adjective.

Diagnosis. Females of this species are most similar to C. dong Li , sp. nov. ( Figs 70 View Figure 70 , 72A–B View Figure 72 ), but can be distinguished by the posteriorly located atrium (anteriorly situated in C. dong Li , sp. nov.), and the end of copulatory ducts not extending laterally (extending laterally in C. dong Li , sp. nov.).

Description. Female (holotype). Total body length 2.25 ( Figs 82C–D View Figure 82 ). Prosoma length 1.05, width 0.90. Cephalic region width 0.55. Cephalic part relatively flat, brown, covered with several setae. Thoracic part dark brown, fovea reduced. Eight eyes, AME black, others white. All eyes encircled with black. PER straight. Eye diameters: AME 0.04, ALE 0.07, PLE 0.07, PME 0.07. Eye region length 0.16, width 0.37. Eye interdistances: AME-AME 0.03, AME-ALE 0.03, ALE-PLE 0.02, PLE- PME 0.05, PME-PME 0.07. Clypeus height 0.08. Chelicerae length 0.43, width 0.28. Chelicerae with distinct lateral condyles, 3 promarginal and 8 retromarginal teeth. Labium length 0.13, width 0.21.

Opisthosoma length 1.43, width 1.13. Opisthosoma white, with black anchor shaped pattern. Venter without distinct pattern. Spinnerets yellow-brown. No cribellum and no calamistrum.

Epigynum ( Figs 81 View Figure 81 , 82A–B View Figure 82 ). Width 0.38. Atrium posteriorly located on epigynal plate. Copulatory ducts inverted “ V ” in ventral view, parallel. Bursae enlarged, slightly fused at base. Copulatory ducts slender, internally joining base of spermathecae. Spermathecae spherical, widely separated. Fertilization duct long, medially attached at base of spermathecae.

Male. Unknown.
