Etymology. The specific name is a patronym in honor of the late Mr. Zuwei Zha, the collector of the
holotype
; noun in apposition. Graduated with a M.Sc degree from the
Guizhou
Nornal Univeristy in 2011, he worked on the taxonomy of the spider families of
Atypidae
and
Hexathelidae
. Mr. Zha passed away in 2013 at the age of 30.
Diagnosis. This new species is similar to
C. kailiensis
Li
,
sp. nov.
(
Figs 73–77
), but can be distinguished by the longerthan-wide atrium (atrium wider than long in
C. kailiensis
Li
,
sp. nov.
), the bursae reaching the apex of spermathecae (just reaching base of spermthecae in
C. kailiensis
Li
,
sp. nov.
), and the laterally extended part of copulatory ducts pointing postero-medially (pointing posterior-laterally in
C. kailiensis
Li
,
sp. nov.
).
Description. Female (
holotype
). Total length 2.51 (
Figs 89C–D
). Prosoma length 1.18, width 0.90. Cephalic region width 0.57. Cephalic part flat, covered with several setae. Thoracic part light brown, fovea reduced, prosoma margin indistinct. Eight eyes, AME black, others white, all eyes encircled with black. Eye diameters: AME 0.05, ALE 0.07, PLE 0.09, PME 0.07. Eye interdistances: ALE-PLE 0.01, AME-ALE 0.02, AME-AME 0.02, PLE-PME 0.04, PME-PME 0.07. Eye region length 0.35, width 0.18. Clypeus height 0.08. Chelicerae length 0.57, width 0.26. Chelicerae brown, with distinct lateral condyles, 3 (1 large, 2 small) promarginal and 8 retromarginal teeth. Labium and gnathocoxae brown; sternum yellow. Labium length 0.15, width 0.22. Gnathocoxae length 0.32, width 0.20. Sternum length 0.70, width 0.60. Legs light brown. Leg formula IV-I-II-III. Leg measurements: I 3.43 (1.00, 0.38, 0.87, 0.73, 0.45); II 3.26 (0.98, 0.38, 0.75, 0.68, 0.47); III 2.81 (0.80, 0.33, 0.60, 0.64, 0.44); IV 3.74 (1.10, 0.38, 0.88, 0.88, 0.50). Opisthosoma length 1.35, width 1.08. Opisthosoma yellow, with two rows of gray spots. No cribellum and no calamistrum.
