Paratypes
:
4 males

3 females
(IZCAS), same data as

.
Etymology.
The specific name is from Latin
viriosus
(strong), in reference to the large size of the species; adjective.
Diagnosis.
Male differs from
C. acris
sp. nov.
,
C. bawangensis
sp. nov.
,
C. falcata
sp. nov.
,
C. gracilis
sp.
nov.
,
C. jianfengensis
sp. nov.
,
C. liaoi
(Peng & Li, 2006),
C. sanyaensis
sp. nov.
and
C. setifera
sp. nov.
by having a large patellar apophysis (

; 1, 5; 7, 11; 13, 17; 19, 25; 32, 38; 45, 49; 51, 57; 64, 70); differs from
C. wuzhishanensis
sp. nov.
by having a branched patellar apophysis, and the two branches of median apophysis which are approximately equal in length (
Figs 77
,
83
; 92, 98). Female can be distinguished from
C. wuzhishanensis
sp. nov.
by the proportion of epigyne length and width (

; wider than longer in
C. wuzhishanensis
sp. nov.
