Type
material.
Holotype
, female (slide marked NJAUAcariEri891
holotype
), from
Swida macrophylla
(Wall.) Sojak (Cornaceae)
, Bayi Town, Nyingchi Prefecture, Tibet Autonomous Region, P. R.
China
(29°37΄01ʺN, 94°42΄00ʺE; H:

Paratypes
,
9 females
(slides marked NJAUAcariEri891) with the same data as
holotype
.
Relation to host.
Vagrant on leaf undersurface. No damage to the host was observed.
Etymology.
The specific designation
swidanus
is from the host genus name “
Swida
”.
Differential diagnosis.
This species is similar to
C. regiae
Xue, Song & Hong, 2006
, but can be distinguished by prodorsal shield without median line (prodorsal shield with incomplete median line in
C. regiae
); coxal plates smooth (coxal plates with short lines in
C. regiae
); ventral annuli with round microtubercles (ventral annuli with spiny microtubercles in
C. regiae
).
