Type
data:
Holotype
, female, Jinzhong MT.,
37 km
SW of Longlin County (
24°8´N
,
105°34´E
), Guangxi Zhuang Autonomous Region,
China
,
1 December 2004
, from
Cipadessa cinerascens
(Pellegr.) Hand.
-Mazz. (
Meliaceae
), coll. De-wei Li, Sui-gai Wei and Guo-quan Wang.
Paratypes
,
15 females
, with the same data as
holotype
.
Relation to host:
The mites are vagrant on the undersurfaces of the leaves, no visible damage.
Etymology:
The species name is derived from the name of the host plant.
Note:
This species is similar to
Calacarus pelargonii
Keifer, 1974
, but can be differentiated by prodorsal shield admedian lines form a burning-candle-like design; female coverflap with granules at base and tarsal empodium 5-rayed.
