Types
.
Holotype
, female, from
Lindera
sp. (
Lauraceae
), Wen County, Gansu Province,
China
, 32°56'43N, 104°40'27E,
September 9, 2005
, collected by Zi-Wei Song and Xiao-Feng Xue.
Paratypes
,
11 females
, with the same data as
holotype
.
Relation to host.
Mites are vagrant on the undersurface of leaves, causing no apparent damage.
Etymology.
The specific designation
linderanis
is from the generic name of the host plant,
Lindera
.
Remarks.
This species is similar to
Calepitrimerus linderaus
Huang & Cheng, 2005
, but can be differentiated by coxal area with short lines and granules (coxal area smooth in
C
.
linderaus
), prodorsal shield design without median line (prodorsal shield design with un-continuous median lines in
C
.
linderaus
), tarsal solenidion tapered (tarsal solenidion knobbed in
C
.
linderaus
).
