Relation to host.
Mites are vagrant on the undersurface of leaves, causing no apparent damage.
Etymology.
The specific designation
baisensis
is derived from the geographic area in which it was collected.
Notes.
This species is similar to
Disella octcella
Huang 2001
, but can be differentiated by prodorsal lateral shield design with network and dashes, coxal area with granules, accessory setae (
h1
) absent (
D. octcella
shield sides with short lines, coxal area smooth, accessory setae (
h1
) present).
