Relation to host.
Vagrant on leaf surface. No damage to the host was observed.
Etymology.
The specific designation
albosinensis
is from the species name of host plant,
albosinensis
.
Differential diagnosis.
This species is similar to
Anthocoptes insulanaes
Huang & Wang, 2004
, but can be differentiated from the latter by having the admedian lines separated on the prodorsal shield (admedian lines connected on prodorsal shield in
Anthocoptes insulanaes
), coxal plates II with granules (coxal plates II smooth in
Anthocoptes insulanaes
), and tarsal empodium 5-rayed (tarsal empodium 7-rayed in
Anthocoptes insulanaes
).
