Type
material.
Holotype
, female (slide marked NJAUAcariEri923

Paratypes
,
7 females
(slides marked NJAUAcariEri923) with the same data as
holotype
.
Relation to host.
Vagrant on leaf undersurface. No damage to the host was observed.
Etymology.
The specific designation
webbianae
is from the host species name “
webbiana
”.
Differential diagnosis.
This species is similar to
P. chonganensis
(
Kuang, 1987
)
, but can be differentiated by the prodorsal shield design with median and admedian lines separated, shield without short lines (prodorsal shield design with median and admedian lines connected with transverse line near posterior, shield with short lines in
P. chonganensis
); coxal plates with granules, prosternal apodeme absent (coxal plates with short lines, prosternal apodeme present in
P. chonganensis
); tarsal empodium 7-rayed (tarsal empodium 6-rayed in
P. chonganensis
).
