Paratypes
,
7 females
and
2 males
(slides marked NJAUAcariEri879) with the same data as
holotype
.
Relation to host.
Vagrant on leaf undersurface. No damage to the host was observed.
Etymology.
The specific designation
cunninghamiae
is from the host genus name “
Cunninghamia
”.
Differential diagnosis.
This species is similar to
P
.
dimidius
Huang, 2001
, but can be differentiated by the prodorsal shield design with median line complete, submedian lines incomplete, admedian lines sinuous, median and admedian lines connect with a V-shaped line at 1/4 from anterior (prodorsal shield design with median line from base to middle, parallel with median line, with 3 transverse lines at basal 1/4, middle and 3/ 4, submedian lines complete, converging to apex, subparallel with admedian lines in
