Paratypes
,
18 females
and
10 males
(slides marked NJAUAcariEri973/974) with the same data as
holotype
.
Relation to host.
Vagrant on leaf undersurface. No damage to the host was observed.
Etymology.
The specific designation is
smilanus
from the host genus name “
Smilax
”.
Differential diagnosis.
This species is similar to
P
.
kuangii
Amrine & Stasny, 1994
(
Kuang & Zhuo, 1989
)
, but can be distinguished by the shield design with incomplete median line only present on 1/3 of shield and subparallel with admedian lines; admedian and submedian line separated (shield design with median line connected with submedian lines by two transverse lines at the end of median line; admedian and submedian lines connected by two transverse lines in
P
.
kuangii
); lateral aspect of prodorsal shield smooth (short lines on lateral sides of shield in
P
.

).
