Type
material.
Holotype
, female (slide marked NJAUAcariEri905
holotype
), from
Lonicera stephanocarpa
Franch. (Caprifoliaceae)
, Bayi Town, Nyingchi (Linzhi) Prefecture, Tibet Autonomous Region, P. R.
China
,
14 August
, 2007, coll. Zi-Wei Song, Xiao-Feng Xue & Zhen Wang.
Paratypes
,
7 females
(slides marked NJAUAcariEri905) with the same data as
holotype
.
Relation to host.
Vagrant on leaf undersurface. No damage to the host was observed.
Etymology.
The specific designation
stephanocarpae
is from the host species name “
stephanocarpa
”.
Differential diagnosis.
This species is similar to
P. solanumi
Kuang, 2000
, but can be differentiated by the prodorsal shield design with median and submedian lines incomplete, admedian lines complete, median and admedian lines connected at 1/4 of shield from posterior with a V-shaped line, submedian lines bifurcated at 1/3 of shield from anterior (median and submedian lines incomplete, admedian lines complete and sinuous, all lines not connected with each other in
P. solanumi
); coxal plates with granules and short lines (coxal plates with only short lines in
P. solanumi
); tarsal empodium 7-rayed (tarsal empodium 5-rayed in
P. s o l a n u m i
).
