Scapular tubercles set ahead of rear shield margin, 21 (20–25) apart, scapular setae (sc) 7 (6–8), directed upwards.
Coxae. Coxae I separated, coxal area with short lines; anterolateral setae on coxisternum І (1b) 6 (5–6), 10 (10–13) apart; proximal setae on coxisternum І (1a) 10 (9–12), 9 (9–12) apart; proximal setae on coxisternum ІІ (2a) 21 (20–25), 20 (19–26) apart. Coxi-genital annuli 4–5.
Legs. Segments normal. Leg I 31 (28–33), femur 11 (10–11), basiventral femoral setae (bv) 8 (8–9); genu 4 (4–5), antaxial genual setae (l'') 25 (22–27); tibia 8 (7–8), paraxial tibial setae (l') located 1/3 from dorsal base, 4 (3–5); tarsus 5 (4–6), paraxial fastigial tarsal setae (ft') 17 (15–18), antaxial fastigial tarsal setae (ft'') 18 (17–25), paraxial unguinal tarsal setae (u') 4 (3–4); tarsal empodium divided, each empodial branch four-rayed, 4 (4–5), tarsal solenidion 5 (5–6), knobbed.

Material examined. Holotype female, Xincheng County (24°0′N, 108°36′E), Guangxi Zhuang Autonomous Region, China, 21 May 2011, from Rubus lambertiannus Ser. (Rosaceae), coll. Shan-Sheng Ou and Sui-Gai Wei. Paratypes 7 females and 2 males, mounted on individual slide, same data as holotype.
Biology. The mites are free-living on the undersurface of leaves, no conspicuous damage was observed.
Etymology. This species is named after the specific name of the type host plant.
Remarks. This new species is similar to P. taiwannensis, Huang, 2001, but can be diagnosed by: shield design without median line, admedian lines forming trapezoid and rectangular; dorsal annuli ridges smooth; submedian lines incomplete; coxae I separated, coxal area with short lines; empodium divided, 4-rayed. In P. taiwannensis, the shield pentagonal, with projection at lateral and posterolateral areas, shield design with median line, admedian lines complete, submedian line absent; ridges with spiny microtubercles, coxal area smooth; fore coxal prosternal apodeme absent, empodium divided, 6-rayed (Huang, 2001b)
