Prodorsal shield 45 (45–47), 57 (55–57) wide; prodorsal shield with round frontal lobe; shield design with median and submedian lines incomplete, median line only present 1/3 of the shield at posterior, admedian lines complete and sinuous. Scapular tubercles ahead of shield rear margin, 20 (20–22) apart, scapular setae (sc) 10 (9–11) projecting centrad. Coxal plates with granules; anterolateral setae on coxisternum I (1b) 10 (7–10), 14 (13–14) apart, proximal setae on coxisternum I (1a) 20 (20–22), 10 (9–11) apart, proximal setae on coxisternum II (2a) 30 (30–35), 27 (27–29) apart. Prosternal apodeme absent. Legs with usual series of setae. Leg I 42 (40–42), femur 12 (11–12), basiventral femoral seta (bv) 12 (12–13); genu 6 (5–6), antaxial genual seta (l ʺ) 25 (23–25); tibia 8 (7–8), paraxial tibial seta (l ʹ) 8 (7–8), located 1/3 from dorsal base; tarsus 7 (6–7); seta ft ʹ 20 (20–22), seta ft ʺ 18 (18– 20), paraxial unguinal tarsal seta (u ʹ) 5 (4–5); tarsal empodium 8 (7–8), simple, 7-rayed, tarsal solenidion knobbed. Leg II 39 (37–39), femur 11 (10–11), basiventral femoral seta (bv) 15 (15–17); genu 5 (4–5), antaxial genual seta (l ʺ) 10 (10–11); tibia 6 (5–6); tarsus 7 (6–7); seta ft ʹ 8 (7–8), seta ft ʺ 18 (18–20), paraxial unguinal tarsal seta (u ʹ) 5 (4–5); tarsal empodium 8 (7–8), simple, 7-rayed, tarsal solenidion knobbed. Opisthosoma dorsally with 45 (45–50) annuli, with round microtubercles; ventrally with 72 (70–75) annuli, with round microtubercles. Setae c2 30 (30–40) on ventral annulus 13 (12–13); setae d 60 (50–60) on ventral annulus 28 (28–29), 37 (35–37) apart; setae e 35 (35–38) on ventral annulus 50 (50–52), 16 (14–16) apart; setae f 30 (28–30) on 6th ventral annulus from rear, 26 (26–27) apart. Setae h1 4 (3–4), setae h2 61 (58–62). Female genital coverflap 11 (10–11), 20 (19–20) wide, with 10–12 longitudinal ridges, setae 3a 30 (28–30), 17 (16–17) apart.
MALE: Unknown.
Type material. Holotype, female (slide marked NJAUAcariEri923 holotype), from Lonicera webbiana Wall. ex DC. (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 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).
