Gnathosoma 22 (20–22), projecting obliquely down, pedipalp coxal seta (ep) 5 (4–5), dorsal pedipalp genual seta (d) 7 (6–7), cheliceral stylets 16 (15–16). Prodorsal shield triangular, 48 (48–50), 61 (57–62) wide; prodorsal shield with round frontal lobe; shield design with median line absent, admedian and submedian lines incomplete and subparallel. Scapular tubercles ahead of shield rear margin, 22 (22–23) apart, scapular setae (sc) 10 (9–11) projecting centrad. Coxal plates with granules; anterolateral setae on coxisternum I (1b) 10 (8–10), 13 (12–13) apart, proximal setae on coxisternum I (1a) 25 (22–25), 10 (9–11) apart, proximal setae on coxisternum II (2a) 40 (40–43), 32 (30–32) apart. Prosternal apodeme present. Legs with usual series of setae. Leg I 46 (44–46), femur 13 (12–13), basiventral femoral seta (bv) 10 (10–11); genu 6 (5–6), antaxial genual seta (l ʺ) 23 (23–25); tibia 10 (9–10), paraxial tibial seta (l ʹ) 6 (6–7), located 1/3 from dorsal base; tarsus 7 (7–8); seta ft ʹ 14 (14–16), seta ft ʺ 15 (13–15), paraxial unguinal tarsal seta (u ʹ) 7 (6–7); tarsal empodium 7 (6–7), simple, 7-rayed, tarsal solenidion knobbed. Leg II 42 (41–42), femur 12 (11–12), basiventral femoral seta (bv) 10 (8–10); genu 6 (5–6), antaxial genual seta (l ʺ) 10 (9–10); tibia 8 (7–8); tarsus 7 (7–8); seta ft ʹ 5 (5–6), seta ft ʺ 15 (13–15), paraxial unguinal tarsal seta (u ʹ) 6 (6–7); tarsal empodium 7 (6–7), simple, 7-rayed, tarsal solenidion knobbed. Opisthosoma dorsally with 49 (45–49) annuli, smooth; ventrally with 62 (59–62) annuli, with round microtubercles. Setae c2 31 (28–31) on ventral annulus 11 (11–13); setae d 40 (40–46) on ventral annulus 22 (22–23), 33 (33–36) apart; setae e 35 (35–38) on ventral annulus 40 (38– 40), 14 (14–15) apart; setae f 25 (22–25) on 6th ventral annulus from rear, 28 (25–28) apart. Setae h1 5 (4–5), setae h2 85 (80–85). Female genital coverflap 14 (14–15), 24 (22–24) wide, with 12–14 longitudinal ridges, setae 3a 30 (30–32), 17 (17–18) apart.
MALE: Unknown.
Type material. Holotype, female (slide marked NJAUAcariEri927 holotype), from Spiraea myrtilloides Rehd. (Rosaceae), 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 NJAUAcariEri927) with the same data as holotype.
Relation to host. Vagrant on leaf undersurface. No damage to the host was observed.
Etymology. The specific designation bayisis is from the name of the location, “Bayi Town” where the species were found.
Differential diagnosis. This species is similar to P. japonicae Song, Xue & Hong, 2006, but can be differentiated by the coxal plates with granules (coxal plates smooth in P. japonicae); tarsal empodium 7- rayed, solenidion knobbed (tarsal empodium 6-rayed, solenidion tapered in P. japonicae); female genital coverflap with 12–14 longitudinal ridges (female genital coverflap with 8 longitudinal ridges in P. japonicae).
