Prodorsal shield 47 (45–52), 56 (55–57) wide; prodorsal shield with round frontal lobe; 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 Vshaped line, submedian lines bifurcated at 1/3 of shield from anterior. Scapular tubercles ahead of shield rear margin, 24 (20–24) apart, scapular setae (sc) 11 (8–11) projecting centrad. Coxal plates with granules and short lines; anterolateral setae on coxisternum I (1b) 10 (8–10), 15 (14–15) apart, proximal setae on coxisternum I (1a) 33 (30–33), 10 (9–10) apart, proximal setae on coxisternum II (2a) 30 (30–35), 28 (28–30) apart. Prosternal apodeme present. Legs with usual series of setae. Leg I 42 (41–44), femur 11 (10–11), basiventral femoral seta (bv) 15 (15–17); genu 6 (5–6), antaxial genual seta (l ʺ) 30 (28–30); tibia 8 (8–9), paraxial tibial seta (l ʹ) 8 (7–8), located 1/3 from dorsal base; tarsus 8 (7–8); seta ft ʹ 20 (18–22), seta ft ʺ 20 (18– 20), paraxial unguinal tarsal seta (u ʹ) 5 (5–6); tarsal empodium 8 (8–9), simple, 7-rayed, tarsal solenidion rodlike. Leg II 39 (38–40), femur 11 (10–11), basiventral femoral seta (bv) 20 (18–20); genu 5 (4–5), antaxial genual seta (l ʺ) 15 (14–15); tibia 6 (6–7); tarsus 8 (7–8); seta ft ʹ 7 (6–7), seta ft ʺ 20 (18–20), paraxial unguinal tarsal seta (u ʹ) 5 (5–6); tarsal empodium 8 (8–9), simple, 7-rayed, tarsal solenidion rod-like. Opisthosoma dorsally with 64 (60–70) annuli, with tapered microtubercles; ventrally with 79 (75–84) annuli, with tapered microtubercles laterally and round microtubercles centrally. Setae c2 25 (22–26) on ventral annulus 13 (12– 14); setae d 40 (35–40) on ventral annulus 29 (29–32), 38 (37–40) apart; setae e 25 (25–30) on ventral annulus 51 (50–58), 15 (15–16) apart; setae f 23 (23–25) on 6th ventral annulus from rear, 20 (19–20) apart. Setae h1 6 (5–6), setae h2 55 (54–60). Female genital coverflap 11 (10–11), 21 (20–22) wide, with 10 longitudinal ridges, setae 3a 50 (50–52), 17 (17–18) apart.

MALE: Unknown.

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).
