Prodorsal shield 43 (42–43), 56 (54–56) wide; with broad and round frontal lobe; prodorsal shield design with complete admedian lines and incomplete submedian lines, admedian lines subparallel and connect at rear; submedian lines sinuous. Scapular tubercles ahead of rear margin, 20 (20–21) apart, scapular setae (sc) 15 (14–15) projecting centrad. Coxal area with short and thick lines; anterolateral setae on coxisternum I (1b) 10 (10–12), proximal setae on coxisternum I (1a) 28 (25– 28), proximal setae on coxisternum II (2a) 35 (33–40). Prosternal apodeme present. Legs: Leg I 42 (41–42), femur 10 (10–11), basiventral femoral seta (bv) 12 (11–12); genu 6 (5–6), antaxial genual seta (l'') 35 (30–36); tibia 10 (10–11), paraxial tibial seta (l') 8 (7–8), seta located 1/2 from dorsal base; tarsus 8 (7–8), tarsal seta (u') 5 (4–5), tarsal empodium simple, 9-rayed, tarsal solenidion tapered. Leg II 38 (38–39), femur 10 (9–10), basiventral femoral seta (bv) 13 (12–14); genu 5 (4–5), antaxial genual seta (l'') 11 (9–12); tibia 8 (7–8); tarsus 7 (6–7), tarsal seta (u') 5 (4–5), tarsal empodium simple, 9-rayed, tarsal solenidion tapered. Opisthosoma: dorsal opisthosoma with 49 (49–50) annuli, with microtubercles on rear annular margins; with a broad dorsal furrow; ventrally with 57 (54–61) annuli, with elliptical microtubercles. Setae c2 28 (25–30) on ventral annulus 10 (7–11); setae d 50 (45–60) on ventral annulus 21 (19–22); setae e 32 (30–33) on ventral annulus 36 (34–36); setae f 30 (30–32) on 6th ventral annulus from rear. Setae h1 6 (5–6). Female genitalia 12 (11–13), 22 (22–23) wide, coverflap with 8–10 longitudinal ridges, proximal setae on coxisternum III (3a) 25 (25–30).
MALE: (n = 9) Body fusiform, 180 (170–190), 65 (60–65) wide, 63 (63–65) thick; light yellow. Gnathosoma 23 (22–26), projecting obliquely down, pedipalp coxal setae (ep) 4 (3–4), dorsal pedipalp genual setae (d) 10 (8–11), chelicerae 20 (19–22). Prodorsal shield 38 (36–38), 49 (47–49) wide; with broad frontal lobe. Scapular tubercles ahead of rear margin, 17 (17–19) apart, scapular setae (sc) 13 (13–14) projecting centrad. Coxal area with short lines; anterolateral setae on coxisternum I (1b) 12 (11–12), proximal setae on coxisternum I (1a) 30 (27–30), proximal setae on coxisternum II (2a) 33 (32–35). Prosternal apodeme present. Legs: Leg I 40 (38–40), femur 10 (9–10), basiventral femoral seta (bv) 10 (10–11); genu 5 (5–6), antaxial genual seta (l'') 30 (30–32); tibia 9 (9–10), paraxial tibial seta (l') 9 (7–9), seta located 1/2 from dorsal base; tarsus 8 (7–8), tarsal seta (u') 4 (4–5), tarsal empodium simple, 9-rayed, tarsal solenidion tapered.

Setae c2 30 (27–30) on ventral annulus 7 (7–8); setae d 50 (48–53) on ventral annulus 19 (18–19); setae e 30 (30–32) on ventral annulus 33 (33–35); setae f 30 (30–31) on 6th ventral annulus from rear. Setae h1 6 (6–7). Male genitalia 3 (3–4), 21 (20–22) wide, proximal setae on coxisternum III (3a) 23 (20–25).
Types. Holotype, female, from Spiraea blumei G. Don (Rosaceae), Guan’e Gou, Dangchang County, Gansu Province, China, 33°57'39N, 104°19'45E, September 12, 2005, collected by Zi-Wei Song and Xiao- Feng Xue. Paratypes, 9 females and 9 males, with the same data as holotype.
Relation to host. Mites are vagrant on the undersurface of leaves, causing no apparent damage.
Etymology. The specific designation spiraeanis is from the generic name of the host plant, Spiraea.
Remarks. This species is similar to Phyllocoptruta dimidius Huang & Wang, 2004, but can be differentiated by coxal area with short lines (coxal area I with granules, coxal area II smooth in P. dimidius), dorsal annuli with microtubercles entirely (dorsal annuli with microtubercles on lateral ridges in P. dimidius), empodium 9-rayed, tarsal solenidion tapered (empodium 6-rayed, tarsal solenidion knobbed in P. dimidius).
