Female (n=9). Body spindleform, white, 200 (175–231), 80 (71–89) wide, 80 (73–87) thick. Gnathosoma— 47 (43–50), abruptly curved downward; dorsal pedipalp genual setae (d) 8 (7–9), pedipalp coxal setae (ep) 5 (4–5), palp tarsal ventral setae (v) 6 (5–7); cheliceral stylets 58 (53–62). Prodorsal shield— 29 (27–30), 66 (60–72) wide; frontal lobe absent; shield designs three rows of cells, first 12 cells along anterolateral shield margin, second 5 cells and third 6 cells with 2 median cells lines immerged near the rear shield margin. Scapular tubercles and setae absent. Coxae— Sternal line present, coxae sculpted with granules; anterolateral setae on coxisternum І (1b) absent; proximal setae on coxisternum І (1a) 33 (30–35), 8 (7–9) apart; proximal setae on coxisternum І (2a) 43 (38–50), 18 (16–20) apart. Coxigenital annuli 6. Legs— Genu absent. Legs І 38 (34–41), femur 17 (15–18), basiventral femoral setae (bv) absent; tibia 5 (5–6), paraxial tibial setae (l ʹ) absent; tarsus 13 (11–14), paraxial fastigial tarsal setae (ft') 40 (36–45), with a short branch at about 1/3 from base; antaxial fastigial tarsal setae (ft'') 40 (35–45), with a short branch at about 1/3 from base; paraxial unguinal tarsal setae (u') 6 (5–7); tarsal empodium 10 (10–11), divided, each branch 7- rayed, tarsal solenidion 7 (7–8), knobbed. Legs І 29 (27–30), femur 13 (12–13), basiventral femoral setae (bv) absent; tibia 4 (3–4); tarsus 10 (10–11), paraxial fastigial tarsal setae (ft') 30 (28–34), with a short branch at about 1/3 from base; antaxial fastigial tarsal setae (ft'') absent, paraxial unguinal tarsal setae (u') 5 (5–6); tarsal empodium 10 (10–11), divided, each branch 7-rayed, tarsal solenidion 8 (7–8), knobbed. Opisthosoma —Dorsum with median and admedian ridges, dorsal annuli 59 (56–62), smooth; ventral annuli 83 (81–85), with rounded microtubercles; setae c2 absent; setae d 10 (8–13), 38 (36–40) apart, on ventral annulus 31; setae e 7 (7–8), 7 (7–8) apart, on ventral annulus 46; setae f 20 (18–25), 23 (21–25) apart, on 14th ventral annulus from rear; setae h1 2 (2–3), setae h2 58 (40–68). Female genitalia— Coverflap sculpted with granules, 22 (21–22), 27 (26–28) wide, proximal setae on coxisternum ІІ (3a) 7 (7–8), 19 (18–21) apart.
Male. Not seen.
Type data. Holotype female, Lizhou town, 24 km NE of Tianlin county (24°31'N, 106°24'E), Guangxi Zhuang Autonomous Region, China, 4-Aug.-2005, from Euscaphis japonica (Thunb.) Dipp. (Staphyleaceae), collected by De-Wei Li, Guo-Quan Wang and Sui-Gai Wei. Paratypes 8 females, were mounted on 8 slides, with the same data as holotype.
Relation to host. The mites are vagrant on the undersurfaces of the leaves, no visible damage seen.
Etymology. The specific designation is derived from the generic name of the type host plant.
Notes. The species is close to D. dendropanacis Chen, Wei & Qin, 2003, but can be separated from the latter by the prodorsal shield with a row of 12 cells along the anterolateral shield margin, and the tarsal empodium 7-rayed. In D. dendropanacis, the prodorsal shield has a row of 10 cells along the anterolateral shield margin, and the tarsal empodium is 6-rayed (Chen, Wei & Qin 2003).
