(Fig. 1)
Female (n=5). Body spindleform, yellowish, 175 (153–194), 72 (69–75) wide, 57 (48–64) thick. Gnathosoma— 47 (46–48), abruptly curved downward; dorsal pedipalp genual setae (d) 8 (7–9), pedipalp coxal setae (ep) 3 (3–4), palp tarsal ventral setae (v) 5 (5–6); cheliceral stylets 54 (53–54). Prodorsal shield— 27 (26–29), 50 (48–51) wide, frontal lobe absent; median and admedian lines complete; shield designs four rows of cells, first 12 cells along anterolateral shield margin, second 8 cells, third 2 cells and fourth 2 cells at base. Scapular tubercles and setae absent. Coxae— Sternal line present, coxae sculpted with lines and granules; anterolateral setae on coxisternum І (1b) absent; proximal setae on coxisternum І (1a) 38 (35–42), 7 (7–8) apart; proximal setae on coxisternum І (2a) 60 (55–64), 28 (27–29) apart. Coxigenital annuli 6–7. Legs— Genu absent. Legs І 38 (36–40), femur 18 (17–18), basiventral femoral setae (bv) absent; tibia 6 (6–7), paraxial tibial setae (l ʹ) absent; tarsus 11 (10–12), paraxial fastigial tarsal setae (ft') 35 (31–38), antaxial fastigial tarsal setae (ft'') 34 (32–38), paraxial unguinal tarsal setae (u') 8 (7–8); tarsal empodium 11 (10–12), divided, each branch 6-rayed, tarsal solenidion 6 (6–7), knobbed. Legs І 32 (30–34), femur 14 (14–15), basiventral femoral setae (bv) absent; tibia 5 (4–5); tarsus 11 (10–12), paraxial fastigial tarsal setae (ft') 30 (28–33), antaxial fastigial tarsal setae (ft'') absent, paraxial unguinal tarsal setae (u') 7 (7–8); tarsal empodium 10 (9–11), divided, each branch 6-rayed, tarsal solenidion 6 (6–7), knobbed. Opisthosoma— Dorsum with median and admedian ridges, dorsal annuli 65 (64–67), smooth; ventral annuli 82 (81–84), with rounded microtubercles; setae c2 absent; setae d 15 (14–17), 39 (38–40) apart, on ventral annulus 30; setae e 11 (10–12), 21 (21–22) apart, on ventral annulus 52; setae f 36 (35–38), 23 (22–24) apart, on 9th ventral annulus from rear; setae h1 3 (2–3), setae h2 53 (50–55). Female genitalia— Coverflap sculpted with basal irregular short lines, 22 (18–25), 28 (25–30) wide, proximal setae on coxisternum ІІ (3a) 10 (8–11), 19 (18–20) apart.
Male (n=2). Body 158–163, 65–68 wide. Male genitalia—19 –20 wide, proximal setae on coxisternum ІІ (3a) 7–8, 13–14 apart.
Type data. Holotype female, Longtan, Tian’er County (25°01´N, 107°16´E), Guangxi Zhuang Autonomous Region, China, 17-Aug.-2006, from Ambroma augusta (Linn.) Linn. f. (Sterculiaceae), collected by Guo-Quan Wang and Sui-Gai Wei. Paratypes 4 females and 2 males, were mounted on 6 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. combreti Wei & Lu, 2001, but can be separated from the latter by the prodorsal shield with the median line complete, a row of 12 cells along anterolateral shield margin and 8 cells present in the second row from the front. In D. combreti, the prodorsal shield has the median line discontinuous, a row of 8 cells along the anterolateral shield margin and 5 cells in the second row from the front (Wei & Lu 2001).
