(Fig. 4)
Female (n=12). Body spindleform, yellow, 155 (150–160), 64 (59–69) wide, 41 (38–44) thick. Gnathosoma— 43 (40–46), abruptly curved downward; dorsal pedipalp genual setae (d) 5 (5–6), pedipalp coxal setae (ep) 3 (2–3), palp tarsal ventral setae (v) 4 (4–5); cheliceral stylets 47 (43–50). Prodorsal shield— 34 (33–36), 54 (50–58) wide; frontal lobe absent; shield designs three rows of cells, first 12 cells along anterolateral shield margin, second 5 cells and third 2 cells at base. Scapular tubercles and setae absent. Coxae— Sternal line present, coxae sculpted with short lines and granules; anterolateral setae on coxisternum І (1b) absent; proximal setae on coxisternum І (1a) 24 (20–29), 8 (7–8) apart; proximal setae on coxisternum І (2a) 30 (25–34), 30 (29–31) apart. Coxigenital annuli 6. Legs— Genu absent. Legs І 34 (32–35), femur 18 (17–18), basiventral femoral setae (bv) absent; tibia 4 (4–5), paraxial tibial setae (l ʹ) absent; tarsus 10 (9–10), paraxial fastigial tarsal setae (ft') 35 (31–38), antaxial fastigial tarsal setae (ft'') 38 (34–41), paraxial unguinal tarsal setae (u') 5 (5–6); tarsal empodium 8 (7–8), divided, each branch 7-rayed, tarsal solenidion 6 (6–7), knobbed. Legs І 30 (28–33), femur 15 (14–17), basiventral femoral setae (bv) absent; tibia 3 (3–4); tarsus 10 (9–10), paraxial fastigial tarsal setae (ft') 30 (28–33), antaxial fastigial tarsal setae (ft'') absent, paraxial unguinal tarsal setae (u') 5 (5–6); tarsal empodium 8 (7–8), divided, each branch 7-rayed, tarsal solenidion 6 (6–7), knobbed. Opisthosoma— Dorsum with median and admedian ridges, dorsal annuli 48 (47–50), smooth; ventral annuli 63 (62–64), with rounded microtubercles; setae c2 absent; setae d 15 (14–17), 38 (37–40) apart, on ventral annulus 21; setae e 8 (6–10), 20 (19–21) apart, on ventral annulus 38; setae f 30 (29–30), 31 (30–32) apart, on 9th ventral annulus from rear; setae h1 absent, setae h2 60 (55–65). Female genitalia— Coverflap sculpted with granules, 24 (22–25), 28 (27–30) wide, proximal setae on coxisternum ІІ (3a) 6 (6–7), 18 (17–20) apart.
Male (n=1). Body 113, 56 wide. Male genitalia— 23 wide, proximal setae on coxisternum ІІІ (3a) 6, 15 apart.
Type data. Holotype female, Tianmushan National Nature Reserve (30°22´N, 119°28´E), Lin’an county, Zhejiang Province, 20-Jul.-2007, from Lithocarpus glaber Nakai (Fagaceae), collected by Guo-Quan Wang. Paratypes 10 females and 1 male, were mounted on 11 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. camarae Mohanasundaram, 1981, but can be separated from the latter by the prodorsal shield tubercle absent and the tarsal empodium with each branch 7-rayed. In D. camarae, the prodorsal shield tubercle is present, and the tarsal empodium with each branch 6-rayed (Mohanasundaram 1981). The new species is also similar to D. euscaphiae sp. nov., but can be differentiated from the latter by the shield median line complete, setae h1 absent, and 63 ventral annuli. In D. euscaphiae sp. nov., the shield median line is incomplete, setae h1 present, and 83 ventral annuli.
