( Fig. 7 )

Description. Female (n = 30). Body fusiform, brown, 173 (108–203), 50 (46–53) wide, 49 (30–55) thick. Gnathosoma— Curved obliquely downward, 24 (22–25); dorsal pedipalp genual setae (d) 5 (5–6), pedipalp coxal setae (ep) 3 (2–3), cheliceral stylets 20 (18–22). Prodorsal shield— Frontal lobe present, 43 (41–44), 46 (42–49) wide, median and admedian lines complete, submedian lines incomplete. Scapular tubercles placed near rear shield margin, 29 (28–31) apart, scapular setae (sc) 9 (7–11), directed up. Coxae— Sternal line present, coxal area sculptured with short lines; anterolateral setae on coxisternum І (1b) 9 (8–10), 11 (10–12) apart; proximal setae on coxisternum І (1a) 17 (15–20), 9 (8–10) apart; proximal setae on coxisternum І (2a) 28 (25–30), 20 (18–23) apart. Coxi-genital annuli 2. Legs— Segments normal. Legs І 32 (29–34), femur 11 (10–12), basiventral femoral setae (bv) 8 (6–11); genu 5 (4–5), antaxial genual setae (l'') 18 (17–20); tibia 6 (6–7), paraxial tibial setae (l ʹ) located laterally at base, 2 (2–3); tarsus 8 (7–8), paraxial fastigial tarsal setae (ft') 22 (20–25), antaxial fastigial tarsal setae (ft'') 18 (15–20), paraxial unguinal tarsal setae (u') 4 (4–5); tarsal empodium 6 (5–6), 4-rayed, tarsal solenidion 7 (6–8), knobbed. Legs І 28 (26–31), femur 10 (10–11), basiventral femoral setae (bv) 14 (12–15); genu 4 (4–5), antaxial genual setae (l'') 8 (6–10); tibia 6 (5–7); tarsus 6 (5–6), paraxial fastigial tarsal setae (ft') 22 (20–23), antaxial fastigial tarsal setae (ft'') 15 (13–18), paraxial unguinal tarsal setae (u') 4 (3–4); tarsal empodium 5 (5–6), 4-rayed, tarsal solenidion 8 (7–9), knobbed. Opisthosoma— Dorsum with median and lateral ridges, dorsal annuli 26 (25–27), smooth; ventral annuli 66 (65–67), with rounded microtubercles; setae c2 13 (9–15), on ventral annulus 11th; setae d 36 (30– 40), 33 (30–38) apart, on ventral annulus 26–27th; setae e 9 (8–10), 16 (14–18) apart, on ventral annulus 41- 42nd; setae f 23 (18–28), 12 (10–15) apart, on 6th ventral annulus from rear; setae h1 minute, 1–2, setae h2 40 (35–45). Female genitalia— Coverflap sculptured with basal granules and eleven distal longitudinal ridges, 17 (16–18), 23 (20–25) wide, proximal setae on coxisternum ІІ (3a) 13 (11–14), 17 (16–19) apart.

Male (n = 1). Body fusiform, 125, 40 wide. Male genitalia 15 wide, proximal setae on coxisternum ІІ (3a) 7, 14 apart.

Type material. Holotype, female, Guangxi University campus, Nanning (22°50´N, 108°19´E), Guangxi Zhuang Autonomous Region, China, 29-Sept.-2008, from F. h i s p i d a Linn. ( Moraceae ), collected by Guoquan Wang. Paratypes, 29 females and 1 male, mounted on individual slide, 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 specific name of the type host plant.

Remarks. This new species is similar to T. buergeriani Kuang & Lin, 1993 , but they can be easily separated as follows: in T. hispidae , prodorsal shield with median, admedian and submedian lines present, ventral annuli with rounded microtubercles and female coverflap with basal granules and eleven distal longitudinal ridges; in T. buergeriani , prodorsal shield smooth, ventral annuli with elongated microtubercles and female coverflap with 14–16 distal longitudinal ridges ( Kuang & Lin 1993).
