Description. Female (n =10). Body fusiform, yellowish, 145 (118–194), 58 (39–63) wide.

Gnathosoma. Curved obliquely downward, 23 (20–24); dorsal pedipalp genual setae (d) 7 (6–11), pedipalp coxal setae (ep) 3 (3–4), cheliceral stylets 19 (19–25).

Prodorsal shield. 43 (40–46), 40 (38–46) wide, frontal lobe 10 (9–11), shield design with median line from base to basal 1/3, admedian lines complete, median line and admedian lines connected by two trasverse lines at basal 1/3 and 1/6, and submedian lines connected to admedian lines in distal 1/3 of shield, submidian lines connected at base. Scapular tubercles near rear margin, 38 (30–38) apart, scapular setae (sc) 9 (9–10), directed backward and divergently.

Coxae. Prosternal apodeme present, coxal area smooth; anterolateral setae on coxisternum І (1b) 5 (3–8), 12 (11–12) apart; proximal setae on coxisternum І (1a) 14 (8–15), 8 (7–8) apart; proximal setae on coxisternum ІІ (2a) 28 (15–33), 22(21–24) apart. Coxi-genital annuli 4–6.

Legs. Segments normal. Leg I 30 (29–33), femur 8 (8–9), basiventral femoral setae (bv) 8 (6–10); genu 5 (5–6), antaxial genual setae (l'') 18 (15–20); tibia 8(8–9), paraxial tibial setae (l') located at center, 3 (2–3); tarsus 6 (5–6), paraxial fastigial tarsal setae (ft') 10 (10–13), antaxial fastigial tarsal setae (ft'') 20 (15–23), paraxial unguinal tarsal setae (u') 3 (2–3); tarsal empodium 4 (4–5), 4-rayed, tarsal solenidion 5 (5–6), knobbed. Leg II 27 (27–32), femur 8 (8–9), basiventral femoral seta (bv) 7 (6–7); genu 4 (4–5), antaxial genual setae (l'') 6 (6–8); tibia 7 (7–8); tarsus 5 (5–6), paraxial fastigial tarsal setae (ft') 5 (5–8), antaxial fastigial tarsal setae (ft'') 18 (15–20), paraxial unguinal tarsal setae (u') 3 (2–3); tarsal empodium 4 (4–5), 4-rayed, tarsal solenidion 5 (5–6), knobbed.

Opisthosoma. Dorsum with a wide middorsal longitudinal furrow and two lateral ridges; dorsal annuli 32 (31–33), smooth; ventral annuli 63 (61–65), with rounded microtubercles; setae c2 18 (15–20), on ventral annulus 13th; setae d 38 (28–55), 30 (30–32) apart, on ventral annulus 31th; setae e 16 (15–18), 18 (18–19) apart, on ventral annulus 48th; setae f 20 (19–25), 23 (23–24) apart, on 6th ventral annulus from rear; setae h1 3 (3–4), setae h2 51 (45–58).

Female genitalia. Coverflap with 12–14 longitudinal ridges, 15 (12–16), 20 (18–23) wide, setae (3a) 10 (10–13), 13 (12–13) apart.

Male. Unkonwn.

Material examined. Holotype female, Xincheng County (24°0′N, 108°36′E), Guangxi Zhuang Autonomous Region, China, 20 May 2011, from Zanthoxylum armatum DC. var. armatum   ( Rutaceae   ), coll. Shan-Sheng Ou and Sui-Gai Wei. GoogleMaps   Paratypes 9 females, mounted on individual slide, same data as holotype.  

Biology. The mites are free-living on the undersurface of leaves, no conspicuous damage was observed.

Etymology. This species is named after the specific name of the type host plant.

Remarks. This new species is similar to T. lucidi Xue   , Song & Hong, 2006, but can be diagnosed by: admedian lines complete, median line and admedian lines connected by two trasverse lines at basal 1/3 and 1/6, female coverflap without transverse lines at base. In T. lucidi   , the prodorsal shield median line separate from admedian lines, female coverflap with two transverse lines at base (Xue, Song & Hong, 2006).
