Scapular tubercles set on rear shield margin, 40 (38–40) apart. Scapular setae (sc) 9 (8–10) long, directed backward. Coxae with a sternal line; coxae smooth; 1st coxal seta (1b) 6 (6–7) long, 2nd coxal seta (1a) 10 (9–10) long, 3rd coxal seta (2a) 21 (19–21) long. Leg segments normal. Leg I 28 (27–30) long, femur 8 (8–9) long, femoral seta (bv) 5 (5–6) long, genu 5 (4–5) long, genual seta (l´´) 20 (18–22) long, tibia 7 (6–7) long, tibial seta (l') 4 (4–5) long, set at half, tarsus 5 (5–6) long, empodium simple, 4­rayed, solenidion ending as knob. Leg II 27 (26–28) long, femur 8 (8–9) long, femoral seta 11 (10–11) long, genu 4 (4–5) long, genual seta absent, tibia 6 (5–6) long, tarsus 5 (5–6) long. Opisthosoma with middorsal ridge and lateral ridges, median ridge ending before lateral ridges; dorsum with 30 (28–31) annuli, smooth; ventrally with 79 (77–80) annuli, with rounded microtubercles. Lateral seta (c2) 17 (15–20) long, on ventral annulus 18 (17–18); 1st ventral seta (d) 40 (37–42) long, on ventral annulus 21 (20–22); 2nd ventral seta (e) 15 (14–16) long, on ventral annulus 43 (42–44); 3rd ventral seta (f) 20 (18–21) long, on 6th ventral annulus from rear; accessory seta (h1) absent. Female genitalia 16 (15–16) long, 21 (20–23) wide, genital coverflap with 2 ranks of longitudinal ridges, genital seta (3a) 7 (6–7) long.

Male: Body 172 long, 69 wide, genitalia 18 wide, genital seta (3a) 5 long.

Type data: Holotype, female, Jinzhong MT., 37 km SW of Longlin County (24°8 ' N, 105°34 ' E), Guangxi Zhuang Autonomous Region, China, 01­Dec.­2004, from Maesa japonica (Thunb.) Moritzi and Zll. (Myrsinaceae) , coll. Sui­gai WEI, Guo­quan WANG and De­wei LI. Paratypes, 20 females and 2 males, with the same data as Holotype.

Relation to host: The mites are vagrants on the under surface of the leaves.

Etymology: The specific designation is derived from the specific designation of the type host plant.
