Leg ІІ 31 (29–34), trochanter 2 (2), femur 11 (10–11), femoral setae (bv) absent; genu 4 (3–4), genual setae (l'') 8 (7–10); tibia 6 (6); tarsus 6 (6–7), inner fastigial tarsal setae (ft') 20 (20), outer fastigial tarsal setae (ft'') 6 (5–8), unguinal tarsal setae (u') 4 (3–4); tarsal empodium entire, 7 (7–8), 4-rayed, tarsal solenidion 8 (8–9), knobbed.
Opisthosoma. Dorsum with median and admedian ridges, dorsal annuli 33 (33), smooth; ventral annuli 62 (62), with rounded microtubercles; setae c2 15 (15), on ventral annulus 14th; setae d 30 (30), 27 (25–28) apart, on ventral annulus 27th; setae e 15 (15), 10 (10–11) apart, on ventral annulus 39th; setae f 20 (20), 18 (15–21) apart, on 6th ventral annulus from rear; setae h1 absent, setae h2 51 (45–55).
Female genitalia. Coverflap with distal longitudinal ridges, 10 (10), 19 (19) wide, proximal setae on coxisternum ІІІ (3a) 13 (13), 11 (10–12) apart.
Male (n = 2). Same as female, body fusiform, 123, 51 wide; male genital 15 wide, proximal setae on coxisternum ІІІ (3a) 11, 9 apart.
Holotype female, Fengyangshan National Nature Reserve (27°53´N, 119°11´E), Longquan City, Zhejiang, China, 28 July 2007, leg. Guo-Quan Wang, from Schima superba Gardn. & Champ (Theaceae). Paratypes 4 females and 2 males, same data as holotype.
Relation to host. The mites are vagrants on the undersurfaces of the leaves, with no visible damage.
Distribution. China (Zhejiang).
Etymology. The specific designation is derived from the generic name of the type host plant, gender feminine.
Remarks. The new species is similar to L. lysimachiae Hong & Kuang, 1989, but can be distinguished from the latter by the complete prodorsal shield median line, absent submedian lines, and absent setae h1. In L. lysimachiae, the median and submedian lines are incomplete and setae h1 is present (Hong & Kuang, 1989).
