(Fig. 2)
TYPE MATERIAL. — Holotype: Jinzhong MT., 37 km SW of Longlin County (24°8’N, 105°34’E), Guangxi Zhuang Autonomous Region, China, 1.XII.2004, from Geniconthus laurifolius (Roxb.) Hook. f. (Asclepiadaceae), coll. Sui-Gai Wei, Guo-Quan Wang and De-Wei Li, ♀ (CAGU). Paratypes: same data as holotype, 10 ♀♀, 1 ơ (CAGU); 2 ♀♀ (MNHN).
ETYMOLOGY. — The specific epithet is derived from the species name of the host plant, laurifolius.
RELATION TO HOST. — The mites are vagrants on the lower surface of the leaves, no visible damage.

Female (n = 13)
Body (Fig. 2A, B) spindleform, ivory-white, 181 (171-190) long, 81 (76-85) wide, 59 (55-62) thick.
Gnathosoma 25 (24-26), projecting obliquely down, pedipalp coxal setae (ep) 2 (2-3); dorsal pedipalp genual setae (d) 7 (6-8); oryal stylets 25 (23-26).
Prodorsal shield flat, lower than dorsal opisthosoma, with a long, thick frontal lobe; 60 (57-63) long, 70 (66-73) wide; shield lines bold, median line absent, admedian lines discontinuous, submedian undulated lines complete, anterior submedian lines rhomboid-like. Scapular tubercles set ahead of rear shield margin, 20 (20- 21) apart, scapular setae (sc) 3 (3-4), directed up and mediad.
Coxae (Fig. 2C) with a sternal line, forked anteriorly and posteriorly, coxal area smooth, anterolateral setae on coxisternum I (1b) 5 (5-6), apart 15 (14-16); proximal setae on coxisternum I (1a) 10 (9-12), apart 9 (8-9); proximal setae on coxisternum II (2a) 20 (18-23), apart 27 (24-28).
Leg (Fig. 2F, G) segments normal. Leg I 29 (28- 30), femur 9 (9-10), basiventral femoral setae (bv) 6 (6-7); genu 5 (5-6), antaxial genual setae (l’’) 12 (11-13); tibia 7 (7-8), paraxial tibial setae (l’) absent; tarsus 6 (6-7), paraxial fastigial tarsal setae (ft’) 21 (19-23), antaxial fastigial tarsal setae (ft’’) 19 (17-22), paraxial unguinal tarsal setae (u’) 5 (5-6); tarsal empodium, 5 (5-6), divided, each branch 4-rayed, tarsal solenidion 6 (6-7), knobbed. Leg II 27 (26-28), femur 8 (7-9), basiventral femoral setae (bv) 7 (7-8); genu 4 (4-5), antaxial genual setae (l’’) absent; tibia 6 (6-7); tarsus 6 (6-7), paraxial fastigial tarsal setae (ft’) 20 (18-24), antaxial fastigial tarsal setae (ft’’) 6 (6-8), paraxial unguinal tarsal setae (u’) 5 (4-6); tarsal empodium, 5 (5-6), divided, each branch 4-rayed, tarsal solenidion 6 (6-7), knobbed.
Opisthosoma (Fig. 2A, B): dorsally with a broad furrow and 4 anterior projecting annuli form an arching transverse ridge, dorsum with 18 (17-19) annuli, with filamentous microtubercles except the part of the furrow; ventrally with 36 (35-38) annuli, with filamentous microtubercles; setae c2 18 (17- 20), on ventral annulus 6 (5-6), apart 63 (58-66); setae d and setae e absent; setae f 15 (14-16), on 5th ventral annulus from rear, apart 21 (19-22); setae h1 absent; setae h2 25 (22-28).
Female genitalia (Fig. 2C) 21 (20-22) long, 24 (22-25) wide, coverflap with a middle transverse suture and many longitudinal ridges, proximal setae on coxisternum III (3a) 9 (9-10), apart 18 (17-19).

Scapular tubercles set ahead of rear shield margin, 19 apart, scapular setae (sc) 3, directed up and mediad.
Coxae with a sternal line, forked anteriorly and posteriorly, coxal area smooth, anterolateral setae on coxisternum I (1b) 5, apart 13; proximal setae on coxisternum I (1a) 9, apart 8; proximal setae on coxisternum II (2a) 18, apart 24.

REMARKS
This species is similar to Protumescoptes antidesmae Pandit & Chakrabarti, 2000, but can be differentiated by female genitalia away from coxal base and tarsal empodium 4-rayed (female genitalia near coxal base and tarsal empodium 5-rayed in P. antidesmae; see Pandit & Chakrabarti, 2000).
