( Fig. 4 )

Description. FEMALE: (n = 18) Body fusiform, 216 (195–216), 58 (56–58) wide, 55 (53–55) thick; light yellow. Gnathosoma 21 (20–23), projecting obliquely down, pedipalp coxal setae (ep) absent, dorsal pedipalp genual setae (d) 7 (6–7), chelicerae 19 (19–22). Prodorsal shield 43 (43–45), 50 (49–50) wide; frontal lobe present; prodorsal shield smooth. Scapular tubercles on rear margin, 42 (40–42) apart, scapular setae (sc) 10 (9–10) projecting posteriorly. Coxal area with short lines; anterolateral setae on coxisternum I (1b) 7 (6–7), proximal setae on coxisternum I (1a) 25 (25–28), proximal setae on coxisternum II (2a) 53 (50–53). Prosternal apodeme present. Legs: Leg I 42 (40–42), femur 12 (11–12), basiventral femoral seta (bv) 15 (13–15); genu 6 (5–6), antaxial genual seta (l'') 25 (23–25); tibia 7 (7–8), paraxial tibial seta (l') 10 (8–10), seta located 1/2 from dorsal base; tarsus 7 (6–7), tarsal seta (u') 5 (4–5), tarsal empodium simple, 7-rayed, tarsal solenidion rodlike. Leg II 39 (38–39), femur 11 (10–11), basiventral femoral seta (bv) 15 (15–17); genu 5 (5–6), antaxial genual seta (l'') 8 (7–8); tibia 6 (5–6); tarsus 7 (6–7), tarsal seta (u') 5 (4–5), tarsal empodium simple, 7-rayed, tarsal solenidion rodlike. Opisthosoma: dorsal opisthosoma with 19 (19–20) annuli, smooth, opisthosomal annuli separated from each other by a deep cleft; dorsal opisthosoma with lateral lobes and a middorsal ridge; ventrally with 64 (62–64) annuli, with tapered microtubercles on annular rear margin. Setae c2 45 (40–45) on ventral annulus 10 (8–10); setae d 70 (60–70) on ventral annulus 24 (21–23); setae e 23 (20–23) on ventral annulus 37 (36–37); setae f 30 (28–31) on 6th ventral annulus from rear. Setae h1 3 (2–3). Female genitalia 11 (11–12), 22 (20–22) wide, coverflap with 14 longitudinal ridges, proximal setae on coxisternum III (3a) 60 (55–60).

MALE: Not Seen.

Types. Holotype, female, from Camellia sinensis (L.) O. Ktze. ( Theaceae ), Fuzhou City, Fujian Province, China, 26°06'04N, 119°17'09E, October 27, 2005, collected by Zi-Wei Song and Xiao-Feng Xue. Paratypes, 17 females, with the same data as holotype.

Relation to host. Mites are vagrant on the undersurface of leaves, causing no apparent damage.

Etymology. The specific designation camelliae is from the generic name of the host plant, Camellia .

Remarks. This species is similar to Shevtchenkella philadelphi ( Keifer), 1961 , but can be differentiated by tarsal empodium 7-rayed and tarsal solenidion rodlike (tarsal empodium 4-rayed and tarsal solenidion knobbed in S. philadelphi ); ventral annuli with tapered microtubercles (ventral annuli with bead-like microtubercles in S. philadelphi ); accessory setae distinct, 3 long (accessory setae minute in S. philadelphi ).
