(Fig. 1)

Description. FEMALE: (n = 8) Body fusiform, 204 (191–210), 48 (46–49) wide, 55 (53–57) thick; light yellow. Gnathosoma 18 (17–19), projecting obliquely down, pedipalp coxal setae (ep) 3 (2–3), dorsal pedipalp genual setae (d) 5 (4–6), chelicerae 17 (16–18). Prodorsal shield 39 (38–40), 36 (35–38) wide; frontal lobe present; prodorsal shield design with admedian lines indistinct, median line and submedian lines absent, with granules at lateral margins. Scapular tubercles on rear margin, 22 (21–23) apart, scapular setae (sc) 7 (6–9) projecting posteriorly. Coxal area with short lines; anterolateral setae on coxisternum I (1b) 6 (6–7), proximal setae on coxisternum I (1a) 21 (19–22), proximal setae on coxisternum II (2a) 34 (29–38). Prosternal apodeme present. Legs: Leg I 31 (29–33), femur 9 (8–9), basiventral femoral seta (bv) 12 (10–14); genu 5 (5–6), antaxial genual seta (l'') 17 (15–19); tibia 8 (8–9), paraxial tibial seta (l') 5 (5–6), seta located 1/3 from dorsal base; tarsus 5 (5–6), tarsal empodium simple, 6-rayed, tarsal solenidion knobbed. Leg II 25 (24–27), femur 7 (7–8), basiventral femoral seta (bv) 8 (8–9); genu 4 (4–5), antaxial genual seta (l'') 6 (6–7); tibia 5 (4–5); tarsus 5 (5–6), tarsal empodium simple, 6-rayed, tarsal solenidion knobbed. Opisthosoma: dorsal opisthosoma with 64 (57–66) smooth annuli, dorsal opisthosoma with three ridges, middorsal ridge shorter than subdorsal ridges and ending in a dorsal furrow; ventrally with 71 (68–73) annuli, with round microtubercles on rear annular margin. Setae c2 10 (9–11) on ventral annulus 10 (8–12); setae d 27 (25–30) on ventral annulus 28 (26–30); setae e 16 (13–19) on ventral annulus 49 (47–51); setae f 26 (21–29) on 7th ventral annulus from rear. Setae h1 2 (2–3). Female genitalia 10 (10–11), 19 (18–20) wide, coverflap with 10 longitudinal ridges and two cross lines at base, proximal setae on coxisternum III (3a) 15 (14–16).

MALE: Unknown.

Types. Holotype, female, from Rhus chinensis Mill. (Anacardiaceae) , Foping County, Shaanxi Province, China, 33°30'N, 107°58'E, September 4, 2004, coll. by Xiao-Feng Xue and Zi-Wei Song. Paratypes, 7 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 fopingi is from the locality where the host plant and the new species were collected, Foping County.

Remarks. This species is similar to A. phalaris Kuang, 1997 , but can be differentiated by female genital coverflap with two cross lines at base (female genital coverflap smooth at base in A. phalaris ); empodium 6- rayed, tarsal solenidion knobbed (empodium 7 to 8-rayed, tarsal solenidion rodlike in A. phalaris ); paraxial tibial seta (l') located 1/3 from dorsal base (paraxial tibial seta (l') located 1/2 from dorsal base in A. phalaris ).
