Prodorsal shield 38 (37–38), 35 (34–37) wide; subtriangular; frontal lobe acuminate; median line present 1/3 at base and connected with admedian lines at basal 1/3 and base, admedian and submedian lines connected by a transverse line; median, admedian and submedian lines connected and form four cell at base and three cell at middle, there are granules on lines. Dorsal tubercles on rear margin, 26 (24–27) apart, scapular setae (sc) 25 (23–27) projecting posterior. Coxal area with granules; anterolateral setae on coxisternum (1b) 8 (6–9), proximal setae on coxisternum (1a) 15 (14– 16), proximal setae on coxisternum (2a) 29 (28–31). Prosternal apodeme present. Legs with usual series of setae. Legs 29 (28–31), femur 8 (8–9), basiventral femoral setae (bv) 10 (9–12); genu 5 (5–6), antaxial genual setae (l'') 20 (18–21); tibia 7 (7–8), paraxial tibial setae (l') 8 (8–9), setae located 1/3 from dorsal base; tarsus 5 (5–6); empodium simple, 7­rayed, rodlike solenidion. Legs 26 (25–28), femur 7 (7–8), basiventral femoral setae (bv) 8 (7–10); genu 4 (4–5), antaxial genual setae (l'') 8 (8–9); tibia 7 (6–7); tarsus 5 (5–6); empodium simple, 7­rayed, rodlike solenidion. Opisthosoma: dorsal opisthosoma with 44 (41–50) annuli, with rounded microtubercles, ventrally with 64 (61–67) annuli, with rounded microtubercles. Setae c2 20 (18– 23) on ventral annulus 12 (11–12); setae d 55 (49–57) on ventral annulus 26 (24–27); setae e 35 (33–36) on ventral annulus 44 (43–45), setae f 28 (29–31) on 6th ventral annulus from rear. Setae h1 4 (3–4). Female genitalia 12 (12–13), 19 (18–20) wide, coverflap with 10 longitudinal ridges, proximal setae on coxisternum

(3a) 18 (17–20).

MALE: (n = 1) 162, 45 wide; genitalia 4, 27 wide, proximal setae on coxisternum III (3a) 12.

Types. Holotype, female, China: Shaanxi Province, Foping County, 33°30.48’N, 107°58.52’E. September 4, 2004, from Salix sp. L. ( Salicaceae ), coll. Xue, Xiao­Feng and Song, Zi­Wei. Paratypes, 9 females and 1 male, with the same data as holotype.

Relation to host. Vagrant on leaf surface. No damage to the host was observed.

Etymology. The specific designation salixis is from the generic name of the type host plant, Salix .

Remarks. This species is similar to Aculops rhodensis ( Keifer), 1957 , but can be differentiated by coxal area with granules (coxal area with short lines in A. rhodensis ), female genital coverflap with 10 longitudinal ridges (female genital coverflap with 14 longitudinal ridges in A. rhodensis ) and different prodorsal shield designs.
