Description. FEMALE: (n = 10) Body fusiform, 175 (150–184), 66 (64–69) wide, 64 (57–75) thick; light yellow. Gnathosoma 19 (15–21), projecting obliquely down, pedipalp coxal setae (ep) 4 (4–5), dorsal pedipalp genual setae (d) 8 (7–8), chelicerae 17 (13–19). Prodorsal shield 48 (45–50), 55 (54–55) wide; with frontal lobe broad and round; prodorsal shield design with incomplete median and submedian lines, complete admedian lines; admedian lines sinuous at 1/4 anterior and connected with median line at 1/2 forming a diamondshaped cell; admedian lines connected with median line at the end forming an arrow shaped cell; the inner submedian lines connected with each other forming an “X” shape mark, the outer submedian lines sinuous at 1/2. Scapular tubercles lightly ahead of rear margin, 22 (20–25) apart, scapular setae (sc) 8 (7–10) projecting centrad. Coxal area with short lines; anterolateral setae on coxisternum I (1b) 8 (7–8), proximal setae on coxisternum I (1a) 27 (25–30), proximal setae on coxisternum II (2a) 42 (40–45). Prosternal apodeme present. Legs: Leg I 40 (40–41), femur 11 (11–12), basiventral femoral seta (bv) 12 (11–13); genu 5 (5–6), antaxial genual seta (l'') 24 (24–25); tibia 8 (7–9), paraxial tibial seta (l') 10 (9–10), seta located at base; tarsus 6 (6–7), tarsal seta (u') 4 (4–5), tarsal empodium divided, each 2-rayed, tarsal solenidion knobbed. Leg II 38 (38–40), femur 10 (9–10), basiventral femoral seta (bv) 10 (9–10); genu 5 (5–6), antaxial genual seta (l'') 6 (6–7); tibia 7 (6–7); tarsus 6 (6–7), tarsal seta (u') 4 (4–5), tarsal empodium divided, each 2-rayed, tarsal solenidion knobbed. Opisthosoma: dorsal opisthosoma with 47 (45–47) annuli smooth, dorsal opisthosoma with a narrow middorsal ridge, ventrally with 60 (59–60) microtuberculate annuli. Setae c2 30 (28–32) on ventral annulus 13 (12–13); setae d 52 (52–53) on ventral annulus 28 (28–30); setae e 20 (20–23) on ventral annulus 46 (45–48); setae f 22 (20–25) on 6th ventral annulus from rear. Setae h1 absent. Female genitalia 19 (18–20), 23 (23–24) wide, coverflap with 10–12 longitudinal ridges, proximal setae on coxisternum III (3a) 56 (53– 60).
MALE: Unknown.
Types. Holotype, female, from Salix sp. (Salicaceae), Guan’e Gou, Dangchang County, Gansu Province, China, 33°57'39N, 104°19'45E, September 11, 2005, collected by Zi-Wei Song and Xiao-Feng Xue. Paratypes, 9 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 adamantis is from the diamond shape pattern of the prodorsal shield.
Remarks. This species is similar to Acaphyllisa cryptomeria Huang, 2001, but can be differentiated by dorsal annuli smooth (dorsal annuli with spiny microtubercles in A. cryptomeria); coxal area with short lines (coxal area smooth in A. cryptomeria); setae h1 absent (setae h1 present in A. cryptomeria).
