Prodorsal shield 49 (49–50), 56 (52– 59) wide; sub quadrangular; frontal lobe present; median line present 1/6 at base and connected with admedian lines, admedian and submedian lines connected at basal 1/6 and center. Dorsal tubercles ahead of rear margin, 15 (14–15) apart, scapular setae (sc) 10 (10–11) projecting centrad. Coxal area with short lines; anterolateral setae on coxisternum І (1b) 9 (7–10), proximal setae on coxisternum І (1a) 17 (16–18), proximal setae on coxisternum І (2a) 31 (30–32). Prosternal apodeme present. Legs with usual series of setae.

Gnathosoma 31–32, projecting obliquely down, pedipalp coxal setae (ep) 1–2, dorsal pedipalp genual setae (d) 5–6, chelicerae 23–24, oral stylets 20–21. Prodorsal shield 45–46, 47–49 wide; sub quadrangular; frontal lobe present. Dorsal tubercles ahead of rear margin, 13–14 apart, scapular setae (sc) 7–8 projecting centrad. Coxal area with short lines; anterolateral setae on coxisternum І (1b) 5–7, proximal setae on coxisternum І (1a) 12–13, proximal setae on coxisternum І (2a) 22–25. Prosternal apodeme present.

Types. Holotype, female, China: Shaanxi Province, Zhouzhi County, 33°53.30’N, 108°00.34’E. August 13, 2005, from Salix integra Thunb. (Salicaceae), coll. Xue, Xiao-Feng and Song, Zi-Wei. Paratypes, 3 females and 2 males, with the same data as holotype.
Relation to host. Vagrant on leaf surface. No damage to the host was observed.
Etymology. The specific designation integrae is from the specific epithet name of type host plant, integra.
Remarks. This species is similar to Epitrimerus virginiana Keifer, 1959, but can be differentiated by female genital coverflap with 10 to 12 longitudinal ridges (female genital coverflap with 14 longitudinal ridges in E. virginiana), admedian and submedian lines connected at center (admedian and submedian lines connected at center and basal 3/ 4 in E. virginiana).
