Description. FEMALE: (n = 5) Body fusiform, 190 (185–190), 61 (61–62) wide, 60 (60–61) thick; light yellow in color. Gnathosoma 20 (17–20), projecting obliquely down, pedipalp coxal seta (ep) 2 (2–3), dorsal pedipalp genual seta (d) 4 (3–4), cheliceral stylets 13 (13–14). Prodorsal shield 45 (44–45), 55 (55–56) wide; anterior shield lobe broad; admedian lines connected at center, between admedian lines with some short lines at anterior part. Scapular tubercles ahead of rear shield margin, 17 (17–18) apart, scapular setae (sc) 3 (3–4), projecting centrad. Coxal plates with few short lines, anterolateral setae on coxisternum І (1b) 6 (5–6), 10 (10–11) apart, proximal setae on coxisternum І (1a) 10 (10–12), 7 (6–7) apart, proximal setae on coxisternum І (2a) 17 (17–23), 18 (18–19) apart. Prosternal apodeme 6 (6–7). Legs with usual series of setae. Leg І 27 (27–29), femur 8 (8–9), basiventral femoral seta (bv) 7 (7–8); genu 4 (3–4), antaxial genual seta (l'') 23 (22–23); tibia 6 (5–6), paraxial tibial seta (l') 3 (3–4), located at 1/3 from proximal tibial margin; tarsus 5 (4–5), seta ft' 15 (15–16), seta ft'' 17 (15–17), seta u' 3 (2–3); tarsal empodium (em) 5 (4–5), simple, 4-rayed, tarsal solenidion (ω) 5 (4–5), knobbed. Leg І 23 (22–24), femur 7 (6–7), basiventral femoral seta (bv) 6 (6–7); genu 3 (2–3), antaxial genual seta (l'') 5 (5–6); tibia 4 (4–5); tarsus 5 (4–5), seta ft' 7 (7–8), seta ft'' 16 (15–16), seta u' 3 (2–3); tarsal empodium (em) 5 (4–5), simple, 4-rayed, tarsal solenidion (ω) 5 (4–5), knobbed. Opisthosoma: opisthosoma dorsally with 31 (30–31) annuli, with three ridges, middorsal ridge with filament microtubercles, ventrally with 72 (69–72) annuli, with round microtubercles. Setae c2 12 (10–12) on ventral annulus 7 (7–8), 46 (45–46) apart; setae d 24 (18–25) on ventral annulus 22 (22–23), 30 (30–31) apart; setae e 9 (8–9) on ventral annulus 44 (44–45), 12 (12–13) apart, setae f 15 (15–16) on 6th ventral annulus from rear, 18 (17–18) apart. Setae h1 minute, h2 32 (32–33). Female genitalia 10 (10–12), 18 (18–20) wide, coverflap with 16 to 18 longitudinal ridges, setae 3a 9 (8–9), 12 (12–13) apart.
MALE: Unknown.
Type material. Holotype, female (slide number Q16, marked Holotype), from Dioscorea persimilis Prain & Burk. (Dioscoreaceae) , Liangyuan, Danzhou City, Hainan Province, P.R. China, 19°30’50 N, 109°29’59 E, elevation 120 m, 28 September 2008, coll. Xiao-Feng Xue, Zi-Wei Song and Zhen Wang. Paratypes, 4 females (slide number Q16), with the same data as holotype.
Relation to host. Vagrant on leaf surface. No damage to the host was observed.
Etymology. The specific designation dioscoreaepersimilis is from the species name of host plant, Dioscorea persimilis .
Differential diagnosis. This species is similar to E. integrae Xue, Song & Hong, 2007 (from Salix integra ), but can be differentiated from the latter by the dorsal annuli with microtubercles only on middorsal ridge (dorsal annuli with microtubercles in E. integrae ), and admedian and submedian lines separate (admedian and submedian lines connected in E. integrae ).
