Legs 27 (26–29), femur 8 (7–9), basiventral femoral setae (bv) 10 (10–11); genu 4 (3–4), antaxial genual setae (l'') 6 (5–7); tibia 5 (5–6); tarsus 6 (5–6); tarsal empodium simple, 5­rayed, tarsal solenidion knobbed. Opisthosoma: dorsal opisthosoma with 13 (12–14) annuli, with filamentous microtubercles on rear annular margins, ventrally with 60 (58–61) annuli, with spiny microtubercules on rear annular margins. Setae c2 11 (10–12) on ventral annulus 8 (8–9); setae d 49 (47–53) on ventral annulus 20 (19–21); setae e 15 (13–16) on ventral annulus 35 (33–36), setae f 13 (12–15) on 5th ventral annulus from rear. Setae h1 2 (2–3). Female genitalia 12 (12–13) long, 25 (24–26) wide, coverflap with 8 longitudinal ridges and 2 discontinuous transverse lines at base, proximal setae on coxisternum (3a) 14 (12–15).

Types

Holotype, female, China: Shaanxi Province, Yang County, Huanyang, 33°35.23’N, 107°32.26’E. August 8, 2005, from Juglans regia L. ( Juglandaceae ), coll. Xue, Xiao­Feng & Song, Zi­Wei. Paratypes, 8 females and 1 male, with the same data as holotype.
