Leg І 30 (30–32), femur 8 (8–9), basiventral femoral seta (bv) 19 (18–19); genu 5 (4–5), antaxial genual seta (l ') 16 (12–16); tibia 5 (4–5); tarsus 9 (9–10), seta ft ' 8 (7–8), seta ft ' 32 (28–32), seta u ' 8 (7–8); tarsal empodium (em) 12 (11–12), simple, 6-rayed, tarsal solenidion (ω) 14 (14–15), rod-like. Opisthosoma: opisthosoma dorsally with 54 (54–58) annuli, with spiny microtubercles projecting ahead of rear annular margins, ventrally with 60 (57–60) annuli, with spiny microtubercles projecting ahead of rear annular margins. Setae c2 28 (26–28) on ventral annulus 8 (8–9), 62 (62–63) apart; setae d 71 (62–71) on ventral annulus 22 (19–22), 50 (48–50) apart; setae e 20 (15–20) on ventral annulus 39 (37–39), 32 (32–33) apart, setae f 19 (17–19) on 5–6th ventral annulus from rear, 17 (17–19) apart.

MALE: Unknown.  
 Type material. Holotype , female (slide number NJAUAcariEri421, marked Holotype), from Carya cathayensis Sarg. (Juglandaceae), Cuihua Mountain, Xi' an City, Shaanxi Province, P. R. China, 34°59'40' N, 109°00'04' E, elevation 901m, 15 August 2005, coll. Xiao-Feng Xue & Zi-Wei Song. Paratypes, 7 females (slide number NJAUAcariEri421), with the same data as holotype.   
 Relation to host. Vagrant on leaf surface. No damage to the host was observed.   
 Etymology. The specific designation cathayensis is from the species name of the host plant, cathayensis.   
 Differential diagnosis. This species is similar to Proartacris taiwanensis Huang, 2001, but can be differentiated from the latter by the prodorsal shield with median line present, admedian and submedian lines connected (median line absent, admedian and submedian lines separated in Proartacris taiwanensis), dorsal and ventral annuli with spiny microtubercles projecting ahead of rear annular margins (dorsal and ventral annuli on rear annular margins in Proartacris. taiwanensis), and coxal plates with short lines (coxal plates with granules in Proartacris taiwanensis).
