Legs І 35 (33–37), femur 11 (10–11), basiventral femoral setae ( bv ) 11 (10–12); genu 5 (5–6), antaxial genual setae ( l'' ) 24 (24–25); tibia 10 (9–10), paraxial tibial setae ( l' ) 4 (3–4), setae located 1/3 from dorsal base; tarsus 5 (5–6); empodium simple, 4-rayed, tarsal solenidion knobbed. Legs І 29 (27–31), femur 8 (8–9), basiventral femoral setae ( bv ) 10 (10–11); genu 4 (4–5), antaxial genual setae ( l'' ) 8 (8–9); tibia 8 (7–8); tarsus 5 (5–6); empodium simple, 4-rayed, tarsal solenidion knobbed. Opisthosoma : dorsal opisthosoma with 26 (24–29) annuli, with short-line microtubercles, ventrally with 70 (69–72) annuli, with round microtubercles. Setae c2 25 (23–26) on ventral annulus 11 (10–12); setae d 67 (65–69) on ventral annulus 26 (25–27), 31 (31–33) apart; setae e 18 (17–20) on ventral annulus 46 (45–47), 16 (16–17) apart; setae f 30 (28–31) on 5th ventral annulus from rear, 21 (20–22) apart. Setae h1 3 (3–4), setae h2 38 (36–41). Female genitalia 16 (16–17), 25 (25–26) wide, coverflap with 10 to 12 longitudinal ridges and 9 to 10 irregular lines at base, proximal setae on coxisternum ІІІ ( 3a ) 20 (19–22). MALE: Unknown. Types . Holotype , female, China : Shaanxi Province, Xi’an City, Cuihua Mountain, 34.98°N , 109.00°E . August 14, 2005 , from Actinidia sp. Lindl. ( Actinidiaceae ), coll. Xue, Xiao-Feng and Song, Zi-Wei. Paratypes , 14 females , with the same data as holotype . Relation to host. Vagrant on leaf surface. No damage to the host was observed. Etymology. The specific designation actinidiae is from the generic name of the host plant, Actinidia . Remarks. This species is similar to Tetra lucidi Xue, Song & Hong, 2006 , but can be differentiated by coxal area with granules (coxal area smooth in T . lucidi ), dorsal annuli with short-line microtubercles (dorsal annuli smooth in T . lucidi ); submedian lines separated on prodorsal shield (submedian lines connected at base on prodorsal shield in T . lucidi ).
