Leg II 42 (40–42), femur 12 (11–12), basiventral femoral seta ( bv ) 10 (8–10); genu 6 (5–6), antaxial genual seta ( l ʺ) 12 (10–12); tibia 7 (6–7); tarsus 7 (6–7); seta ft ʹ 9 (8–9), seta ft ʺ 20 (20–22), paraxial unguinal tarsal seta ( u ʹ) 5 (4–5); tarsal empodium 8 (7–8), simple, 5-rayed, tarsal solenidion knobbed. Opisthosoma: opisthosoma dorsally with 23 (21–23) annuli, anterior 19 annuli form thicken bands, with nick on some annuli; ventrally with 56 (56–59) annuli, with round microtubercles. Setae c2 20 (19–21) on ventral annulus 10 (9–11); setae d 50 (45–50) on ventral annulus 20 (20–22), 29 (29–31) apart; setae e 15 (12–15) on ventral annulus 38 (38–41), 19 (19–21) apart; setae f 26 (24– 26) on 5th ventral annulus from rear, 24 (24–25) apart. Setae h1 absent, setae h2 61 (58–62). Female genitalia coverflap 12 (10–12), 20 (19–20) wide, with 10 longitudinal ridges, setae 3a 55 (50–55), 15 (14–15) apart. MALE: Unknown. Type material. Holotype , female (slide marked NJAUAcariEri891 holotype ), from Swida macrophylla (Wall.) Sojak (Cornaceae) , Bayi Town, Nyingchi Prefecture, Tibet Autonomous Region, P. R. China (29°37΄01ʺN, 94°42΄00ʺE; H: 4247m ), 14 August , 2007, coll. Zi-Wei Song, Xiao-Feng Xue & Zhen Wang. Paratypes , 9 females (slides marked NJAUAcariEri891) with the same data as holotype . Relation to host. Vagrant on leaf undersurface. No damage to the host was observed. Etymology. The specific designation swidanus is from the host genus name “ Swida ”. Differential diagnosis. This species is similar to C. regiae Xue, Song & Hong, 2006 , but can be distinguished by prodorsal shield without median line (prodorsal shield with incomplete median line in C. regiae ); coxal plates smooth (coxal plates with short lines in C. regiae ); ventral annuli with round microtubercles (ventral annuli with spiny microtubercles in C. regiae ).
