Coxae— Sternal line present, coxal area sculptured with short lines; anterolateral setae on coxisternum І (1b) 3 (2–3), 7 (5–8) apart; proximal setae on coxisternum І (1a) 10 (9–10), 10 (10–11) apart; proximal setae on coxisternum І (2a) 18 (17–20), 24 (23–25) apart. Coxi-genital annuli 2. Legs— Tibiae fused with tarsi. Leg І 25 (22–26), femur 11 (10–12), basiventral femoral setae (bv) 5 (5–6); genu 3 (2–3), antaxial genual setae (l'') 28 (25–32); tarsus 9 (8–9), paraxial fastigial tarsal setae (ft') 22 (20–25), antaxial fastigial tarsal setae (ft'') 23 (20–25), paraxial unguinal tarsal setae (u') 5 (5–6); tarsal empodium 6 (5–6), 4- rayed, tarsal solenidion 7 (6–8), knobbed. Leg І 22 (21–23), femur 10 (9–10), basiventral femoral setae (bv) 12 (10–14); genu 3 (2–3), antaxial genual setae (l'') 6 (5–6); tarsus 7 (7–8), paraxial fastigial tarsal setae (ft') 8 (7–8), antaxial fastigial tarsal setae (ft'') 25 (20–27), paraxial unguinal tarsal setae (u') 4 (3–4); tarsal empodium 5 (5–6), 4-rayed, tarsal solenidion 6 (5–6), knobbed. Opisthosoma— Dorsum with a median ridge, dorsal annuli 42 (41–42), smooth; ventral annuli 46 (45–47), with elongated microtubercles; setae c2 18 (15– 20), on ventral annulus 7th; setae d 33 (30–37), 32 (31–33) apart, on ventral annulus 16th; setae e 8 (7–10), 16 (15–17) apart, on ventral annulus 27th; setae f 15 (12–19), 18 (17–19) apart, on 7th ventral annulus from rear; setae h1 minute, 1 (1–2), setae h2 36 (30–40). Female genitalia— Coverflap smooth, 18 (17–19), 21 (20–22) wide, proximal setae on coxisternum ІІ (3a) 6 (5–6), 17 (16–17) apart.

Male (n = 6). Body fusiform, 119–132, 46–55 wide. Male genitalia 19–20 wide, proximal setae on coxisternum ІІ (3a) 8, 15 apart.

Type material. Holotype, female, from F. benjamina Linn. (Moraceae) , Menglun Town, Mengla County (21°53´N, 101°11´E), Yunnan Province, China, 3-Dec.-2007, collected by Guoquan Wang. Paratypes, 5 females and 6 males, mounted on individual slide, with the same data as holotype.

Additional material examined. 8 females and 1 male from F. t i n c t o r i a Forst. f. var. gibbosa (Moraceae) , Menglun Town, Mengla County (21°53´N, 101°11´E), Yunnan Province, China, 3–Dec.–2007, collected by Guoquan Wang; 6 females from F. v i re n s Ait. var. sublanceolata (Miq.) Corner (Moraceae) , Jianshi Forest Park, Tian’er County (25°01´N, 107°16´E), Guangxi Zhuang Autonomous Region, China, 17-Aug.-2006, collected by Guoquan Wang and Suigai Wei.

Relation to host. The mites are vagrant on the undersurfaces of the leaves, no visible damage seen.

Etymology. The specific designation is derived from the province name of the location, where the type species were collected.

Remarks. This new species is differentiated from the other three Colopodacus species ( C. begalensis Mohanasundaram, 1981 ; C. obovataus Huang & Wang, 2003 and C. virens Ou, Zhu & Wei, 2008 ) from Ficus spp., which are distributed worldwide, and Colopodacus variegatae sp. nov. by the empodium 4-rayed. The new species is similar to Colopodacus palaquius Huang, 2001 , but is separated as follows: in C. yunnanensis , empodium 4-rayed, lateral sides of prodorsal shield lines forming networks; in C. palaquius , empodium 5- rayed, lateral sides of prodorsal shield smooth ( Huang 2001a).
