Legs ІІ 35 (34–38), femur 12 (12–13), basiventral femoral setae ( bv ) absent; genu 4 (4–5), antaxial genual setae ( l'' ) 11 (10–11); tibia 9 (8–9); tarsus 8 (8–9), paraxial fastigial tarsal setae ( ft' ) 35 (34–38), antaxial fastigial tarsal setae ( ft'' ) 15 (12–17), paraxial unguinal tarsal setae ( u' ) 7 (7–8); tarsal empodium 8 (8–9), divided, each branch 5-rayed, tarsal solenidion 8 (7–8). Opisthosoma— A slight dorsal median ridge present; dorsal annuli 63, smooth; ventral annuli 80, with rounded microtubercles; setae c2 35 (30–38), on ventral annulus 17; setae d 80 (75–85), 53 (51–54) apart, on ventral annulus 32; setae e 76 (60–70), 25 (25–26) apart, on ventral annulus 52; setae f 38 (35–42), 30 (29–31) apart, on 9th ventral annulus from rear; setae h1 1, setae h2 150 (132–156). Female genitalia— Coverflap smooth, 30 (30–31), 35 (35–36) wide, proximal setae on coxisternum ІІІ ( 3a ) 10 (10–11), 22 (21–23) apart. FIGURE 2. Diptacus daphniphyllus sp. nov. CGF—coxigenital area of female; D—dorsal view of female; E—empodium; L1—Legs І; L2—Legs І; LS—lateral view of annuli (enlarged) (Scale bar: CGF—57; D—74; E—18; L1, L2—29). Male. Not seen. Type data. Holotype , female, Fengyangshan National Nature Reserve ( 27°53´N , 119°11´E , altitude 1550m ), Longquan City, Zhejiang Province, China , 28–Jul.–2007 , from Daphniphyllum macropodum Miq. (Daphniphyllaceae), collected by Guoquan Wang. Paratypes , 7 females , mounted on 7 slides, with the same data as holotype . Relation to host. The mites are vagrant on the undersurfaces of the leaves, no visible damage. Etymology. The specific designation is derived from the generic name of the type host plant. Notes. This new species is similar to Diptacus tristylaus Huang 2001 , but can be differentiated by the prodorsal shield with median and admedian lines complete, the coxal area with granules, the tarsal empodium with each branch 5-rayed, female genital coverflap smooth. In D. tristylaus , the prodorsal shield and the coxal area smooth, the female genital coverflap with ridges and the tarsal empodium with each branch 8-rayed ( Huang, 2001 ).
