Legs ІІ 32 (29–35), trochanter 2 (2), femur 13 (11–14), basiventral femoral setae ( bv ) 7 (6–8); genu 4 (4–5), antaxial genual setae ( l'' ) 12 (10–14); tibia 5 (4–5); tarsus 8 (8–9), paraxial fastigial tarsal setae ( ft' ) 32 (25–38), antaxial fastigial tarsal setae ( ft'' ) 13 (12–13), paraxial unguinal tarsal setae ( u' ) 5 (4–5); tarsal empodium (ω) entire, 9 (8–11), 8-rayed, tarsal solenidion 10 (10–11), knobbed. Opisthosoma— Dorsum evenly rounded, dorsal annuli 70 (68–72), with rounded microtubercles, projecting posteriad from the rear annular margin; ventral annuli 88 (87–90), with rounded microtubercles on rear annular margin; setae c2 8 (7–8), on 18th ventral annulus; setae d 51 (45–55), 31 (30–33) apart, on 27th or 28th ventral annulus; setae e 33 (30–35), 25 (22–28) apart, on 45th or 46th ventral annulus; setae f 31 (25–35), 19 (18–20) apart, on 9th ventral annulus from rear; setae h1 8 (7–8), setae h2 82 (75–88). Female genital coverflap— 22 (18–25), 22 (19–25) wide, sculptured with basal 5 transverse lines basally and 12–14 longitudinal ridges apically, proximal setae on coxisternum ІІІ ( 3a ) 8 (6–9), 14 (13–16) apart. Male. Not seen. FIGURE 1. Hyborhinus linderae sp. nov. AD—anterior dorsal aspect of female; CGF — coxal-genital area of female; E — empodium; L — lateral view of female (Scale bar: AD — 30; CGF — 36; E — 13; L1, L — 50). Type data. Holotype , female, Tianmushan National Nature Reserve ( 30°22’N , 119°28’E ), Lin’an county, Zhejiang, China , 20-July-2007 , from Lindera obtusiloba Blume (Lauraceae) , collected by Guo-Quan Wang. Paratypes , 8 females , were mounted on 8 slides, with the same data as holotype . Relation to host. The mites are vagrants on the leaf undersurfaces, no visible damage seen. Etymology. The specific designation is derived from the generic name of the type host plant. Remarks. The species is close to Hyborhinus kallarensis Mohanasundaram, 1986 , but can be separated from the latter by the prodorsal shield with the median line present, coxisternal plates with lines and the female coverflap with basal transverse lines and apical longitudinal ridges. In H. kallarensis , the prodorsal shield without a median line, and the coxisternal plates and female coverflap are smooth ( Mohanasundaram 1986 ).
