Leg I 31 µm . Leg ІІ 29 (26–30), trochanter 2 (2), femur 12 (11–12), femoral setae ( bv ) 13 (13); genu 4 (3–4), genual setae ( l'' ) 10 (10–13); tibia 6 (5–6); tarsus 5 (5–6), inner fastigial tarsal setae ( ft' ) 20 (20), outer fastigial tarsal setae ( ft'' ) 7 (7), unguinal tarsal setae ( u' ) 5 (5); tarsal empodium entire, 7 (6–8), 6-rayed, tarsal solenidion 8 (8), unknobbed. Opisthosoma. Dorsum with 5 ridges, dorsal annuli 45 (45), smooth; ventral annuli 66 (66), with elongated microtubercles; setae c2 41 (35–45), on ventral annulus 10th; setae d 70 (70), 26 (25–28) apart, on ventral annulus 23th; setae e 22 (20–23), 10 (10) apart, on ventral annulus 44th; setae f 25 (25), 15 (15) apart, on 5th ventral annulus from rear; setae h1 absent, setae h2 60 (55–65). Female genitalia. Coverflap with and distal longitudinal ridges, 15 (15), 23 (23) wide, proximal setae on coxisternum ІІІ ( 3a ) 21 (18–25), 15 (15) apart. Male ( n = 1). Same as female, body fusiform, 138, 53 wide; prodorsal shield 45, 49 wide; male genital 19 wide, proximal setae on coxisternum ІІІ ( 3a ) 13, 13 apart. Type material. Holotype female, Huanglianshan National Nature Reserve ( 22°52′N , 102°17′E ), Lvchun County , Yunnan Province , China , 16 May 2009 , leg. Guo-Quan Wang , from Alnus nepalensis Don ( Betulaceae ) . Paratypes , 6 females and 1 male , same data as holotype . Relation to host. The mites are vagrants on the undersurfaces of the leaves, with no visible damage. Distribution. China ( Yunnan ). Etymology. The specific designation is derived from the generic name of the type host plant, gender masculine. Remarks. The new species is similar to P. yangensis Xue, Wang , Song & Hong, 2009, but can be distinguished from the latter by the smooth coxisternal plates and absent setae h1 . In P. yangensis , the coxisternal plates are sculptured with granules and setae h1 is present ( Xue et al. , 2009 ).
