Legs II 39 (38–39) long, femur 10 (9–10), basiventral femoral setae bv 15 (14–15); genu 5 (4–5) long, antaxial genual setae l’’ 10 (9–10) long; tibia 7 (7–8); tarsus 7 (6–7) long; tarsal empodium simple, 6­rayed, tarsal solenidion T tapered. Dorsal opisthosoma with 47 (44–48) annuli, smooth; ventral opisthosoma with 60 (56–60) microtuberculate annuli. Setae c2 43 (40–45) on ventral annulus 11 (10–11); setae d 50 (40–55) on ventral annulus 23 (21–24); setae e 29 (28–30) on ventral annulus 40 (39–41); setae f 35 (30–35) on 6th ventral annulus from rear. Setae h1 3 (3–4) long. Female genitalia 15 (14–15) long, 23 (21–24) wide, coverflap with 8 longitudinal ridges, setae 3a on coxisternum III 23 (20–25) long.

MALE: Unknown.

Material examined

Holotype, female, from Lonicera japonica Thunb. (Caprifoliaceae) , Guan’e Gou, Dangchang County, Gansu Province, China, 33°57’39”N, 104°19’45”E, 11 September 2005, collected by Z.­W. Song and X.­F. Xue. Paratypes, 5 females, with the same date as holotype.

Relation to host Mites are vagrant on the undersurface of leaves, causing no apparent damage.

Etymology

The specific designation japonicae is from the species name of the host plant, japonica .

Note

This species is similar to Phyllocoptes limsamus Boczek, 1996 , but can be differentiated by the tapered solenidion (knobbed in limsamus ), prodorsal shield with two submedian lines (four submedian lines in limsamus ), female genital coverflap with 8 longitudinal ridges (with 10 longitudinal ridges and obscure in limsamus ).
