Legs II 27 (25–28) long, femur 7 (7–8), basiventral femoral setae bv 11 (10–11); genu 4 (4–5) long, antaxial genual setae l’’ 11 (11–12) long; tibia 6 (6–7); tarsus 6 (5–6) long; tarsal empodium simple, 6­rayed, tarsal solenidion T tapered. Dorsal opisthosoma with 51 (50–52) annuli, with round microtubercles on rear annular margins, ventrally with 73 (70–75) microtuberculate annuli. Setae c2 48 (45–53) on ventral annulus 12 (11–12); setae d 52 (47–55) on ventral annulus 30 (27–32); setae e 38 (35–41) on ventral annulus 52 (50–52); setae f 25 (23–27) on 6th ventral annulus from rear. Setae h1 6 (5–6) long. Female genitalia 18 (17–18) long, 25 (25–26) wide, coverflap with 2 diagonal ridges and basal granules, setae 3a on coxisternum III 30 (28–31) long.

Material examined

Holotype, female, from Picea asperata Mast. (Pinaceae) , Huayang Town, Yang County, Shaanxi Province, China, 33°35’23”N, 107°32’26”E, 16 August 2005, collected by Z.­W. Song and X.­F. Xue. Paratypes, 6 females and 2 males, 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 asperatae is from the species name of the host plant, asperata .

Note

This species is similar to Phyllocoptes multilinea Huang, 2001 , but can be differentiated by dorsal opisthosoma annuli with round microtubercles on rear annular margins (dorsal opisthosoma annuli with spine microtubercles in multilinea ), coxal area with short lines (with granules in multilinea ), 9 coxigenital annuli (2–3 in multilinea ) female genitalia coverflap with 2 diagonal ridges (with 8 longitudinal ridges in multilinea ).
