Prodorsal shield 46 (43–48) long, 56 (53–57) wide; prodorsal shield with frontal lobe, the median line absent, the admedian lines subparallel, submedian lines from apical third to rear. Scapular tubercles ahead of rear margin, 19 (18–20) apart, scapular setae sc 8 (8–9) projecting mediad. Prosternal apodeme present. Coxal area I with short lines, coxal area II smooth; setae 1b on coxisternum I 8 (7–9), setae 1a on basal coxisternum I 18 (15–20), setae 2a on coxisternum II 43 (43–45). Legs I 40 (38–41) long, femur 10 (10–11), basiventral femoral setae bv 12 (11–12); genu 5 (4–5) long, antaxial genual setae l’’ 25 (23–27) long; tibia 8 (7–8), paraxial tibial setae l’ 6 (5–7), setae located at center of the tibia; tarsus 7 (6–7) long; tarsal empodium simple, 6­rayed, tarsal solenidion T tapered. Legs II 39 (36–39) long, femur 10 (9–10), basiventral femoral setae bv 12 (12–13); genu 5 (4–5) long, antaxial genual setae l’’ 11 (9–12) long; tibia 6 (6–7); tarsus 7 (5–7) long; tarsal empodium simple, 6­rayed, tarsal solenidion T tapered. Dorsal opisthosoma with 40 (38–41) annuli, smooth; ventral opisthosoma with 51 (50–52) smooth annuli. Setae c2 30 (30–31) on ventral annulus 7 (6–7); setae d 30 (29–30) on ventral annulus 16 (16–17); setae e 33 (30–35) on ventral annulus 33 (32–35); setae f 30 (30–31) on 6th ventral annulus from rear. Setae h1 5 (5–6) long. Female genitalia 12 (11–13) long, 20 (19–20) wide, coverflap with 8 longitudinal ridges, setae 3a on coxisternum III 22 (20–25) long.

MALE: (n = 7) 150–160 long, 50–54 wide; genitalia 3–4 long, 18–19 wide, setae 3a on coxisternum III 12–15 long.

Material examined

Holotype, female, from Lycium chinense Mill. (Solanaceae) , Guan’e Gou, Dangchang County, Gansu Province, China, 33°57’39”N, 104°19’45”E, 12 September 2005, collected by X.­F. Xue and Z.­W. Song. Paratypes, 12 females and 7 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 lyciumi is from the generic name of the host plant, Lycium .

Note

This species is similar to Phyllocoptes fabris Xue & Hong, 2005 , but can be differentiated by prosternal apodeme on coxal area present (absent in fabris ), ventral annuli smooth (ventral annuli with microtubercles in fabris ), female genital coverflap with 8 longitudinal ridges (with 6 diagonal ridges in fabris ).
