Anthocoptes lindleyanius sp. nov. ( Figs 14–19 )

Diagnosis. Body fusiform, light yellowish in color. Gnathosoma projecting obliquely downward. Prodorsal shield frontal lobe present, median line absent, admedian and submedian lines completed. Scapular tubercles nearby rear shield margin, scapular setae (sc) directing to rear. Coxisternal plates smooth, prosternal apodeme present. Legs with tarsal empodium simple, 4-rayed, tarsal solenidion unknobbed. Opisthosoma with 16 –18 dorsal annuli and 57–63 ventral annuli, dorsal annuli sculptured with lines. Female genitalia coverflap smooth.

Leg II 27 (26–28), trochanter 2 (2), femur 9 (9–10), basiventral femoral setae (bv) 8 (8– 10); genu 4 (4), antaxial genual setae (l'') 10 (8–10); tibia 5 (5); tarsus 7 (6–7), setae ft' 7 (4–7), setae ft'' 15 (15–17); tarsal empodium (em) 6 (5–6), entire, 4-rayed; tarsal solenidion (ω) 7 (6–7), unknobbed. Opisthosoma with 17 (16–18) dorsal annuli, anterior 13–14 broad dorsal annuli following with posterior 3–4 narrow and thin annuli; ventrally with 63 (57–63) semiannuli, with round microtubercles on rear annular margins except caudal 5–6 ventral annuli with elongated microtubercles. Setae c2 20 (15–20) on ventral annulus 10–11, 49 (34–49) apart; setae d 40 (30–40) on ventral annulus 23– 24, 34 (27–34) apart; setae e 13 (12–13) on ventral annulus 39–40, 18 (15–18) apart; setae f 20 (15–20) on 5th ventral annulus from rear, 17 (11–17) apart. Setae h1 2 (2–3), 6 (5–6) apart; setae h2 60 (50–60), 10 (9–10) apart. Female genitalia 12 (10–12), 20 (20–22) wide, coverflap smooth, setae 3a 10 (10–11), 15 (12–15) apart.

Male. Unknown.

Material examined. Holotype, female, from Buddleja lindleyana Fortune (Scrophulariaceae) , Wanglang Nature Reserve (33º54′41′′N, 104º09′18′′E; elev. 2440 m), Pingwu County, Sichuan, China, 15 August 2016, coll. Manchao Xie. Paratypes. 10 females, the same data as holotype; 20 females, from Buddleja davidii Franch. (Scrophulariaceae) , Wanglang Nature Reserve (32º57′21′′N, 104º07′20′′E; elev. 2513 m), 17 August 2016, coll. Manchao Xie.

Relation to host. The mites are vagrants on the undersurfaces of the leaves, no obvious damage seen.

Etymology. The specific name is from the Latin lindleyani and us, lindleyani is derived from the host plant, and us is for masculine gender end.

Remarks. This new species is the second eriophyid mites reported from Buddleja lindleyana besides Aculops buddlejaes Xue, Song & Hong, 2010 in Shaanxi.

This species is similar to A. loricatus ( Nalepa,1889) by the shield design with median line absent, the coxal plates smooth and the coverfalp smooth. The new species can be differentiated from the latter by the scapular tubercles nearby rear shield margin, the shield design with admedian and the submedian lines completed, while A. loricatus has the scapular tubercles set on rear shield margin, the shield design with admedian lines absent and the submedian lines uncompleted.
