Prodorsal shield 60 (59–61) long, 77 (75–80) wide; prodorsal shield with broad, round frontal lobe, the median line nearly complete, admedian lines concave at anterior 1/3 and 2/3, median and admedian lines connected by transverse lines at posterior 2/3, 3 pair of submedian lines incomplete and connected by transverse lines. Scapular tubercles ahead of rear margin, 24 (23–25) apart, scapular setae sc 8 (6–9) projecting mediad. Prosternal apodeme present. Coxal area with short lines; setae 1b on coxisternum I 6 (5–6), setae 1a on basal coxisternum I 15 (11–20), setae 2a on coxisternum II 53 (50–53). Legs I 39 (36–40) long, femur 12 (12–13), basiventral femoral setae bv 12 (12–13); genu 6 (5–6) long, antaxial genual setae l’’ 37 (35–40) long; tibia 9 (8–9), paraxial tibial setae l’ 10 (9–10), setae located 2/3 from dorsal base; tarsus 7 (6–7) long; tarsal empodium simple, 5–rayed, tarsal solenidion T knobbed. Legs II 33 (34–36) long, femur 11 (11–12), basiventral femoral setae bv 10 (10–11); genu 5 (5–6) long, antaxial genual setae l’’ 11 (10–12) long; tibia 7 (6–7); tarsus 6 (6–7) long; tarsal empodium simple, 5­rayed, tarsal solenidion T knobbed. Dorsal opisthosoma with 57 (55–58) annuli, smooth, ventrally with 90 (86–92) microtuberculate annuli. Setae c2 30 (29–32) on ventral annulus 13 (11–13); setae d 60 (55–60) on ventral annulus 34 (30–35); setae e 40 (39–42) on ventral annulus 58 (57–60); setae f 27 (25–30) on 6th ventral annulus from rear. Setae h1 4 (3–4) long. Female genitalia 22 (20–24) long, 36 (35–37) wide, coverflap with 18 longitudinal ridges at base, setae 3a on coxisternum III 9 (8–10) long.

MALE: Unknown.

Material examined

Holotype, female, from Picea asperata Mast. (Pinaceae) , 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, 4 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 dangchangi is from the county where the host plant and the mite were found, Dangchang County.

Note

This species is similar to Phyllocoptes quzhounensis Kuang & Gong, 1998 , but can be differentiated by prodorsal shield with median, admedian and submedian lines (smooth in quzhounensis ), empodium 5­rayed (empodium 4­rayed in quzhounensis ), paraxial tibial setae l’ located 2/3 from dorsal base (paraxial tibial setae l’ located 1/3 from dorsal base in quzhounensis ), and basal coverflap with 18 short longitudinal ridges ( quzhounensis with 14 normal longitudinal ridges on the coverflap).
