Leg I 36 (35-37), femur 10 (9-10), basiventral femoral setae (bv) 14 (13-15); genu 5 (4-5), antaxial genual setae (l') 22 (22-25); tibia 8 (8-9), paraxial tibial setae (l') 12 (10-12), located at 1/3 from dorsal base; tarsus 9 (8-9), setae ft' 19 (19-21), setae ft'' 22 (22-25), seta u' 10 (9-10); tarsal empodium (em) 8 (7-8), simple, 8-rayed, tarsal solenidion (ω) 10 (9-10), rod-like. Leg II 29 (28-30), femur 8 (8-9), basiventral femoral setae (bv) 16 (15-16); genu 4 (4-5), antaxial genual setae (l'') 8 (6-8); tibia 5 (5-6); tarsus 8 (7-8), setae ft' 9 (8-10), setae ft'' 23 (23-25), seta u' 9 (8-9); tarsal empodium (em) 8 (7-8), simple, 8-rayed, tarsal solenidion (ω) 10 (9-10), rod-like. Opisthosoma dorsally with a furrow in the middle; 35 (33-38) dorsal annuli, elliptical microtubercles on the rear margin; 74 (72-77) ventral annuli, microtubercles on the rear margin, circled on the anterior ventral annuli, and linear and spiny on the last posterior ventral annuli. Setae c2 28 (25-28) on ventral annulus 14 (12-14), 47 (45-48) apart; setae d 52 (48-52) on ventral annulus 28 (27-29), 35 (32-35) apart; setae e 33 (33-36) on ventral annulus 49 (47-51), 13 (12-14) apart; setae f 28 (26-29) on 6th ventral annulus from rear, 16 (16-17) apart.

MALE (n=2). Similar in shape and prodorsal shield arrangement to female, 155-169. Prodorsal shield 32-35, 28-31 wide; scapular setae sc 16-17, 21-23 apart. Opisthosoma dorsally with a furrow, 32-37 annuli, ventrally with 74-81 annuli, dorsal and ventral microtubercles are similar to females. Male genitalia 17- 18 wide, setae 3a 18- 20, 14-15 apart.

Type host plant.

Rosa beggeriana Schrenk ex Fisch. & C. A. Mey. ( Rosaceae ).

Relation to the host plant.

Vagrant on leaves; no apparent damage was observed.

Type locality.

Xinyuan county, Xinjiang Uygur Autonomous Region, China (43°36'29"N, 82°17'56"E), elevation 758 m; 29 July 2014, coll. Ji-Wei Li.

Type material.

Holotype: female (slide number SHZU Phyllocoptruta 1.1, marked Holotype). Paratypes: 16 females and 2 males mounted on 18 separate microscope slides.

Etymology.

The specific designation beggerianae comes from the epithet of the host plant, beggeriana.

Differential diagnosis.

This species is similar to Phyllocoptruta clematoclethra Xue, Song & Hong, 2010, from Clematoclethra sp. Maxim. ( Actinidiaceae ), but can be differentiated from the latter by admedian lines connected posteriorly (admedian lines separate in Phyllocoptruta clematoclethra ), scapular tubercles ahead of rear shield margin, scapular setae 16-18 (scapular tubercles on rear shield margin, scapular setae 3-4 in Phyllocoptruta clematoclethra ), female genital coverflap with 3 transverse basal lines (coverflap without transverse lines in Phyllocoptruta clematoclethra ) and 8-rayed empodium (5-rayed empodium in Phyllocoptruta clematoclethra ).
