Gnathosoma 28 (27-30), projecting obliquely down, pedipalp coxal setae (ep) 3 (2-3), dorsal pedipalp genual setae (d) 9 (8-9), unbranched, cheliceral stylets 26 (25-27). Prodorsal shield 42 (40-43), 43 (41-44) wide, median line formed by lined short lines, admedian lines complete and connected posteriorly, submedian lines present at the posterior half, with several short lines and granules; frontal shield lobe rounded, broad-based, 5 (4-5). Scapular tubercles ahead of rear shield margin, 23 (22-25) apart, scapular setae (sc) 16 (16-18), projecting forward and convergent. Coxigenital region with 9 (7-9) microtuberculated semiannuli. Coxal plates with several short lines and granules, anterolateral setae on coxisternum I (1b) 11 (10-11), 12 (11-12) apart, proximal setae on coxisternum I (1a) 27 (26-31), 10 (9-10) apart, proximal setae on coxisternum II (2a) 46 (42-46), 25 (23-25) apart, tubercles 1b and 1a apart 7 (6-7), tubercles 1a and 2a 9 (8-9) apart. Internal coxisternal apodeme 3 (3-4). Legs with usual series of setae. 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. Setae h1 4 (3-4), h2 77 (75-83). Genital coverflap 13 (11-13), 19 (18-20) wide, coverflap with 3 transverse lines basally, 11 (11-13) longitudinal ridges distally, proximal setae on coxisternum III (3a) 43 (41-44), 15 (14-15) 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
).
