MALE (n=5). Similar to the female, 190–200, 60–70 wide. Prodorsal shield 53–55, 60–70 wide; Scapular tubercles 17–18 apart, setae sc 4–5. Opisthosoma: 19–20 dorsal semiannuli, 69–73 ventral semiannuli.

Type material. Holotype: female (slide no. NJAUAcariEriYN61.1; marked Holotype), from Pinus tabuliformis Carr. (Pinaceae) , Erhai Park, Dali City, Yunnan Province, P.R. China, 25°41′47′′N, 100°08′28′′E, elevation 2142 m, 7 August 2009, coll. Xiao-Feng Xue. Paratypes: 8 females and 5 males on 13 microscope slides (slide no. NJAUAcariEriYN61.2–61.14), with same data as holotype.

Relation to host plant. Vagrant on terminal parts of pine needles. No damage to the host plant was observed.

Etymology. The specific designation granularpro is derived from the morphological details of the prodorsal shield. It is regarded as a noun phrase regardless of the gender and part of speech.

Differential diagnosis. This species is similar to P. taiwanensis Huang 2001 (we studied additional material of P. taiwanensis , including 5 females [slide no. NJAUAcariEriYN91.1–91.5], from P. tabuliformis, Kunming Botany Garden, Kunming City , Yunnan Province, P.R. China, 25°07′55′′N, 102°44′54′′E, elevation 1946 m, 9 August 2009, coll. Xiao-Feng Xue), but can be differentiated from the latter by having: a prodorsal shield design with two different kinds of granules (only some small granules seen dotting the shield in P. taiwanensis ); dorsal semiannuli with elliptical microtubercles (dorsal semiannuli with spiny microtubercles in P. taiwanensis ), prosternal apodeme present (absent in P. taiwanensis ).

Type material. Holotype female (slide no. NJAUAcariEriYN69.1, marked Holotype), from Juniperus chinensis Linn. (Cupressaceae) , Cangshan, Dali City, Yunnan Province, P.R. China, 25°41′47′′N, 100°08′28′′E, elevation 2142 m, 8 August 2009, coll. Xiao-Feng Xue. Paratypes: 14 females and 6 males on 20 microscope slides (slide no. NJAUAcariEriYN69.2–69.21), with same data as holotype.

Relation to host plant. Vagrant on terminal parts of needles. No damage was observed.

Etymology. The specific designation juniperiana is derived from the generic name of the host plant, Juniperus ; feminine in gender.

Differential diagnosis. This species is similar to Phyllocoptruta platycladusa Xue, Song, Amrine & Hong 2007 , but can be differentiated from the latter by: the absence of a median line and submedian lines on the prodorsal shield (a short median line and relatively long submedian lines are present in P. platycladusa ); having dorsal semiannuli with elliptical microtubercles on the wide, middorsal longitudinal furrow (dorsal semiannuli with microtubercles laterally in P. platycladusa ); coxal plates I with short lines, coxal plates II with granules (coxal plates I are smooth and coxal plates II have short lines in P. platycladusa ).
