Legs. Entirely black, fore tibia with 1 median p and 2 p; mid femur without distinct av, with 3 pre-basal pd and 1–2 apical pd; mid tibia with 2–3 p and 1–2 pv; hind femur with a row of sparse av, slightly long on basal half, without pv; hind tibia with 3 av, 3 ad, 1 pre-apical pd, and 1 slightly short pd on basal part, without apical pv; all tarsi longer than tibia; fore claws and pulvillus longer than length of its tarsomere 5; mid claws and pulvillus equal to length of its tarsomere 5, hind claws and pulvillus shorter than length of its tarsomere 5.

Abdomen. Black and covered with dense grayish yellow pruinosity, suborbicular in dorsal view; syntergite 1+2 to tergite 5 each with black median vitta; tergites 1 to 5 without shifting patch; tergite 3 without median marginal seta; tergites 4 and 5 with complete row of marginal setae; sternite 1 bare; sternites 2 to 4 each with a pair of setae posteriorly; distal part of cerci without distinct inner protuberance in posterior view, basal part of cerci wide in posterior view; surstylus suborbicular.

Female. Unknown.

Type material. Holotype, ³, CHINA: Mt. Wuling, 2085 m, 117°91'E, 38°73'N, Chengde , Hebei Province, 17.vii.2016, (Qi Sun) ( SYNU).

Paratypes, CHINA: 4³, same data as holotype. ( Qi Sun ) ( SYNU) ; 84³, Liaoheyuan national Forest Park, 1630 m, 118°42’E, 41°31’N, Hebei Province, 15.vii.2016, ( Qi Sun ) ( SYNU) . 5³, Saihanba national Forest Park, 1516– 1656 m, 117°21’E, 42°41’N, Hebei Province, 10.vii.2016, ( Qi Sun ) ( SYNU) . 4³, Mt. Heilong, 1520 m, 116°12’E, 41°31’N, Hebei Province, 7.vii.2016, ( Qi Sun ) ( SYNU) .

Remarks. This species is similar to P. caesiipollinosa Xue, Rong & Du, 2014 , but differs in the following features: male with long plumose arista, the longest cilia about 1.4–1.5x of postpedicel in width (in P. caesiipollinosa 2.0x); abdomen covered with dense gray-yellow pruinosity, (in P. caesiipollinosa covered with sparse light gray pruinosity and slightly shinning), sternite 5 lateral lobe with one pair distinctly strong setae (in P. caesiipollinosa without strong setae), distal part of cerci without distinct inner protuberance in posterior view in male, basal part of cerci wide in posterior view (in P. caesiipollinosa distal part of cerci with distinct inner protuberance in posterior view, basal part of cerci narrow in posterior view), and surstylus suborbicular (in P. caesiipollinosa cylindrical).

Etymology. The species name, in apposition, is based on the name of collector Qi Sun.

Geographic distribution. China: Hebei Province (Liaoheyuan National Forest Park and Mt. Heilong).
