Diagnosis. Without ors; basisternum bare; katepimeron and notopleuron setulose; posterior dc 4; mid tibia with 2–3 p, 1–2 pv; abdomen without yellow parts and not hyaline; sternite 5 processes with one pair of distinctly strong setae; basal part of cerci wide in posterior view, distal part without distinct inner protuberance.
Description. Male. Body length 6.0– 7.5 mm. Head. Eye covered with moderate long brown cilia; frons narrow, about equal to or narrower than the width of anterior ocellus; fronto-orbital plate contiguous in the middle, frontal vitta black; 11–13 fr, extending to anterior ocellus, 6 fr on lower 2/5 long and strong, the rest of fr distinctly short and slightly longer than eye cilia; ors absent; ocellar seta long and strong, subequal to lower fr in length; margin of fronto-orbital plate and parafacial covered with silvery white pruinosity, parafacial width about 1.1–1.2x of postpedicel in width; antenna black, postpedicel about 2.8–3.0x as long as wide; arista long plumose, the longest cilia about 1.4–1.5x of postpedicel in width; lunule dark brown; epistoma not projecting, vibrissal angle situated behind frontal angle; gena entirely black, anterior margin of gena with 2 rows upcurved setulae, gena about 1/4 of eye in height,; palpus black, about 1.2x of prementum in length; prementum covered with gray pruinosity and 2.5x as long as high.
Thorax. Black, covered with sparse gray pruinosity; scutum with 4 black vittae, extending to 2/3 of scutellum; acr 0+1; dc 2+4; ial 0+2; pra long and strong, about 2.0–2.5x as long as posterior notopleural seta; notopleuron covered with small setulae; basisternum and meron bare; katepimeron setulose; katepisternal setae 1+2; posterior and anterior spiracles brown; scutellum entirely black, lateral margin and ventral margin of scutellum bare.
Wings. Semihyaline and brownish; tegula black; basicosta dark-brown; costal spine short; lower surface of C with hairs, Sc bent as a bow; radial node bare; surrounding of r-m and dm-cu not clouded; dm-cu bent slightly; R 4+5 and M straight, parallel on distal part, the former slightly upward bent in apical part; calypter brown-yellow, halter yellow.
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).
