Thorax. Black, covered with gray to brownish gray pruinosity; scutum with 4 black vittae, extending to scutoscutellar suture; only basal part of scutellum black, the rest orange; acr 0+1; dc 2+4; ial 0+2; pra long and strong, 1.2x as long as posterior notopleuron seta; notopleuron covered with small setulae; basisternum, anepimeron, meron bare; katepimeron with some setulae; anterior spiracle yellow, posterior spiracle brownish; katepisternal setae 1+2.

Wings. Light brownish, viens brown; basicosta yellow; subcostal sclerite brownish; costal spine short; radial node bare; distal part of R 4+5 and M straight; surrounding of dm-cu and r-m not clouded, dm-cu slightly curvate; calypter dark yellow; halter yellow.

Legs. Coxae, trochanter and tarsi black-brown, femora and tibiae entirely orange; fore tibia without median p; fore tarsus without sensory hairs; mid femur without distinct av row, with 2–4 pd on basal half, 1 pre-apical av, 3 pd; mid tibia with 2 p; only distal 1/3 of hind femur with 4–5 av, without pv; hind tibia with 1–2 av, 2 ad, 1 strong pd on distal 1/5, without apical pv; all pulvillus slightly longer than claws; all tarsi equal to their tibia in length.

Abdomen. Black, rotund, covered with dense gray pruinosity; each tergite with a median black vitta, posterolateral surface with large shifting patch; tergites 4 and 5 with rows of posterior marginal setae; sternite 1 with black setulae; sternite 5 lateral lobe subequal to basal lobe; cerci covered with dense setulae on distal 2/ 5 in posterior view; surstyli sickle-shaped in posterior view.

Female: Unknown.

Type material. Holotype, Ƌ, CHINA, Mt. Tianmu , 1500m, 119°26'E, 30°21'N, Zhejiang Province, 29.vi.2013, (Ping Wang) ( SYNU).

Paratypes, CHINA: 2 Ƌ, same data as holotype .

Remarks. This new species is similar to P. jinfengshanensis Feng & Ma, 2002 , but differs in the following features: pedicel red-brownish on distal part (in P. jinfengshanensis black), majority of arista hairs about 1.5x of postpedicel width (in P. jinfengshanensis 2.0x); hind femur with 4–5 av on distal 1/3, without pv (in P. jinfengshanensis with a row of av in full and pv on distal 1/3); abdomen rotund and middle part broad in dorsal view (in P. jinfengshanensis coniform); basal part of surstyli narrow, distal part of surstyli wide, surstyli sickle-shaped and bent as a right-angle at sub-basal (in P. jinfengshanensis slightly straight); cerci covered with dense setulae on distal 2/ 5 in posterior view (in P. jinfengshanensis cerci covered with sparse and short setulae on distal 2/ 5 in posterior view); surstyli sickle-shaped in posterior view (in P. jinfengshanensis slightly straight).

Etymology. The species name, in apposition, is based on the name of collector Ping Wang.

Geographic distribution. China: Zhejiang Province (Mt. Tianmu).
