Redescription based on the specimens collected in Beijing, China. MALE. Body length about 5.00 mm. Eye with long and dense brownish hairs; facets slightly enlarged on anterior margin in upper part; fronto-orbital plate and parafacial with dense grayish-silvery pollinosity; frons about as wide as the distance between two posterior ocelli at narrowest point; frontal vitta black, with grayish-white pollinosity, linear at narrowest point; frontal setae six to eight, stout, situated on the lower 3/4 of frons, orbital setae absent; postocular setae short, in one row, with some occipital setae behind the postocular setae on vertex; parafacial bare, at middle about 0.75x to 1.00x as wide as the width of postpedicel; antenna black, postpedicel about 2.00x longer than wide, arista black, bare or short plumose, slightly swollen in basal part; epistoma about at the same level of vibrissal angle, vibrissal angle behind frontal angle in profile; subvibrissal setae in one row, lateral with one or two rows of short setae; gena and genal dilation with fine black setae, upper margin of gena without upcurved seta; prementum with thin grayish-yellow pollinosity, its length about 2.00x as long as its width; palpus black, claviform, as long as the length of prementum. Thorax ground-color black, notum with dense grayish-yellow pollinosity, without distinct vitta; presutural acr biserial, hair-like, only prescutellar pairs long, dc 2+3, ia 0+2, pra 1, stout, about 2/3 as long as the length of posterior notopleural seta; notopleuron without seta; basisternum, proepisternum, anepimeron, meron and katepimeron bare; katepisternal setae 1+1, katepisternum with some setae and without ventral spine; anterior spiracle yellowish, posterior one brown; calypters yellowish, the lower one equal in size to the upper one. Wing brown; veins dark brown; tegula black; basicosta yellowish-brown; costal spine inconspicuous; node of Rs bare on ventral and dorsal surfaces; vein M straight, slightly close to vein R4+5 distally; crossveins without cloud; haltere brownish-yellow and dark drown at basal part. Legs black; fore coxa without anterior spine on ventral surface, fore femur with complete pv row, fore tibia with one apical d, each segment of fore tarsi with one pair of slender sensory setae; mid coxa without any hook-like spine or spine-like seta, mid femur with stout and sparse av row in basal part, becoming shorter and denser towards apex, with a gap in subapical part, with three or four comb-like setae in distal part, with stout pv row, slightly biserial in median part, p row long and sparse, mid tibia slightly swollen in distal 2/3, with two or three ad and two pd, and with numerous slender setae on ventral surface, the longest one slightly shorter than mid tibial width in distal part, mid first tarsomere with a basal tooth-like spine on ventral surface, the length of the spine about 1.50x to 2.00x as long as tibial width in basal part; hind coxa bare on posterior surface, hind femur slightly curved, with a complete av row, becoming stout and slightly upcurved in distal 3/4, the length of the longest av more than 2.00x of femur width in distal half, with one row of slender setae in posterior surface in basal part, becoming to posterodorsal surface in median part, and to posteroventral surface in distal part, several setae with tip curved in distal part, hind tibia with one stout median av, one ad, and one median a. Abdomen long and flattened, ground-color black, with dense greenish-gray pollinosity; syntergite 1+2 to tergite 4 each with one dark broad median triangular vitta, tergite 5 with one dark median vitta in basal part, each tergite with long lateral marginal setae; sternite 1 with four to six long setae on each side; terminalia see Chillcott (1961: 30, 34, 172).
