A rather small species; abdomen long ovate; 2 katepisternal setae; 4 postsutural dorsocentral setae; 2–3 presutural acrostichal setae; apical scutellar setae absent; wing hyaline, without tinge along r-m crossvein; male cerci narrow and curved dorsally. Description. Body length: 6.3–8.7 mm . Male . Head black in ground color, reddish brown on narrow triangular portion below eye and pale yellowish brown on lower portion of face; parafrontal, parafacial, gena and occiput with dense grayish-white pruinosity, somewhat silvery and more whitish on parafacial; face with whitish pruinosity; frontal vitta velvety dark brown; antenna dark brown, apical portion of pedicel reddish brown; palpus reddish yellow, narrowly darkened on basal portion. Frons at narrowest point about 0.22 of head width; frontal vitta weakly widened anteriorly, nearly as wide as parafrontal at middle; frons in lateral view about 1.3 times as long as face; parafacial 0.8–0.9 times as wide as postpedicel at mid height in horizontal position; gena about 1/2 of eye height in horizontal position (3/ 8 in profile); face weakly concave, lower margin warped forward, slightly expanded beyond base of vibrissa. Inner vertical seta rather fine, 1/2–5/8 as long as eye height; 9–11 frontal setae, lowest seta nearly level with apex of pedicel; ocellar setae about 3/4 as long as inner vertical seta; parafrontal with 2–3 rows of fine short black hairs, only 1–2 descending just below lowest frontal seta; parafacial bare; occiput bulged, with 2–3 rows of black hairs behind postocular setae. Antenna falling short of lower margin of face by about 1/4 length of pedicel; postpedicel about 2 times as long as wide, about 2 times as long as pedicel; arista with 2nd aristomere about 2 times as long as wide, 3rd aristomere thickened on its basal 2/5. Prementum short, about as long as postpedicel; palpus nearly cylindrical, only slightly widened near apex, about 4/5 as long as pedicel and postpedicel combined. Thorax black in ground color, apex of scutellum sometimes narrowly reddish brown; scutum with rather thin grayish pruinosity, somewhat brownish near median portion; pleura with thin grayish pruinosity; scutum with 5 broad longitudinal vittae, median vitta sometimes indistinct on presutural area, outer vitta distinctly wider than pruinose portion between inner and outer vittae on postsutural scutum. Two posthumeral setae; 2 or 3 presutural and 3 postsutural acrostichal setae; 4 postsutural dorsocentral setae; scutellum with a pair of discal and 3 or 4 pairs of marginal setae, lateral scutellar seta sometimes single, apical setae absent; all marginal scutellar setae very long, about 2 times as long and scutellum, if 2 lateral setae present, then anterior one fine; subapical scutellar setae close at bases and parallel to each other, distance between their bases about 1/2 that between basal and subapical setae; 2 katepisternal setae; anepimeral seta extending at most to posterior margin of upper calypter; anatergite with several fine short hairs. Wing hyaline, weakly tinged with pale brown throughout, without dark tinge on r-m crossvein; calypter whitish; second costal sector about 2/5 length of 3rd and 3rd sector subequal in length to 4th; vein M nearly rightangled at bend, sometimes with a very short appendage, length of M from dm-cu crossvein to bend about 1.5 times distance between bend and wing margin, and about 3/4 as long as dm-cu crossvein. Legs black, hind tibia sometimes dark reddish brown ventrally; fore tibia with 4–5 anterodorsal, 1–2 posterodorsal and 2–3 posterior setae; mid tibia with 3 anterodorsal, 2–3 posterodorsal and 1 ventral setae; hind tibia with a row anterodorsal setae of irregular length, 3–5 posterodorsal and 2 ventral setae; claws and pulvilli long, subequal in length to 5th tarsomere. Abdomen black in ground color; dorsum with whitish pruinosity on anterior 1/2–1/4 of 3rd tergite and anterior 1/2–2/3 of 4th and 5th tergites, pruinosity thinner medially and faded posteriorly on each tergite, a broad mid-dorsal longitudinal vitta distinct on 3rd to 5th tergites; venter with thin grayish-white pruinosity throughout. Hairs on dorsum suberect, dense and rather long, becoming sparser posteriorly, on venter fine, short and dense; syntergite 1+2 without median marginal setae and with 2 lateral marginal setae; 3rd tergite with a pair of strong median discal and median marginal setae and 2 lateral marginal setae; 4th tergite with a pair of strong median discal and a row of marginal setae; 5th tergite with regular rows of strong discal and marginal setae; 5th sternite with posterior lobe occupying about posterior 1/3 of its length, inner posterior corner of posterior lobe roundly produced, with dense long hairs; median membranous portion rather narrow, T-shaped. Terminalia: 6th tergite to epandrium with very thin grayish pruinosity; 6th tergite rather long, fused with syntergosternite 7+8 medially, about 1/2 as long as syntergosternite 7+8, with a row of rather strong marginal setae and 1–2 rows of fine hairs; epandrium large, with a short posterior invagination; cerci in dorsal view strongly narrowed from base to basal 2/5, then almost parallel-sided to apex, in lateral view well curved medially, apex narrowly truncated; surstylus narrow, nearly straight in lateral view, with 2 short and strong spines at apex; hypandrial arms broad; pregonite wide, posterior margin curved outwardly with several long and short hairs; postgonite narrow, weakly widened posteriorly; epiphallus absent; basiphallus rather long; distiphallus broad rectangular in lateral view. Female . Differs from male as follows: antenna with scape and pedicel more reddish, especially on bases and apices; frons at narrowest point about 0.31 of head width; frons in profile about 1/2 times as long as face; parafacial width about 0.83 of postpedicel ( 0.67 in profile); head setae stronger, inner vertical seta more than 3/4 length of eye height; outer vertical seta developed, about 2/3 as long as inner vertical seta; 1 outwardly directed prevertical seta, about 4/5 as long as outer vertical seta; ocellar setae nearly as long as outer vertical seta; 2 subequally long proclinate orbital setae, subequal in length to outer vertical seta; 6–8 frontal setae; antennal pedicel with a long seta which is shorter than pedicel; postpedicel 1.6–1.8 time as long as wide and 1.6–1.8 times as long as pedicel; palpus clavate, slightly longer than postpedicel; legs with claws and pulvilli shorter than 5th tarsomere; abdominal hairs shorter and appressed on 3rd and 4th tergites. Terminalia: 6th tergite broadly divided into short and high hemitergites, with a row of strong setae marginally; 7th hemitergite subequal in length to 6th hemitergite, lower than the latter, with a row of rather sparse strong setae medially; 7th sternite weakly constricted posteromedially, ventromedian portion weakly membranous; 8th tergite absent; epiproct divided medially into 2 small sclerites, each with a strong seta.
