D e s c r i p t i o n: Body length 7.4 mm, wing length 5.7 mm.
H e a d: Eyes naked or with very few short white ciliae; frontal vitta black, sometimes red brown in lower part, 2.0 times as wide as fronto-orbital plate; frons 1.1–1.5 times as wide as anterior ocellus; without inter frontal setae; without orbital setae; frontal setae numerous, more than 10 pairs; fronto-orbital plate and parafacial with light gray tomentum, parafacial 1.1-1.5 times as wide as postpedicel; antenna black, postpedicel 1.3- 1.6 times as long as broad; arista short pubescent, the longest aristal hairs shorter than its basal diameter; lower facial margin not projecting, vibrissal angle and frontal angle in the same vertical plane in profile or vibrissal angle light behind frons; gena with light gray tomentum, genal height approx. 1/4 of eye height; anterior margin of gena with two rows of upcurved subvibrissal setulae; proboscis short, prementum with gray tomentum, palpus black, equal to the length of prementum.
T h o r a x: Ground color black with brown tomentum; scutum with three indistinct black vittae; with 1-2 pairs of long prst acr, almost as strong as prst dc; all acr long, one pair of post acr strong in front of scutellum, dc 2(3)+3, ial 0+2(3); with outer posthumeral seta; pra approx. 1.2 times as long as posterior notopleural seta; scutellum with brown tomentum like scutum, lower surface with pale hairs; notopleuron without hairs; katepisternal setae 1+2.
W i n g: Brown, base clear yellow; tegula black and basicosta brown; costa setulose only basally on ventral surface; without costal spine; radial node bare, calypters yellowish white with lustrous yellow margin; halters yellow.
L e g s: Entirely black; fore tibia with 2 pv, without ad; mid femur without distinct av, with 4–5 strong pv in basal half; mid tibia with 1 ad, 2 pd, 2 pv; mid tarsomere 1 without distinct setae; hind femur with almost complete row of strong av and pv; hind tibia with several ad, 3 strong pd, several av and pv; all tarsi longer than tibiae.
A b d o m e n: Black with brownish tormentum, black midline, black T-shaped on the first tergites; long, flat-shaped only the front segments; all tergites with long lateral and posterior marginal setae, tergite VI bare; sternite I with dense hairs, all sternites with dense and long setae; Sternite II-V and genitalia as illustrated in Figure 1.
Female: unknown.
This new species is similar to D. nasutula PANDELLE = D. aconiti RINGDAHL in HENNIG (1976) as it has very similar genitalia, but D. altophila has no interfrontal setae, brown tomentum, notopleura without hairs. Pra is longer than second npl.
