Description (Male). Color
. Head dark brown; antenna, thorax, abdomen and hypopygium brown; palpus and legs yellowish-brown; wing fumose.
Head
(
Fig. 9
C, D). Eye bridge with 3 rows of facets. Prefrons with 22 setae. Clypeus with 1 seta. Palpus three-segmented, basal segment with 5–6 setae; 2nd segment with 11–15 setae; 3rd segment with 10–12 setae. Length/width of 4th flagellomere: 2.79–3.59.
Thorax
. Anterior pronotum with 6–12 setae, episternum 1 with 6–10 setae.

2.94–3.82 mm
, width/length: 0.32–0.37. c/w: 0.48–0.47. R1/R: 0.72–1.03. Y/X: 1.27–1.80. Y with 0–3 setae, stM with 1–5 setae, M and Cu with numerous setae.
Legs

Fig. 9
E). Length of spur/width of 1.59–2.03. Length of femur/ length of metatarsus: foreleg 0.81–0.87. Length of metatarsus/length of tibia: foreleg 0.75–0.77, hind leg 0.53– 0.61. Length of hind tibia/length of thorax 2.00–2.22. Fore tibia with 1 dorsal, 7–10 ventral, 3–11 prolateral and 4– 7 retrolateral spinose setae. Tarsal claws with large teeth.
Hypopygium
(
Fig. 9
A, B). Gonocoxite slightly longer than gonostylus. Ventral setosity of gonocoxite dense, 2–3 setae at the apicoventral corner greatly elongated, setosity sparse on intercoxal area of hypopygium. Gonostylus slender, with a sightly inflated apex, setosity dense at apex, with five apicomesial megasetae. Tegmen wider than long. Sternite 10 with 1–2 setae on each half. N = 6 for all measurements.

Remarks.
By the form of hypopygium, the new species is similar to
D. flavipes
(Meigen, 1804)
. But it differs in having the setosity sparser on the 4th flagellomere, y/x: 1.27–1.80 and a few setae on the intercoxal area on the hypopygium instead of an intercoxal lobe, while the setosity dense on the 4th flagellomere, y/x:> 2 and a small intercoxal lobe on the hypopygium in
D. flavipes
(Meigen, 1804)
.
Etymology.
This species is named after its
type
locality, Mt. Qingliangfeng at Zhejiang province,
China
.
