( Figure 1 View Figure 1 )
Type material
Holotype: male, China: Jilin Prov.: South slope of Changbaishan Mt. , 1720 m, 11 August 2004, coll. Liu Xingyue (CAU) ; Paratype: male, China: Jilin Prov.: Baihe, Changbaishan Mt. , 740 m, 6 August, 1986, coll. Bu Wenjun (NKU) .
Diagnosis
Middle and lower postocular bristles pale. Antenna yellow except apex of first flagellomere black; first flagellomere 1.55 times longer than wide. Fore coxa yellow, mid and hind coxae black. Mid tarsus with apex of tarsomere 3 and tarsomeres 4–5 flattened. Hind femur with 2–3 preapical bristles and one row of 10–12 pale ventral hairs on apical half (shorter than thickness of femur).
Description
Male. Head metallic green with pale gray pollen. Face with pale brown pollen, nearly as wide as first flagellomere. Hairs and bristles black, middle and lower postocular bristles (including postero-ventral hairs) pale. Antenna ( Figure 1A View Figure 1 ) yellow except apex of first flagellomere black; first flagellomere 1.55 times longer than wide; arista black, with basal segment 0.4 times as long as apical segment. Proboscis brown with black hairs; palpus yellow with black hairs and one black apical bristle.
Thorax dark metallic green with pale gray pollen. Hairs and bristles on thorax black. Six strong dc, nine paired acr short and hair-like; scutellum with one pair of strong bristles and several pale short marginal hairs. Propleuron pale and black haired, with one black bristle at lower part. Legs [hind tarsomere 5 broken off] yellow, fore coxa yellow, mid and hind coxae black with yellow apex. Fore and mid tarsi from tarsomere 2 onward brownish to brown, mid tarsus ( Figure 1C View Figure 1 ) with apex of tarsomere 3 and tarsomeres 4–5 flattened and black; apex of hind tibia and hind tarsus black. Hairs and bristles black; mid and hind coxae each with one outer bristle; mid femur with one preapical bristle, hind femur with two preapical bristles and one row of 10–12 pale ventral hairs on apical half (shorter than thickness of femur). Fore tibia with two to three ad, two pd and one to two pv, apically with two bristles; mid tibia with four to five ad, two pd and one av, apically with four bristles; hind tibia with four ad, five pd, one apical d, one av and four v, apically with three bristles. Hind tarsomere 1 with two d, one l and four v. Relative lengths of tibia and five tarsomeres LI 1.9: 1.0: 0.5: 0.45: 0.3: 0.25; LII 2.7: 1.5: 0.75: 0.55: 0.4: 0.2; LIII 2.8: 1.35: 1.25: 0.7: 0.5:?. Wing ( Figure 1B View Figure 1 ) hyaline, anterior area above M distinctly tinged with grayish. M without rudimentary M 2. CuAx ratio 0.6. Squama yellow with black hairs; halter pale yellow.
Abdomen metallic green. Hairs and bristles on abdomen black. Male genitalia ( Figures 1D–F View Figure 1 ): Epandrium longer than wide, inner epandrial lobe short, outer
epandrial lobe wide and short with two pale apical bristles; cercus with marginal processes and bristles; hypandrium narrow apically, aedeagus slender.
Measurements of male (mm). Body length 4.5–4.9 mm, wing length 4.3–4.5 mm.
Female. Unknown.
Etymology
The new species is named after its type locality, Jilin .
Remarks
The new species is very close to D. amurensis Stackelberg except the mid femur with one preapical bristle and the hind femur with one row of 10–12 pale ventral hairs on apical half. In D. amurensis Stackelberg , the mid femur has two preapical bristles and the hind femur has no ventral hairs ( Stackelberg 1930).
Distribution
China (Jilin).
