Description. Male. Body length 9.1–9.3 mm, wing length 8.4–8.6 mm. Body (Fig. 1A) yellow.  
Head (Figs 1B–D). Frons hairy on anterior half, wider than long, with a pair of pale brown stripes extending to two sides of ocellar triangle; anterior frontal margin extending over the lunule and antennal bases; two upper fronto-orbital setae retroverted, anterior fronto-orbital seta slightly shorter than posterior fronto-orbital seta. Ocellar triangle shining, ocellar setae developed, extending forward and close to frontal margin, divergent apically; postocellar setae parallel; rows of setulae scattering between anterior ocellar and postocellar setae. Face concaved medially, with ventral margin light brown. Gena two-thirds height of eye, with several long setulae and 2 strong genal setae. Antenna with very short scape and pedicel, and first flagellomere elongated oval; arista black and mostly bare, except for basal one-fifth pale yellow with sparse rays, which short than basal width of arista. Clypeus, palpus and proboscis pale yellow to yellow.  
 Thorax (Figs 1E–F). Mesonotum with a pair of brown slender medial stripes, two pairs of brown thin stripes before or beyond transverse suture, and 0+2–3 dorsocentral setae, 1 postsutural intra-alar seta, 2 setae before supra-alar seta, 1 proepisternal seta, a row of 6 katepisternal setae along upper margin of katepisternum. Scutellar suture black in the middle. Legs with all apex of femora and apical one-fourth of tibiae brown; apex of tarsomeres 1–2 and apical half of tarsomere 3 pale brown, and tarsomeres 4–5 dark brown. Fore tibia with 1 preapical dorsal seta and 1 apicoventral seta. Mid tibia with a vertical row of posterior dorsal setae in male, 1 preapical dorsal seta and a horizontal row of strong apicoventral setae. Hind tibia with a thin and long preapical dorsal seta, 1 apicoventral seta. Wing (Fig. 1I) pale yellow hyaline, with small brown spots on apex of Sc, R 2+3, R 4+5 and M 1+2, and brown clouds on r-m and dm-cu, and R 1 with dorsal setulae along entire length, vein M 1+2 curved forward in ultimate section and converged toward R 4+5.   
Abdominal tergites (Figs 1G–H) 2–4 with thin brown posterior margin. Male genitalia (Figs 2A–C) with epandrium narrow dorsally and widen ventrally with many setae, which equal to or shorter than those on syntergosternite, anterior epandrial process longer than surstylus and broadly rounded at apex, surstylus rod-shape with 2–3 basal setae; hypandrium Y-shaped, hypandrial apodeme short; pregonite slender with 1 seta, postgonite broaden basally; phallus long with a pair of sharp lateral processes in the middle, distal half densely hairy, and slightly twisted at apex.  
Material examined. China, Inner Mongolia, Hulunbeir, Jinhe, Hanma National Nature Reserve, 200 m stream plank road, 2♂, Malaise-trapping, 835 m, 12 August 2016, Shen, R. R. leg.; China, Inner Mongolia, Hulunbeir, Jinhe, Hanma National Nature Reserve, Bono River, Suspension bridge, 1♂, Malaise-trapping, 854 m, 3 May 2016, Shen, R. R. leg.

 Remarks. The species is reported in China for the first time. It is similar to D. puellaris Steyskal, 1957 from China (Sichuan), but be distinguished from the latter by the above key. The sequence of the cytochrome oxidase I (COI) of this species was uploaded to NCBI and deposited in GenBank under accessions OL851802 (Dryomyza anilis).
