Redescription.

Male: Head. Frons yellow, with large black triangle medially, without microtrichosity, evenly covered with short and thin black setulae. Ocellar triangle shining black. Lateral part of vertex entirely yellow without dark marks. Occiput yellow, medially black, slightly microtrichose close to eye margin, covered with short and thin black setulae. Gena yellow, 0.4 times as low as eye. Postgena yellow. Parafacialium yellow, 0.5 times as narrow as antennal grooves and as wide as flagellomere 1. Eye 1.3 times as high as wide. Lunula yellow. Face yellow, without narrow darkened band along the ventral edge. Clypeus pale yellow, darkened along ventral edge. Scape and pedicel light brown. Flagellomere 1 brown at base, almost black at apex, matted. Arista light brown. Antennal groove yellow, with thin silver-white microtrichosity. Proboscis brown. Palpus brown at base, black at apex.

Thorax. Yellow, with black pattern. Mesonotum with silver-white microtrichose medial stripe. Postpronotum with silver-white microtrichosity. Scutellum subshining yellow, faintly sculptured, with short black setulae over its ventral surface. Mediotergite yellow, with brown spot at the middle. Pleura yellow.

Setae. Four small orbital setae (dorsal orbital seta little longer than other ones), one divergent ocellar seta, one divergent postocellar seta, one long divergent lateral vertical seta, four divergent postocular setae, one short paravertical seta and one long convergent lateral vertical seta. Four genal setulae, eight postgenal setulae, one long genal seta. Two groups of supracervical setae over occipital foramen.

One postpronotal seta, two notopleural setae, one supra-alar seta, one prescutellar dorsocentral seta, one postalar seta, one intra-alar setae, two scutellar; anepimeral setae absent; one anepisternal, one katepisternal setae, also anepisternum and katepisternum covered with short black setulae.

Legs. Yellow. Tarsus, mid- and hindcoxae darkened to pale brown.

Wings. Hyaline, with yellowish apex. Cell r4+5 narrowly opened. Apices of veins R4+5 and M almost in contact. Posteroapical extension of cell bcu 0.3 times as short as the width of cell at its middle. Halter yellow.

Abdomen evenly short and thin, black, setulose. All tergites laterally yellow, brown at middle, syntergite 1+2 and tergite 3 completely brown. Sternites yellow.

Male genitalia. Surstylus with anteroventral lobe curved proximally at right angle, bears two spines at its medial margin; and with short posteromedial lobe covered with setulae on its ventral side. Cerci tapered at top, separated by narrow slit, covered with long setulae.

Body length, 4.7-5.5 mm. Wing length, 3.5-4.5 mm.
