Lower interfrontal setae shorter than upper interfrontal setae and the distance between each other equaled to that between upper interfrontal setae. Lower fronto-orbital setae present, which shorter than supra-antennal setae and closed to upper fronto-orbital setae. First flagellomere brown, 0.165 mm long, with an aspect ratio of 1.58:1; arista 0.40 mm long, 2.40 times as long as that of first flagellomere. Palpus yellowish brown, with 5 short setae apically.
