Previously known only from females taken in Japan, this species is here newly recorded from China and the male is described for the first time.

Male macroptera. Body smaller than female ( Figs 25–26 ); head and thorax brown ( Figs 26, 29 ); antennal segment VI much longer than that of female, about 1.4 times as long as combined length of segments I–V, with long setae and without microtrichia ( Figs 27–28 ); abdominal tergite VIII with complete posteromarginal comb; IX with one pair of CPS and SB1vestigial ( Fig. 30 ); abdominal sternites without discal setae; hypomere expanded at apex ( Fig. 30 ).

Measurements (male in microns). Body length 1481. Head, length 104; width across eyes 177. Ocellar setae III length 57. Pronotum, length 127; maximum width 175; posteroangular setae length, inner 60, outer 54. Metanotum median setae length 29. Fore wing length 860. Antennal segments I–VIII length 28, 40, 36, 35, 18, 197, 7, 8.
