Outer vertical seta longer than posterior vertical, about 2/3 of ocellar. Fronto-orbital with gray-white pruinosity. Distance between orbital setae longer than that between frontal setae. Parafacial with gray-white pruinosity, narrow, 1/4 of flagellum 1 width. Gena with gray-white pruinosity, about 1/12 of eye height. Occiput black in ground colour, with dense gray-white pruinosity. Apical margin of pedicel and basal half of flagellum 1 red-yellow, remaining brown. Flagellum 1 about 2.2 times as long as pedicel. Distance between end of antenna and epistoma about 1/2 of flagellum 1 length. Arista short ciliated in basal half, the longest hair about 2/3 of flagellum 1 width, bare in apical half. Palpi yellow, prementum black-brown.

Abdomen: Oval in dorsal view, longer than thorax, posterior margins of tergites and lateral lobes of sternite 5 yellow, remaining dark brown in ground colour, with gray-white pruinosity. Abdominal tergites with fainted brown median vittae; tergites 3–5 each with 1 pair of black brown rounded lateral spots, spot width about 1/2–3/4 of tergite length respectively. Tergite 5 with developed posterior marginal setae and discal setae, tergite 8 with 2 discal setae. End of surstyli and cerci cuspidal. Apicialula and dorsialulae of paraphallus slightly sclerotized, 1 pair of auricle-liked laterialulae. In profile, apical part of paraphallus with a small middle posterior window.
Female: Unknown.
Etymology: The specific name refers to male apical part of paraphallus with a small middle posterior window in profile (
