Halter short stemmed and brown. Leg pale yellow; apex of foretibia with dense group of setae (Fig. 3 F); claws untoothed.

However, the new species is easily distinguished by the medial inner side of gonostylus possessing distinctly separated lobes, with a pair of spines on each lobe (Fig. 3 B, 4). Etymology. - ensis (Latin) = a suffix denoting place, locality or country. This species is named after the locality where the species was first collected, Suwon-city.
