The Drapetini currently includes 18 genera, of which 9 genera ( Chersodromia Walker , Crossopalpus Bigot , Drapetis Meigen , Elaphropeza Macquart , Megagrapha Melander , Nanodromia Grootaert , Pontodromia Grootaert , Sinodrapetis Yang, Gaimari & Grootaert , and Stilpon Loew ) have been recorded from the Oriental Region, but only seven genera of Drapetini are currently known from Singapore . Megagrapha and Sinodrapetis are lacking. Almost all these groups are worldwide in distribution but Nanodromia and Pontodromia are found in the Oriental and Australasian regions only.
