1. Postocular setae not arising in a single row, pair II slightly in front of pairs I & III, pair III arranged far behind I & II ( Fig. 5 ); ocellar setae pair III arising posterior to ocellar triangle; pronotum with transverse lines; male with one pair of thorn-like setae on tergite IX ( Fig. 49 )............................................ transeolinae [southern China and northern India ]

-. Postocular setae arising almost in a row; pair III missing ( Fig. 2 ); ocellar setae pair III arising within ocellar triangle, at least in front of posterior margin of hind ocelli; pronotum without obvious sculpture, sometimes with a few weak reticulations; male tergite IX with 2 pairs or no thorn-like setae................................................................ 2
