4(3). Submarginal row of papillae present ( Figure 15 ), lingula visible and tri-lobed ............................. .......................................................................................................... Trialeurodes Cockerell

— Submarginal row of papillae absent, if present, does not occur in rows ..................................... 5

5(4). Cranial suture present; caudal and thoracic tracheal clefts and furrows present; vasiform orifice semi—hemispherical—shaped; lingula reduced or mostly obscured by operculum ................... ............................................................................................................ Dialeurodes Cockerell
