Type species: <i>Aleurodes spiniferus</i> Quaintance, 1903: 63–64, by original designation.</p><p><b>Diagnosis.</b> Pupal case usually dark brown or black in color, often surrounded by a short waxy fringe. Margin toothed, or serrated, not deflexed. Submarginal area not separated from dorsal disk. Submargin often with a row of small knobbed setae.

Longitudinal and transverse moulting sutures nearly reaching the margin. Cephalic, eighth abdominal and caudal setae present. First abdominal segment with a pair of glandular spines (usually treated as setae); in some species, this pair of spines with shrunk apices. Vasiform orifice often elevated, subcircular or subcordate; operculum similar in shape and almost filling the orifice, obscuring the lingula. Caudal ridges and furrow absent.</p><p>Remarks.
