Aleurocanthus Quaintance & Baker

Aleurocanthus Quaintance & Baker, 1914: 102 . Type species: Aleurodes spinifera Quaintance, 1903: 63 –64, by original description.

Diagnosis. Puparia mostly in groups, male puparia usually much smaller than female, exuviae of earlier instars habitually remain on the dorsum of puparia, cuticle usually black, sometimes pale brown, often with fringe of marginal wax secretion; margin lobulate, serrate or toothed, wax secreting glands often present at base of marginal “teeth” in the form of transparent area. Tracheal pore areas not indicated except A. hirsutus (Maskell) . Dorsum with stout glandular spines on submargin and subdorsum, spines apically pointed or fimbriate; sometimes with drops of gelatinous yellow wax at apices. Longitudinal and transverse moulting sutures reach the margin. Submargin usually with minute setae. Cephalic, eighth abdominal and caudal setae present. First abdominal segment with a pair of glandular spines often referred to as setae. Vasiform orifice posteriorly elevated, subcircular to subcordate or rectangular, floor usually weakly ridged, almost occupied by operculum, lingula obscured. Caudal ridges and furrows absent. Ventrally, submargin sometimes with one or more rows of wax plates; length of antennae varies between male and female puparia, leg pads and spiracles well developed. Martin (1999) stated that puparia of some species have glandular spines reduced and located on tubercles; these species were included in Aleurocanthus based on the presence of spines in third instar larvae.
