Aleuroparadoxus Quaintance and Baker, 1914

Aleuroparadoxus Quaintance and Baker 1914: 104 . Type species: Aleyrodes iridescens Bemis 1904: 487–489 , by monotypy.

Distribution. New World. Nearctic (4 species); Neotropical (14 species) (see Table 1 ).

Hosts. Various trees and shrubs ( Table 1 ).

Diagnosis. Aleuroparadoxus comprises species with the following combination of characters: puparium ovoid to slightly wider than long; cuticle usually dark brown to black with little wax secretion; margin crenulate, modified at thoracic tracheal openings; dorsal papillae present, usually with a submarginal row and others present on dorsal disc, the papillae variably developed, but generally somewhat flat, plate-like; transverse moulting suture reaching submargin; median length of abdominal segments VI and VII similar; each cephalic seta situated on the lateral apex of a superficial thumb-shaped ridge; submargin of cephalothorax with seven pairs of setae; submargin of abdomen with eight pairs of setae; vasiform orifice cordate, entirely occupied by the operculum, with its floor divided in half in most species, with posterior half often reticulate, and head of lingula lobed, but covered by operculum; with a short apical groove, defined by a pair of variably developed caudal ridges ending in a pair of caudal setae; ventrally, the tracheal folds well defined and the legs aligned mesally by a band of blunt spines ( Martin 2005).
