Key to the world genera of Aleurodicinae – puparia
This key includes all genera of Aleurodicinae , as understood by the present author. Genera that are natives of the New World are indicated in bold italics, the others in italics only.
Quoted counts of submarginal setae include the nominal caudal pair, but not the anterior and posterior marginal setae.
Note that the pair of posterior abdominal spiracles (ventral, abdominal segment VIII) can be mistaken for small post-vasiform orifice compound pores (dorsal). Figure 3 View FIGURES 1–4 is a good example, being without any small compound pores, but with the spiracles clearly visible in a similar position.
