A new genus of Neotropical whitefly,secreting blue-iridescent wax (Sternorrhyncha,Aleyrodidae, Aleurodicinae), and its parasitoids (Hymenoptera,Aphelinidae)

Azuraleurodicus pentarthrus Martin gen. and sp. n. is described from three different host plant families in Central and northern South America. Adults of both sexes were reared in culture and adult characters are discussed in addition to those of puparia. The systematic position of Azuraleurodicus within the Aleurodicinae is discussed. One new combination, Aleuronudus ferrisi (Sampson and Drews) comb. n., is here proposed in the course of discussion. The secretion of blue wax by whiteflies is discussed and illustrated by colour photographs. Two species of hymenopterous parasitoids, Dirphys aphania Polaszek sp. n. and Encarsiella pithecura, Polaszek sp. n. emerged from puparia of Azuraleurodicus pentarthrus and are here described.
