Aflagellate and immotile spermatozoa of three species of whitefly, Bemisia tabaci, Dialeroudes citri and Trialeroudes vaporariorum (Aleyrodidae), are described. In these three species, axoneme and mitochondria are present in the early spermatid, but degenerate in the later stages. The acrosome has arborescent appendages that almost completely surround the spermatozoan. In D. citri the acrosomal projections are more elongated and branched than in T. vaporariorum and B. tabaci . Nuclear and cell elongation appear to occur in the absence of microtubules.
