Abstract

The identity of Phenacoccus gossypii Townsend & Cockerell is established as a local species in Mexico and southern USA. Although P. madeirensis Green was described from Madeira and is recorded from much of the African mainland, it was probably introduced from tropical America. It is now known to be common on many crop and ornamental plants in North and South America where it has often been mistaken for P. gossypii. Both species are redescribed and illustrated, and their range of variation is discussed. P. grenadensis Green & Laing and P. harbisoni Peterson are synonymized with P. madeirensis. A related species, P. baccharidis sp. n., is described from Brazil, and P. sphaeralceae sp. n. is described from Arizona. P. hurdi McKenzie is redescribed and is now recorded from an extensive area in southern USA and Mexico. All five species have numerous dorsal multilocular pores and are included in a key to 15 related species in North and South America.
