GRANARA DE WILLINK, María Cristina  y  SZUMIK, Claudia. Central and South American Phenacoccinae (Hemiptera: Coccoidea: Pseudococcidae): Systematics and Phylogeny. Rev. Soc. Entomol. Argent. [online]. 2007, vol.66, n.1-2, pp.29-129. ISSN 0373-5680.

A systematic and cladistic study of the Neotropical Phenacoccus Cockerell is presented. A total of 18 new species of Phenacoccus are described and illustrated: Phenacoccus argentinus Granara de Willink, Ph. berberis Granara de Willink, Ph. chubutensis Granara de Willink, Ph. ornatus Granara de Willink, Ph. persimilis Granara de Willink (Argentina); Ph. erythrinus Granara de Willink (Brazil and Argentina); Ph. peruvianus Granara de Willink (Argentina and Peru); Ph. sisymbriifolium Granara de Willink (Argentina and Uruguay); Ph. chilindrinae Granara de Willink, Ph. cornicirculus Granara de Willink, Ph. ruellia Granara de Willink, Ph. setosus Granara de Willink, Ph. sonoraensis Granara de Willink (Mexico); Ph. hirsutus Granara de Willink (Puerto Rico); Ph. multicerarii Granara de Willink (Venezuela); Ph. sisalanus Granara de Willink (Haiti and Dominican Republic); Ph. toconaoensis Granara de Willink (Chile), and Ph. uruguayensis Granara de Willink (Uruguay). All the previously known species of Phenacoccus (24) for the region are diagnosed. Phenacoccus artemisiae Ehrhorn and Ph. graminicola Leonardi, recorded for the first time in Argentina, are redescribed and illustrated. Keys to the Neotropical Phenacoccinae genera and to the Neotropical species of Phenacoccus are included, as well as a list of Phenacoccus host plants which contains 48 plant families and 124 species. Finally a cladistic analysis on the Neotropical Phenacoccinae which includes the following genera: Phenacoccus Cockerell, Brasiliputo Williams & Granara de Willink, Brevennia Goux, Chileputo Williams & Granara de Willink, Heliococcus Sulc, Heterococcus Ferris, Mammicoccus Balachowsky, Peliococcus Borchsenius, Pellizzaricoccus Kozár, is discussed here. A data matrix of 60 taxa (10 genera) and 111 morphological characters is analyzed under the parsimony criteria, using the genus Puto Signoret as the outgroup. The results indicate that Phenacoccus is paraphyletic in terms of Brasiliputo, Brevennia, Pellizzaricoccus, Peliococcus, Heterococcus, Mammicoccus and Heliococcus. Only Mammicoccus and Peliococcus are monophyletic.
