<p> Mealybugs (Hemiptera: Sternorrhycha: Pseudococcidae) are important agricultural pest that affect hundreds of plants species of economic importance. This taxonomic study of Puerto Rico's pseudococcids contains a list of the actual pseudococcids including their descriptions, biology and hostages range of each species. This study also develops a taxonomickey and reference collection of pseudococcids of Puerto Rico including the species of most economic importance and those of recent introduction. For the Puerto Rico's pseudococcids were reviewed the works of Wolcott (1948), Martorell (1976), Nakahara and Miller (1981), Williams and Granara de Willink (1992), Gimpel and Miller (1996), Granara de Willink (2009), USDA/APHIS/PPQ (1989 - 2013). It was obtained a list of 47 species in 20 genus of Pseudococcidae of Puerto Rico. The taxonomy and classification of the mealybugs it is based in the morphology of females. There have been phylogenetic studies in which it is pretended to establish their principal clades as those of Downie and Gullan (2004) and Hardy et al (2008) which recovered two primary clades of Pseudococcidae, to which they applied the names of subfamilies, Phenacoccinae and Pseudococcinae. Applying Hardy et al (2008) classification to the species of Puerto Rico there was left 19 genus and 46 species as Hardy excluded the genus Puto from Pseudococcidae and put it in Putoidae. From 2008 to 2010, 72 field samples were collected, which are parts of vegetable crops and unknown ornamental plants were found affected by Pseudococcidae. The sampling is centered in 20 towns of Puerto Rico. There were identified 15 species that do harm to crops. This works has shown the need to generate more information about Pseudococcidae in Puerto Rico. To the effect of this study of mealybugs it were reported 14 species of pseudococcids. To present time there have reported 47 species of which one of them is another family Putoidae.</p>
