Putoidae is a family of scale insects commonly known as giant mealybugs or putoids. There is probably a single genus, Puto, containing about sixty species. The genus name Macrocerococcus has also been used but it is now considered to be a synonym of Puto. The genus Puto was formerly classified as a member of the Pseudococcidae; however, it so significantly differed from the rest of the Pseudococcidae that it was accorded its own family Putoidae.
