Miller, D.R., Gullan, P.J., & Williams, D.J. 1998 Family placement of species previously included in the scale insect genus Sphaerococcus Maskell (Hemiptera: Coccoidea).. Proceedings of the Entomological Society of Washington 100: 286-305.

Notes: The genus "Sphaerococcus" Maskell includes many rotund scale insects that do not seem to fit elsewhere; family placement of many species into Pseudococcidae is questionable or unknown; purpose of paper is to provide correct family placement of each species described in this genus; 12 taxa are transferred to new families; five new combinations and one new synonymy.
