• Erium Cockerell, T.D.A. 1897. Contributions to Coccidology. – II. American Naturalist 31: 588-592 [590] [introduced as a subgenus of Dactylopius. Fernald, M.E. 1903. A catalogue of the Coccidae of the world. Bulletin of the Hatch Experiment Station of the Massachusetts Agricultural College 88: 1–360 and Lindinger, L. 1935. Neue Beiträge zur Kenntnis der Schildläuse (Coccidae). Entomologische Zeitschrift 49: 121–123 credited the genus to Crawford. However, Morrison, H. & Morrison, E.R. 1966. An annotated list of generic names of the scale insects (Homoptera: Coccoidea). Miscellaneous Publication United States Department of Agriculture 1015: 1–206 discussed the nomenclature and concluded that the author was Cockerell].
