Examination of type specimens and other authentic material established that the earliest available name for the long brown scale is Coccus longulus (Douglas), stat. n. and that Lecanium elongation Signoret is a junior synonym of Parthenolecanium persicae (F.), syn. n. Detailed, illustrated descriptions of adult female C. longulus are given, based on collections from England, Australia, Israel and the U.S.A. Lectotypes are designated for C. longulus, Lecanium frontale Green and Lecanium acaciae Newstead. Coccus acaciae (Newstead), stat. n. is raised from synonymy and seven synonyms of C. longulus are listed.
