Systematics: This species was originally described in Coccus Linnaeus. Walker (1852) transferred it to Aspidiotus Bouche, in the Diaspididae. Targioni Tozzetti (1868) and Signoret (1869) assigned it to Lecanium. Fernald (1903b) placed it among the unrecognizable species of Coccus. Lindinger (1912b) suggested that it was a synonym of Chionaspis salicis in the Diaspididae. Borchsenius (1966) interpreted it an armoured scale, Aspidiotus hordeolum while listing it among the species incertae sedis. In ScaleNet we regard Coccus hordeolum Dalman, 1826 as a species in the family Coccidae, for two reasons. 1. The original description (Dalman, 1826) included brief textual description that reads "The female oval or almost elliptical, yellow, smooth, shining, with a little raised back ... looks like a boat upside down", as well five Figures (Figs 1-5, Tab. IV). In Figs. 3&4, Dalman clearly illustrated an anal cleft. 2. J.W. Dalman (1787-1828), who was also a taxonomist of hymenopterous parasites, described in this 1826 paper, Entedon scutellaris and E. insidiator, which he found to parasitize Coccus hordeolum. These parasitoids are currently known as Coccophagus scutellaris and C. insidiator in the Aphelinidae. The recorded host range of both species is almost exclusively species of the Coccidae.
