Remarks

• Systematics: "Asterolecanium ilicis, described by Newstead in 1897 (p.100) as Planchonia ilicis on "scurb" from Constantine, Algeria, was listed as a synonym of variolosum by Lindinger in 1912 (280, 360), but has been accepted as a valid species by some authors, including Balachowsky (1932d, p. xxiv). Newstead stated that ilicis was closely related to ilicicola, but that the two could be differentiated by the absence of a marginal fringe from the tests of the former and the presence of such a fringe on those of the latter. This is not satisfactory for separating the two forms. Newstead did not compare the morphological characters of these species, and type material of ilicis has been available to the writer. Specimens on Quercus from Constantine, Algeria, have been studied, however, and have been found specifically identical with specimens of ilicicola from Europe. Since there is no information in the original description to warrant the retention of ilicis as a valid species, and since specimens from its type host and locality belong to ilicicola, ilicis is here [Russell, 1941] synonymized with ilicicola." (Russell, 1941: 107-108).
• Biology: Colonies of these scales settle on the upper surface of leaves of Q. ilex.
