Remarks

• Systematics: Diaspis radicicola is very similar to D. echinocacti and were it not for the differences in habit and scale characteristics it could be considered an extreme variant (Ferris, 1937). McDaniel (1971) states that D. radicicola can be separated from the other species by the median lobes that are apically acute and the second and third lobes which are both quite well developed.
• Structure: Female scale brown, rather hard and brittle, very flat, scarcely distinguishable from the substratum, circular; exuviae subcentral. Male scale yellowish, elongate, felted; exuviae at one extremity (Ferris, 1937).
• General Remarks: Best description and illustration by Ferris (1937).
