Remarks
- Structure: Scale of adult female approximately 1.75 mm diameter, circular, white, with a yellowish brown, subcentral exuviae. Male scale not observed (McKenzie, 1953a). Colour photograph by Gill (1997).
- Economic Importance: Gill (1997) recorted that heavy populations on Euphorbias in California may require control.
- General Remarks: Description and illustration of adult female by McKenzie (1953a, 1956), Mamet (1958a) and by Gill (1997). Schutze et al. (2026) consider this species to have been present in Australia as non-native in the past, but is likely extirpated.
