Remarks

• Biology: Occurring on the foliage of its host plant.
• General Remarks: Good description and illustration of the adult female given by Ferris (1950b) and by McKenzie (1967). Ferris (1950b) comments that most of the published records under the name of ryani are misindefications of Spilococcus implicatus or Spilococcus andersoni. Ferris (1918d) erroneusly synonimized Dactylopius andersoni Coleman and D. dudleyi Coleman with D.ryani.
