Adult Female

1.0-1.4 mm long, somewhat inflated and marginally sclerotized with maturity but never becoming reniform. Prepygidial abdominal segments 1-3 each with a row or cluster of dorsal submarginal macroducts on either side. Pygidium with paraphyses present, most or all no longer than median lobes; perivulvar pores present in 4 (occasionally 5) groups; prevulvar apophyses and scleroses absent; plates lateral to third lobes each with a single fleshy process.

Field Characters

In life, scale cover of adult female 1.5-2.6 mm diameter, circular to oval, flat, off-white to pale brown or yellow, with yellow to dark brown exuviae positioned more or less centrally. Beneath the scale cover, the adult female insect is pyriform initially, expanding with maturity to subcircular and becoming moderately sclerotized around margins. Scale cover of male similar in colour to the female but smaller, elongate oval, with subterminal yellow exuviae. Adult male winged.
