Diagnostic Notes
Adult Female

Membranous, elongate, more than twice as long as wide. Pygidium with median lobes not zygotic, with a pair of setae present between their bases; dorsum of pygidium with 60-75 scattered dorsal macroducts present.

Field Characters

Scale cover of adult female mussel-shaped, up to 2.5 mm long; slightly convex, brown or brown-black with a paler margin, moderately convex and often with a distinct longitudinal dorsal ridge; with brown-yellow terminal exuviae. Scale cover of male smaller than that of female, white, elongate oval, with three longitudinal ridges and yellow-brown terminal exuviae. The male scale covers often form conspicuous groups on bark - hence the common name, citrus snow scale.
