Live Appearance and Habitat
Female scale cover opaque, circular, flat, exuvia central; male scale cover elongate, carinate with pale terminal exuvium, and associated white woolly wax. Female body creamy with dark pygidium when young, pale yellow when mature, eggs yellow. On leaves of host plants.
Diagnosis
Adult female body turbinate, prosoma with an ear-like lobe each side (occasionally lacking in some specimens); apex of pygidium with deep notch formed by recessed median lobes; each lobe diverging, serrate, the inner margins longer than outer margins. L2 and L3 rounded, bilobate, the lobules of each about same size, unilobate L4 present. With a pair of setae in medial space. Gland spines present singly lateral to L1 between lobes and more numerous on prepygidial abdominal margins to segment II. Marginal macroducts 2-barred, 6 pairs plus 1 macroduct between median lobes, and 2 pairs of macroducts submarginally by L2 and L3. With a lateral spur on margin at position of each 6th macroduct.
Dorsal ducts becoming smaller anteriorly. Anal opening small, positioned in posterior 1/3 of pygidium. Antenna with 1 seta. Anterior spiracles each with a small group of trilocular pores, absent from posterior spiracles. Perivulvar pores present in 5 compact lozenge-shaped groups.
