Live Appearance and Habitat

Female scale cover almost circular when newly moulted female under the 2nd-exuvium, cover extending to a tapered, elongate shape when mature, the waxy part serving to harbour a double row of eggs; terminal exuvia usually in shades of green with caramel lateral margins, 1st-exuvium either dark olive green or charcoal; female body pale with red markings at first, becoming purple, eggs purple, crawlers dark red-brown. Male scale cover smaller and narrower than female cover, the terminal exuvium dark green/grey, the elongate waxy part lighter shades. On leaves of host plants.

Diagnosis

Adult female: body oval to circular with a wide, rounded pygidium, with median lobes (L1) each with 1 notch on each side and apically pointed, L2 and L3 similar in shape and smaller; body length 0.58–0.92 mm, width 0.51–0.67 mm. Submarginal ducts on prepygidium numerous, 25–46 ducts each side. Submedian ducts absent. With numerous dorsal microducts on prepygidium abdomen and metathorax. Anal opening diameter 12–15 µm, positioned 75–95 µm from posterior margin.

Ventral microducts few on abdomen, scattered by spiracles, more numerous on submargin of thorax. Derm pocket present, of variable shape (through being squashed) on slide-mounted specimens. Antennal tubercle tall, with 1 seta set near basal 1/3. Anterior spiracles each with a group of 2–4 5-locular pores. Total of 48–83 perivulvar pores in 2 elongate lateral groups.
