Remarks

• Systematics: The 1st-instar nymph of A. cordylinidis differs from that of A. gahniae in having 1 pair of gland spines 2× as long as the median lobes on the pygidium, and 1 pair each of large and small microducts on the dorsal thorax; on A. gahniae dorsal submedian ducts are absent and pygidial gland spines either not produced beyond margin or only <1.5× as long as the the median lobes. As for A. angusta and A. gahniae, features of the 1st-instar nymph that differentiate it are also present in the 1st-exuvium of the scale covers, these proving a valuable aid to distinguish this species. (Henderson, 2011) The male nymph of A. cordylinidis possesses 1 pair of dorsal ducts on pygidium VI, whereas A. gahniae has 2 pairs there, a submedian and a submarginal duct each side; in addition, usually the antenna on A. cordylinidis has 1 long seta whereas the antenna on A. gahniae has 2 divergent long setae. (Henderson, 2011)
• Structure: Female scale very long and narrow, generally straight, sometimes curved, semi-cylindrical, white, but exuviae are bright yellow. Eggs are small, oval, bright yellow. Adult female pale golden, three times as long as broad. Body is somewhat corrugated (Maskell, 1879). Female scale elongate, more so when on Cordyline than on Freycinetia, Phormium, or Uncinia; scale cover white, terminal exuvia pale when on Cordyline, dark brown when on Freycinetia, Phormium, or Uncinia. Female body and eggs yellow. Male scale small, elongate, not carinated, white with pale terminal exuvium. (Henderson, 2011)
• Biology: On leaves of host plant.
