Systematics: Ceroplastes planus belongs to the C. floridensis species-group because it has ventral tubular ducts, each with a very short, swollen inner ductule, forming a submarginal band; however, it can be easily distinguished from other species in this group by its distinctive, flat-topped cake-like wax test; multilocular pores confined to middle area of abdominal segments VI–VII; the filamentous dorsal ducts forming a submarginal band, and by having fewer stigmatic setae (only 5–14 per cleft), which usually are arranged in a single row. (Wu & Wang, 2019)
Structure: Wax test of adult female round, cake-like, diameter 1.8–2.8mm, height 1.2–1.8mm. Wet wax circular in dorsal view, nearly flat in lateral view, without either dorsal horn, plates or nuclei, but with a large marginal flange. Dry wax with filaments as follows: cephalic filament appearing trifurcate; interolateral and mediolateral filaments simple; posterolateral filaments bifurcate; caudal filaments simple. Dorsal dry wax of first- and second-instar nymphs forming a small cap, not surrounded by nucleus; dorsal dry wax tilted anteriorly. Dry wax filaments usually darkened by contamination with dust. Stigmatic wax bands present near both pairs of spiracles, anterior bands directed dorsally; filamentous wax confined to stigmatic areas. (Wu & Wang, 2019)
